The Jeep Wrangler is about as capable an off-road vehicle as is sold today. Such a versatile vehicle affords owners the opportunities to do things and go places most vehicles would never dare. If you're taking your Jeep Wrangler as far off the grid as possible or even if you don't crawl anywhere besides malls, you still want the best battery for it that you can get. Many newer Jeep Wranglers, including Jeep Gladiators use a Group 48 or H6 battery and OPTIMA offers a direct-fit H6 YELLOWTOP battery to fit in these applications. With 928 cranking amps on tap, these batteries offer more than enough starting power for any Jeep with the added bonus of plenty of reserve capacity and the ability to be deep-cycled. Another popular battery in newer Jeeps is the Group 94R or H7 battery and OPTIMA also offers a direct-fit H7 YELLOWTOP battery to fit in these applications. The OPTIMA H7 is even larger and more powerful!

That means you can hook up a winch, a big stereo, extra lights and more and the OPTIMA H6 or H7 YELLOWTOP will hold up it's end of the deal. OPTIMA batteries also feature a sealed design, so if your Jeep gets sideways or even upside down, your battery won't spill acid. The cast straps made with 99.9% pure virgin lead are unique to the OPTIMA H6 & H7, which allows them to accept more current and recharge faster than batteries that use more traditional "tombstone welds" to connect their cells. These durable batteries can last up to three times as long as a traditional flooded battery, which means you spend less of your valuable time worrying about replacing your battery. Plus, if you buy factory-direct and buy a Digital 1200 Charger at the same time, we'll even add a year of coverage to your warranty.

However, the biggest challenge for Jeep Wrangler owners in selecting a new battery may be figuring out which one they need between the H6 and H7. The BCI fitment guide has 25 different variations for Jeep Wranglers, just between the model years 2012 to 2021! We'll try to simplify it for you here.

2012-2015
H6 was the go-to battery from 2012 to 2015 model year Jeep Wranglers.

2016-2017
The H6 was still the standard battery in 2016 and 2017, but the H7 was an option. If your battery isn't clearly-labeled indicating which size you have, this video will help you figure out which one is which between an H6 & H7.

2018-2021
The 2018 model year is where things started to get complicated. The H7 is still the standard battery for the 3.6-liter V6, but the 2.0-liter engine was also an option and later, a 3.0-liter V6 came along. The bottom line is, if your Jeep Wrangler has start/stop (the engine shuts off at stoplights & starts up when you press on the gas like a golf cart), then the H6 is your battery. If it doesn't have start/stop, then the H7 is your battery.

It's also worth noting that start/stop Jeep Wranglers also came with a smaller, auxiliary battery, either a Group 400 or Group 401, for which OPTIMA does not currently offer.
