Buying Guide

These are the factors that you need to consider when buying a car or trailer winch battery:


You can’t just use any battery for your winch. You need to find one that is compatible with your winch. The first thing you need to check is the specific battery requirement of your equipment. Furthermore, you also need to purchase one that is compatible with your car. That way, you’ll have no issues with how you would mount or carry the battery.

Battery Chemistry

The two types of batteries based on their chemistry are lead-acid and Absorbed Glass Mat (AGM). AGM is more expensive but they have better recharging cycles and can withstand regular draining.

Lead acid batteries are more budget-friendly but they generally do not perform as well as AGM.

Reserve Capacity

The reserve capacity of a battery will tell you how long when fully charged it will last to provide you with 25 amperes of power at 80°F. Having a long reserve capacity will obviously be advantageous.

But don’t buy anything with less than 100 minutes of reserve capacity for your winch. 

Cold Cranking Amps (CCA)

Winch batteries come with cold cranking amps or CCA rating that will give you an idea of how well a battery works under freezing conditions.

More specifically, it signifies the number of amperes a lead-acid battery can deliver for 30 seconds at 0°F. For a winch that weighs 13,000 pounds, it is best to get a battery with at least 650 CCA.

Batteries with high CCA also makes a good starting battery for your car.

Amp Hours (AH)

AH indicates the amount of charge or power that a battery can provide. A battery that offers 80 AH for 15 hours will give you 5.3 amps (80 divided by 15) of current continuously for 15 hours.  

Weight and Dimensions

You can get an idea of the size of a winch battery by merely looking at its group. For electric winches, batteries that belong to group 31 or 48 are a good size in general.

Spill Protection

You don’t want the toxic materials inside the battery to spill. Make sure to get a battery that is spill-proof and leak-proof for your safety.


As electric winch batteries aren’t inexpensive, getting one with a long product warranty can give you peace of mind in case the battery will not work as it should.

Some batteries offer up to 3 years of warranty which covers replacements while others may have a shorter warranty period.

Conclusion and Buyers Advice

Performance-wise, our top choice is the Optima Batteries OPT8003-151 8003-151 34R. It is spill proof, resistant to vibration and it works even under bad weather. It is also a clean and consistent power source.

Moreover, it happens to be one of the lightest winch batteries on our list.
