Your Jeep Wrangler battery size depends on its year and configuration. There are five different options:
12 3/8" x 6 7/8" x 7 1/2"
12 1/16" x 6 7/8" x 7 9/16"
10 1/4" x 6 13/16" x 7 7/8"
10 1/16" x 7 3/16" x 6 15/16"
Installing the correct Wrangler battery size is not only a matter of performance but of safety. Because every vehicle requires different amounts of power to run properly, if your battery is too small, your car won’t start. On the other hand, if the battery is too large, you risk fire and other hazards.

The Jeep Wrangler has six possible battery group codes: H7, H6, 34/78, 34, 58, or 56. See the chart above to determine your Wrangler battery group code.
Jeep Wrangler battery lifespan
How often should you change your Jeep Wrangler battery? Most car batteries will function at full capacity for around three years. That may seem short—and you’re right. You can usually squeeze a lot more life out of your battery, but unfortunately, you’ll probably notice a dip in your battery’s performance after three years.
Keep an eye out for these signs that it’s time to change your Wrangler battery:
You’re having difficulty starting your car
The Check Engine light is on
There’s a foul smell (like rotten eggs)
Electrical issues (like unresponsive power windows)
Struggling in cold temperatures
If your Wrangler has any of these problems, it may be time for a new battery!
