It’s tough, trail-tested, and plain cool. I’m talking about the Jeep Wrangler. While it may be a timeless beast, I can’t say the same about its lead-acid battery. Eventually, it will need replacing especially if you want to maintain deep cycling for demanding off-road handling.
I’ve put together five of the best batteries for the Jeep Wrangler. These are well-researched batteries that tick all the right boxes to fit your specific model and comfortably run your accessories.
The Jeep Wrangler is one of the most amazing SUVs to take on any adventure. Whether you want to crawl over rocks in summer or maintain a straight line in the snow, the Jeep Wrangler can do it all.
When it comes to finding the most reliable battery for the Jeep Wrangler, there are a few things that I deem essential.
1. Size/Group Size
The group size determines the battery size for your specific Jeep Wrangler. It is set by the LxWxH of the battery and the terminal locations. These specifications will help you choose a battery that fits in the space allocated for the battery and the correct terminals for your vehicle.
2. Weight
While the weight of the battery does not affect its performance, you are better off with a lightweight option. When it comes the time to remove it in winter, you will not hurl out a super heavy battery.
3. Power
Power is an essential consideration since Jeep Wranglers are high-performance vehicles. You will need a battery with enough power to crank the engine, provide deep cycling, and cater to your off-roading demands.
4. Safety
It’s vital that you check out the construction quality of your vehicle’s engine. This is due to the chemical reactions within the battery that can emit dangerous emissions. It’s best to go for a well-constructed battery to prevent any leaks.
5. CCA Rating
CCA stands for Cold Cranking Amps. It is the standard rating for the power that the battery will output to start your Jeep in cold temperatures. This number is significant if you live in a cold climate. To this end, your Jeep Wrangler battery should match or exceed the recommended CCA rating for your generation.
6. Recharge Time
A battery with a short recharge time is preferable over one with a long recharge time. Nonetheless, keep in mind that batteries with lots of power take longer to recharge than those with a lower capacity.
7. Vibration Resistance
Vibration can kill your car’s battery just as fast as chronic overcharging. That’s why you should go for a battery that showcases vibration resistance to prevent cracks in the cell separators and connectors when you take your Jeep Wrangler on rough roads.

8. Maintenance
Will you have time to maintain your battery, let alone remember to do it? While some brands may have you thinking that it’s an easy job, a maintenance-free battery is the best option for your Jeep Wrangler. All you need is to install it, connect the terminals, and forget about it.
9. Reserve Capacity
The reserve capacity tells you how long your new and fully recharged battery can power your Jeep Wrangler’s accessories if the alternator fails. Particularly, it shows the average minutes that the battery delivers 25 amps constant current at 80°F without falling to 1.75 volts per cell, the minimum voltage.
A long reserve capacity can save you if your alternator fails outdoors since you can drive a long distance without the engine stalling.
