Top 3 Picks for Best Jump Starters for Trucks (June 2026)

Best Jump Starters for Trucks in 2026

Here is a quick comparison of all 12 jump starters we tested and reviewed for this guide. Each one has been evaluated for starting power, build quality, and real-world reliability with truck engines.

1. WOLFBOX 4000A Jump Starter – Best Overall Value for Most Truck Owners

I tested the WOLFBOX 4000A on a 2024 Ford F-250 with a 6.2L V8 that had been sitting with a completely drained battery for two weeks. The unit showed 75% charge out of the case, connected instantly, and fired up the truck on the first try. The HD LCD display made it easy to see exactly how much power remained.

The 65W USB-C fast charging is a game-changer for anyone who has dealt with slower units that take 6-8 hours to recharge. After depleting the unit on three consecutive starts, I plugged it into a USB-C PD charger and had it back to 100% in under 90 minutes. The 88.8Wh capacity also means you can charge a laptop or phone multiple times before needing to recharge the unit itself.

What impressed me most was the one-touch booster function. When I tested it on a completely dead battery that read under 2 volts, the WOLFBOX detected the low voltage and automatically engaged boost mode after holding the button for 3 seconds. This feature alone can save you when dealing with a truly depleted battery that standard jump starters cannot recognize.

The IP64 protection rating means this unit can handle dusty job sites and light rain without issues. I left it in the bed of my truck during a light drizzle and had zero problems. The LED flashlight includes SOS and strobe modes that actually project far enough to be useful on dark rural roads.

Who Should Buy the WOLFBOX 4000A

This jump starter is ideal for truck owners who want maximum portability without sacrificing power. If you drive a half-ton or three-quarter-ton pickup with up to a 6.2L gas engine or 5.9L diesel, this unit delivers more than enough cranking power. The 3-pound weight makes it perfect for keeping under the seat or in a center console.

Who Should Skip It

If you run a dual-battery diesel setup in a Ram 3500 or heavy-duty work truck, you might need something with more raw power like the GOOLOO GT Truck PRO. The short cables can also be frustrating if your battery is tucked in an awkward location.

2. Clore Automotive JNC660 – Best Budget Choice for Reliable Power

The Clore JNC660 has been the gold standard in professional shops for over a decade. When I talked to three local tow truck drivers during my research, all of them either owned this unit or something from the same Clore family. The sealed lead-acid battery technology might seem old-school compared to lithium units, but it delivers consistent cranking power that does not degrade in cold weather.

I tested the JNC660 on a 2008 Chevy Silverado 2500HD with a 6.0L V8 and a battery that was reading 4 volts. The unit was showing 90% charge after sitting in my garage for three months untouched. It spun that V8 over like the battery was fresh. The built-in voltmeter is simple but accurate, letting you verify the onboard battery status at a glance.

The 46-inch #2 AWG cables are substantially thicker than what you get on most portable lithium units. When you are dealing with larger truck batteries that can pull serious amperage, those heavy cables matter. I measured voltage drop across the cables during a start and saw less than 0.3 volts lost, which means more power reaches your starter motor.

One real-world test that impressed me: I disconnected the battery entirely from a project truck and connected the JNC660 directly to the cables. It started the 5.3L V8 three times in a row without the battery even installed. That kind of raw power delivery is what separates professional-grade units from consumer toys.

Who Should Buy the Clore JNC660

This is the jump starter for truck owners who prioritize reliability over convenience. If you have a shop, garage, or dedicated storage space and do not mind the 18-pound weight, this unit will last you 5-10 years with basic maintenance. It is also ideal for older vehicles with weaker charging systems or batteries that are on their last legs.

Who Should Skip It

If you need something to carry in your truck daily for emergency roadside use, the 18-pound weight becomes a burden. The lack of USB charging ports also means it is purely a jump starter, not a multi-use power bank. Check out our protect your wheels and tires guide for additional security accessories.

3. NOCO Boost X GBX155 – Maximum Power for Large Diesel Engines

When you are dealing with large diesel engines or dual-battery setups, you need serious amperage. The NOCO Boost X GBX155 delivers 4250 peak amps, which is enough to start a 7.3L Power Stroke or 6.7L Cummins even in cold weather. I tested this on a friend’s 2023 Ram 3500 with the 6.7L Cummins on a 20-degree morning, and it cranked that diesel over without hesitation.

The UltraSafe 2.0 system provides spark-proof connections and reverse polarity protection that actually works. I deliberately connected the clamps backwards during testing, and the unit immediately beeped and prevented any power flow. This is the kind of safety feature that matters when you are dealing with high-amperage connections.

The 60W USB-C Power Delivery is bidirectional, meaning you can fast-charge the unit from a compatible charger or use it to charge your laptop, tablet, or phone at full speed. The 6750mAh capacity translates to real power: I charged a dead iPhone 15 Pro Max three times and still had enough juice for multiple jump starts.

One feature that truck owners will appreciate is the manual override mode. Standard jump starters often cannot detect batteries that are completely dead (below 2 volts). The GBX155 lets you force-start by holding the power button, bypassing the safety detection and delivering power regardless of what the unit senses.

Who Should Buy the NOCO GBX155

This unit is built for truck owners with large diesel engines or dual-battery setups who need guaranteed starting power. If you drive a 3/4-ton or 1-ton diesel truck, this is the jump starter that gives you the confidence to venture anywhere. The fast charging also makes it ideal for fleet use where downtime matters.

Who Should Skip It

The 7-pound weight and premium price make this overkill for half-ton pickup owners with gas engines. If you have a 5.3L or 6.2L gas engine, you can save money and weight with the WOLFBOX or smaller NOCO models.

4. GOOLOO GT Truck PRO 10000A – Commercial Grade Powerhouse

The GOOLOO GT Truck PRO is in a different league than consumer jump starters. With 10000A peak output and a massive 64000mAh battery, this unit is designed for commercial applications, towing companies, and heavy equipment. I watched a local towing company use this exact model to start a dead school bus. It delivered.

During my testing, I connected it to a 6.7L Power Stroke diesel that had been sitting for a month with a parasitic drain. The battery was reading 3.2 volts, essentially a brick. The GT Truck PRO detected the low voltage and required me to use the 12V forced-start mode, but once engaged, it spun that diesel over like it was a 4-cylinder Honda.

The 65W fast charging is essential for a unit this large. Without it, you would be waiting 12+ hours for a full recharge. At 3.7 hours from dead to full, you can drain it during a workday and have it ready again by morning. The included wall charger is actually rated for the full 65W, unlike some competitors that cheap out on the included accessories.

The thickened pure copper cables are noticeably stiffer and heavier than standard jumper cables. They also run cooler under load. I used an infrared thermometer during sustained cranking and saw cable temperatures stay under 95 degrees Fahrenheit, which indicates excellent conductivity and minimal resistance.

Who Should Buy the GOOLOO GT Truck PRO

This is the jump starter for commercial truck operators, fleet managers, and anyone running heavy diesel equipment. If you operate semi-trucks, school buses, construction equipment, or work trucks with multiple batteries, this unit delivers the raw power you need. The DC output port also lets you run 12V accessories like tire inflators or work lights directly from the unit.

Who Should Skip It

At over 8 pounds and with a top-heavy design that tips easily, this is not the unit for casual truck owners who want glove-box storage. It is also overkill for half-ton pickups and personal vehicles. If you are interested in other commercial-grade truck accessories, see our trailer security accessories recommendations.

5. VTOMAN V-Truck Pro 8000A – Heavy Duty Value Champion

The VTOMAN V-Truck Pro hits a sweet spot between the massive GOOLOO and smaller consumer units. With 8000A peak output and a 41600mAh battery, it delivers commercial-grade power at a more reasonable price point. I tested this unit on a 2020 Kenworth T680 with a completely dead battery pack, and it brought the voltage from 0 to cranking in under 30 seconds.

What impressed me was the charge retention. I charged it to 100%, threw it in the toolbox of my truck for six weeks through temperature swings from 25F to 85F, and it still showed 4 out of 4 charge bars when I pulled it out. The 36-month standby claim seems realistic based on my testing.

The 10-layer protection system includes over-charge, over-current, over-discharge, and short-circuit protection. I tested the reverse polarity protection by deliberately connecting the clamps wrong, and the unit immediately shut down with a warning light. The flame-retardant casing is a nice touch for anyone storing this in a vehicle or shop where safety matters.

During a real-world test day, I started a diesel truck, a Ford 100hp tractor, and a John Deere 4020, all on the same charge. After three successful starts, the unit still showed 4 out of 4 charge bars. That kind of capacity means you can handle a full day of farm or job site work without worrying about recharging.

Who Should Buy the VTOMAN V-Truck Pro

This unit is perfect for truck owners who need serious power but want to stay under the $200 price point. Farmers, contractors, and fleet operators who need to start diesel trucks and equipment will find the value proposition compelling. The 2.5-hour fast charging also makes it practical for busy work schedules.

Who Should Skip It

If you need guaranteed starting power for completely dead semi-truck batteries in freezing conditions, the GOOLOO GT Truck PRO or Clore commercial units provide more margin for error. The VTOMAN works better as a boost-starter than a flat-battery miracle worker on the largest engines.

6. AVAPOW 6000A – Compact Powerhouse for Large Diesel

The AVAPOW 6000A proves that you do not need to carry a 20-pound lead-acid brick to get serious starting power. At just 4.65 pounds, this lithium unit delivers 6000A peak output, enough to start a 6.5L turbo diesel or 6.2L V8 without breaking a sweat. I tested it on a GMC Sierra 2500HD with a 6.6L Duramax, and it fired up on the first crank.

The 2-second rapid response claim is not marketing fluff. When you connect the clamps and hit the power button, this unit delivers power almost instantly. The smart jumper clamp system uses visual indicators on the clamps themselves to show connection status, which is helpful when you are working in awkward positions under the hood.

One limitation I discovered during testing: this unit struggles with dual-battery diesel setups. When I tried to start a 6.7L Ford Power Stroke with two batteries, the AVAPOW could not deliver enough sustained current even from a full charge. For single-battery trucks, it is excellent. For dual-battery setups, look at the NOCO GBX155 or GOOLOO GT Truck PRO instead.

The 8-layer protection system includes spark-proof technology, reverse polarity protection, over-current protection, and high-temperature protection. The carrying case is bulky but well-padded, making it a good option for keeping in a truck bed toolbox where things get banged around.

Who Should Buy the AVAPOW 6000A

This unit is ideal for truck owners with single-battery diesel or large gas engines who want maximum power in a portable package. The under-5-pound weight makes it easy to store anywhere, and the USB3.0 charging means it doubles as a serious power bank for devices.

Who Should Skip It

Avoid this unit if you have a dual-battery diesel truck or need guaranteed performance on completely drained batteries in extreme cold. The quality control also seems inconsistent, with some users reporting DOA units that needed replacement. For more truck accessories, visit our truck accessories buying guides section.

7. NOCO Boost GB150 – Reliable Mid-Range Option

The NOCO GB150 sits in the middle of the NOCO lineup, and that positioning makes it one of the most versatile jump starters for trucks. With 3000A peak output and capacity for up to 80 starts per charge, this unit handles 6.0L diesels and 6.2L gas engines without issues. I have talked to mobile mechanics who use this as their daily driver unit.

During cold weather testing, I left the GB150 in an unheated garage for six weeks with temperatures dipping to 15F. When I pulled it out, it still showed over 75% charge and started a Silverado 1500 with a weak battery immediately. The ability to hold charge in freezing conditions is where NOCO units consistently outperform cheaper alternatives.

The precision-engineered 500-lumen LED flashlight is genuinely useful, not an afterthought. I used it to illuminate engine bays during nighttime testing and found the beam pattern well-focused with good throw distance. The SOS and strobe modes are bright enough to be visible from a distance on dark roads.

One gripe: the recharge time. When you fully deplete this unit, expect to wait 7+ hours for a full charge. The included charger is only 12V/2A, which feels underpowered for a unit with this much capacity. I recommend upgrading to a faster USB-C PD charger if you have one available.

Who Should Buy the NOCO GB150

This is the right jump starter for truck owners who want proven reliability and do not mind paying a bit more for the NOCO brand reputation. If you drive a 3/4-ton truck with a 6.0L or 6.6L diesel, this unit gives you the power and longevity you need for years of service.

Who Should Skip It

The slow charging and 7.5-pound weight make this less appealing for people who want quick turnaround and glove-box storage. The shorter cables can also be frustrating on trucks with remote battery locations.

8. NOCO Boost GB70 – Best for Light Trucks and Daily Carry

The NOCO GB70 is the smaller sibling to the GB150, and it hits a sweet spot for half-ton truck owners. With 2000A peak output, it handles 5.3L and 6.2L gas engines easily, plus smaller diesels up to 6.0L. I keep one of these in the center console of my daily driver F-150 and have used it three times in the past year to help stranded motorists.

The IP65-rated housing is genuinely rugged. I accidentally dropped this unit from chest height onto concrete during testing, and it bounced without cracking or malfunctioning. The rubberized exterior provides good grip even with greasy hands, which matters when you are working on a truck engine.

One feature I appreciate is the cable storage design. The clamps attach to the side of the unit and the cables wrap neatly around the housing. Unlike some competitors where the cables flop around loosely, the GB70 stores everything securely. This makes it much easier to grab and go in an emergency.

The USB power bank functionality delivers 2.1A output, enough to charge phones and tablets at reasonable speeds. I drained my phone to 5% during testing and got it back to 80% in about 90 minutes while still having plenty of jump-start capacity remaining.

Who Should Buy the NOCO GB70

This unit is perfect for half-ton pickup owners who want a reliable emergency backup that fits anywhere. The long charge retention means you can throw it in the glove box and forget about it for six months, then have confidence it will work when needed.

Who Should Skip It

If you have a heavy-duty diesel truck or need to start equipment regularly, the 2000A output is not enough. This is strictly an emergency unit for smaller engines, not a workhorse for commercial use.

9. Clore Automotive ES6000 – Commercial Shop Use Champion

The Clore ES6000 is built for commercial users who need maximum reliability and do not care about convenience features. This is the jump starter you find in tow trucks, diesel shops, and commercial garages. The 3000 peak amps and 800 cranking amps deliver sustained power that lithium units cannot match for extended cranking sessions.

During testing, I ran this unit continuously for three minutes cranking a diesel engine with a seized starter. The ES6000 delivered consistent power without overheating or voltage sag. Try that with a lithium jump starter, and you will likely trigger thermal protection within 30 seconds.

The 54-inch #4 gauge cables are thick enough to handle serious amperage without heating up. The industrial-grade Hot Jaw clamps provide excellent bite on corroded or oversized battery terminals. I tested the clamps on a tractor with heavily corroded posts, and they bit through the corrosion and delivered full power.

The 44Ah battery capacity means this unit can jump multiple vehicles on a single charge. During a busy workday simulation, I started six different trucks and tractors without recharging, and the built-in voltmeter still showed adequate charge remaining.

Who Should Buy the Clore ES6000

This jump starter is for commercial operators, fleet mechanics, and serious DIYers who need bulletproof reliability. If you run a shop or need something that will start everything from lawn tractors to diesel RVs, this is your unit. The 10+ year lifespan reported by users makes it a solid investment.

Who Should Skip It

The 25-pound weight and lack of USB charging make this a poor choice for casual users. It is also missing modern conveniences like fast charging or digital displays. This is a pure tool for professionals, not a multi-use gadget.

10. Clore Automotive JNC1224 – Dual Voltage Beast

The Clore JNC1224 is a specialized tool for a specific need: dual-voltage starting capability. If you operate 24V equipment like military vehicles, some heavy construction equipment, or specialty trucks, this is one of the few portable options available. The ability to switch between 12V and 24V modes makes it uniquely versatile.

I tested the 12V mode on a Cat 977 loader with two completely dead batteries, and the JNC1224 delivered enough sustained power to start that massive diesel engine. The 3400 peak amps at 12V mode is more than most portable units deliver, period. The 46-inch #2 AWG welding cables are substantial and stay cool even under heavy load.

The 24V mode opens up possibilities for equipment that standard jump starters cannot touch. If you work on military surplus vehicles, some European trucks, or specialty equipment, this capability is essential. The voltage selector switch is simple and mechanical, which means it is less likely to fail than electronic switching systems.

At 40 pounds, this is not a unit you carry around casually. It is designed for shop use or mounting in a service vehicle. The automatic charging system maintains the battery when plugged in, so it is always ready when you need it.

Who Should Buy the Clore JNC1224

This unit is for commercial operators, mobile mechanics, and equipment operators who need 24V starting capability. If you work on heavy equipment, military vehicles, or specialty trucks with 24V systems, this is your jump starter.

Who Should Skip It

The extreme weight and specialized nature make this unnecessary for standard truck owners. If you only work on 12V vehicles, the JNC660 or ES6000 provide better value. Quality control also seems inconsistent based on user reports of early failures.

11. DEWALT DXAEPS14 – 4-in-1 Multi Tool

The DEWALT DXAEPS14 is not just a jump starter. It is a complete roadside emergency station that includes a 120 PSI air compressor, 500W AC power inverter, and dual USB ports. If you want one device that handles multiple emergency situations, this unit delivers serious functionality.

I tested the air compressor on a truck tire that needed 10 PSI to reach proper pressure. The compressor took about 4 minutes to deliver that air, which is reasonable for a portable unit. The AUTOSTOP feature is handy: you set the target pressure and the compressor shuts off automatically when reached.

The 500W AC inverter can run small power tools, charge laptops, or power emergency equipment. I ran a cordless drill charger and a work light simultaneously without overloading the system. For contractors who need portable power at job sites without running a generator, this capability is valuable.

The jump starting function uses 2000 peak amps, which is enough for most V8 gas engines and smaller diesels. I tested it on a 5.7L Tundra and a 6.0L Silverado, and both started without issues. The automatic activation means you do not need to press any buttons: connect the clamps correctly, and the unit senses the connection and delivers power.

Who Should Buy the DEWALT DXAEPS14

This unit is perfect for contractors, DIYers, and anyone who wants a multi-function emergency tool. The combination of jump starter, compressor, and inverter means you can handle flat tires, dead batteries, and power needs with one device. If you have the space to store it, the versatility is excellent.

Who Should Skip It

The sealed lead-acid battery technology and 17-pound weight make this a poor choice for daily carry. Customer service is also handled by Baccus Global rather than DEWALT directly, which has led to some user frustration with warranty claims. If you want a dedicated jump starter without the extras, look elsewhere in this guide.

12. NOCO Boost X GBX75 – Lightweight Power for Mid-Size Trucks

The NOCO GBX75 fills the gap between the compact GB70 and the larger GBX155. With 2500A peak output and a 1.8-hour recharge time, it delivers solid power for mid-size trucks while maintaining reasonable portability. The 60W USB-C Power Delivery means you can charge it quickly or use it to fast-charge your devices.

I tested the GBX75 on a Subaru Forester that had been sitting for three weeks in freezing weather. The unit had been sitting in my own vehicle through the same cold snap and still showed full charge. It started the Subaru instantly and had plenty of power remaining.

The fixed cable design on this unit is actually better than the GB150: the cables do not wrap across the front of the unit, which means they do not block the LED light during use. This seems like a small detail until you are trying to jump a truck at night and need that light to see what you are doing.

Some users report difficulty achieving a solid 100% charge indicator, with the unit showing a blinking charge light instead of solid. I experienced this during testing as well. The unit appears to function normally despite the indicator behavior, but it is something NOCO should address in future firmware or design updates.

Who Should Buy the NOCO GBX75

This is the right choice for truck owners with mid-size engines who want faster charging than the GB150 offers. If you have a 5.3L or 6.2L gas engine and want the NOCO brand reliability with modern USB-C charging, the GBX75 hits the sweet spot.

Who Should Skip It

If you need maximum power for large diesels, the GBX155 is a better investment. Quality concerns about post-2020 production units also give me pause about recommending this over the proven GB150 for users who prioritize reliability over charging speed.

What to Consider When Buying a Jump Starter for Your Truck

Choosing the right jump starter requires understanding several key factors that affect performance and usability. Here is what our testing revealed matters most for truck owners.

Understanding Peak Amps vs Cold Cranking Amps

Peak amps represent the maximum current a jump starter can deliver for a brief moment, typically 1-2 seconds. Cold cranking amps (CCA) measure sustained output over 30 seconds at 0 degrees Fahrenheit. For trucks, look for peak amps of at least 1500A for gas engines and 2000A+ for diesels.

The reality is more complex. A 2000A lithium unit might outperform a 2000A lead-acid unit because lithium batteries maintain voltage better under load. During testing, I saw the NOCO GB70 (2000A lithium) out-crank a competitor’s 2500A lead-acid unit on the same truck.

Engine Size and Amp Requirements

Here is a practical guide based on our testing:

For 4-cylinder and 6-cylinder gas engines in light trucks, 1000-1500A is sufficient. V8 gas engines need 1500-2500A depending on displacement. Small diesel engines (3.0L-5.9L) need 2000-3000A. Large diesels (6.0L-7.3L) require 3000A minimum, with 4000A+ recommended for cold weather.

Dual-battery diesel trucks present a special challenge. The batteries are wired in parallel, which means the jump starter must overcome the resistance of both battery banks. For these applications, you need the highest amperage available: the GOOLOO GT Truck PRO or NOCO GBX155 at minimum.

Lithium-Ion vs Sealed Lead Acid

Lithium-ion jump starters are lighter, charge faster, and hold their charge longer between uses. A lithium unit might weigh 3-7 pounds versus 18-40 pounds for lead-acid equivalents. They also include modern features like USB charging and LED displays.

Sealed lead-acid (SLA) units deliver more sustained cranking power and handle deep discharges better. For commercial use, repeated daily starting, or extremely cold climates, SLA units like the Clore JNC660 provide more reliable long-term performance. They are also more tolerant of being left in sub-optimal charge states.

Cable Length and Clamp Quality

Truck batteries are often located in difficult positions: under the hood on one side, under the cab, or in the bed. Short cables force you to position the jump starter awkwardly or leave it hanging from the clamps. Look for at least 24-inch cables, with 40+ inches preferred for full-size trucks.

Clamp quality determines how well the unit connects to corroded or odd-sized terminals. Professional-grade units use copper-alloy clamps with strong springs that maintain contact pressure. Cheap units often use thin steel clamps that flex and lose contact under load.

Safety Features to Look For

Reverse polarity protection prevents damage if you accidentally connect positive to negative. All quality units have this, but implementation varies. The best units like NOCO and Clore models completely block power flow when reversed. Cheaper units may just beep a warning.

Spark-proof technology prevents arcing when connecting to the battery. This matters more than you might think: a spark near a charging battery or fuel vapor can be dangerous. Look for units that suppress sparks during connection.

Over-current and thermal protection prevent the unit from damaging itself or your vehicle if something goes wrong. These features are standard on lithium units but worth verifying on any model you consider.

Additional Features Worth Considering

USB charging ports turn your jump starter into a power bank for devices. The 60W USB-C PD ports on newer models can even charge laptops. LED flashlights with SOS modes provide emergency lighting. Air compressors, like those on the DEWALT unit, add versatility for tire inflation.

Boost mode (also called force start) allows the unit to power a battery that reads below 2 volts. Without this feature, many jump starters cannot detect a completely dead battery and will not deliver power. For trucks with parasitic drains or old batteries, boost mode is essential.

How to Jump Start a Truck with a Portable Jump Starter

Using a jump starter correctly ensures safety and success. Follow this proven procedure our team has refined through hundreds of test starts.

Step-by-Step Guide

First, turn off all electrical accessories in your truck: lights, radio, AC, and anything else drawing power. Connect the red (positive) clamp to the positive battery terminal or the remote jump-start post if your truck has one. Connect the black (negative) clamp to an unpainted metal surface on the engine block or chassis, away from the battery.

Turn on the jump starter and wait for any status lights to indicate readiness. Most units show a green light or solid indicator when properly connected. Attempt to start your truck. If it does not start immediately, wait 30 seconds between attempts to let the jump starter cool down.

Once the engine starts, let it run for at least 15-20 minutes to recharge the battery. Disconnect the clamps in reverse order: black first, then red. Recharge your jump starter as soon as possible so it is ready for next time.

When to Use Boost Mode

Boost mode (also called manual override or force start) is necessary when your truck battery is completely dead, reading below 2 volts. Most jump starters cannot detect such low voltage and will beep or flash an error instead of delivering power.

To use boost mode, connect the clamps as normal, then press and hold the boost button (or power button on some models) for 3-5 seconds. This overrides the safety detection and forces power delivery. Use this mode only when necessary, as it bypasses some safety protections.

Safety Precautions

Always wear eye protection when working with batteries. Batteries can vent explosive hydrogen gas, especially when charging or severely discharged. Never smoke or create sparks near a battery. If the battery case is cracked or leaking, do not attempt to jump start: replace the battery instead.

Keep the jump starter away from moving engine parts like belts and fans. The cables can get caught and damage the unit or your truck. If you smell rotten eggs (sulfur), see the battery swelling, or notice extreme heat, stop immediately and call for professional help.
