Why won't my Trooper battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a free battery test at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

What do you do with my dead Trooper battery?

What’s the cost of DieHard batteries for Isuzu Troopers?

Isuzu Trooper batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.

How often should I replace my car battery?

A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.

Why is there white, flaky stuff around my Trooper’s battery post?

The white, crusty stuff that can accumulate around Trooper car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

How do I remove corrosion from my Trooper car battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your Trooper owner’s manual for instructions on how to do so.
