If you have a first-generation Jeep Compass (model years 2007 to 2016), its battery group code is BCI (Battery Council International) 86. However, 2017 to 2023 models have DIN (German Industrial Standard) battery group codes of H6 or H5, depending on whether or not the vehicle has start/stop technology.

A car’s battery will usually last about three to five years, depending on usage. So if your vehicle is older, you’ve likely had to replace the battery at some point. And if it’s a couple of years old, you may be due for a new battery soon!

Let’s go through what you need to know to find a battery that fits and discuss what sorts of options you have when replacing your Jeep Compass battery.

How big is a Jeep Compass battery?

You’ve probably already noticed that not every

Jeep

uses the same battery. In fact, not even every Jeep Compass has the same battery.

The easiest way to figure out what kind of battery will fit in your particular model is to look at your handy-dandy owner’s manual. What gifts of information are contained within this oft-elusive volume?!

Don’t have your manual? Try popping the hood and taking a look at the battery itself. The battery label will usually include both its size and cold cranking amps (CCA).

Jeep Compass battery life

The battery in a conventional engine vehicle is recharged by converting mechanical energy back to potential electric energy. This means your battery is recharged by the engine as you drive.

That being said, the more you use a rechargeable battery, the weaker it gets. You’ve probably noticed this phenomenon if you kept the same smartphone for a long time. Because of this, your car battery should be changed every four to five years, depending on how often you drive and what kinds of conditions you're driving and storing your car in.

If you want to get a clear picture of your car’s battery life, you can regularly test it to avoid battery-related breakdowns. It’s also a good idea to look out for these signs of battery failure:

Clicking sounds at vehicle startup

Corrosion on the outside of the battery, often near the terminals

Frequently needing to

jump/charge

Dim headlights or other electronics not working as they used to

How to keep your Jeep Compass battery healthy

Regular tests are a good place to start, but there are more things that you can do to extend the life of your Jeep’s battery:

Regularly drive your car. Since driving is what recharges your battery, vehicles that stay parked for a long time will often slowly lose juice to whatever components are sipping battery power while it’s not in use.

Manually recharge the battery after your Jeep has been in storage. If you leave your Jeep in your garage during a two-week vacation, consider taking the battery out and charging it before the next time you start it up.

Don’t leave your lights on. This will quickly drain the battery!

Disconnect electronics when you turn your car off. If you have chargers or other devices plugged into your Compass’ electrical sources, they might drain battery power even when the car’s engine is off.

Keep up with regular maintenance. A variety of vehicle issues can lead to battery life depletion. Sticking to your manufacturer's recommended

car maintenance schedule

is a great way to avoid these issues.
