How to keep your Jeep Grand Cherokee battery healthy

Replacing a Jeep Grand Cherokee battery can cost several hundred dollars, but there are a few steps that you can take to keep your vehicle’s battery in tip-top condition for as long as possible.

In addition to performing regular battery tests, here’s how to care for your car battery:

Start and drive your car on a regular basis: When you drive your vehicle, the battery is recharged by the engine. Therefore, cars that sit around for a long time will experience battery depletion. Generally, about 15 minutes of driving is enough to charge your battery!

Manually recharge the battery if your car has been sitting for a long time: For example, if your car is parked for over a week while you’re on vacation, using a manual battery charger can increase its efficacy and overall lifespan.

Don’t leave your lights on: When the engine isn’t running, leaving on your headlights or interior lights can drain your car’s battery quite quickly.

Disconnect electronics when not in use: Charging your iPhone is perfectly safe when your car is running and the engine is on. Once you turn your vehicle off, however, you should unplug all cords.

Perform essential vehicle maintenance: Other issues with your car’s electrical system, for example, can cause battery depletion, so don’t neglect necessary maintenance or repairs.
