What is the Average Lifespan of a Jeep Wrangler Battery?

Assuming you are talking about the Jeep Wrangler JK, which was produced from 2007-2018: The average lifespan of a Jeep Wrangler battery is approximately five years where Nixon watch battery lasts two years. However, this can vary depending on a number of factors, such as how often the vehicle is used, the climate in which it is driven (hot weather can shorten the lifespan of a battery), and how well the battery is maintained.

There are a few things you can do to help extend the life of your Jeep Wrangler’s battery:

Keep It Clean

Dirt and grime can build up on the terminals and lead to corrosion, which will eventually cause problems with starting or charging the battery. Regularly cleaning the terminals will help prevent this.

Keep It Charged

If you let your Wrangler’s battery run too low, it will shorten its lifespan. Try to keep it above 12 volts; 14 volts is even better. You can use a voltmeter to check the voltage of your battery; most auto parts stores will also test batteries for free.

Avoid Short Trips

Starting and stopping the engine uses up power, so if you’re only going for a quick drive around town, your battery won’t have time to fully recharge itself between uses. Longer trips are better for keeping your battery healthy.

Use a Trickle Charger

Use a trickle charger when you’re not using your Jeep Wrangler for extended periods of time (like over winter).

This will help maintain its charge and prevent sulfation (a buildup of lead sulfate crystals on the plates inside the battery that reduces its ability to hold a charge).
