Why won't my I-Mark battery stay charged?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care to learn more about the state of your battery.

What do you do with my dead I-Mark battery?

What’s the cost of DieHard batteries for Isuzu I-Marks?

You can find affordable I-Mark batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.

How often should I replace my car battery?

Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.

Why is there white, flaky stuff around my I-Mark’s battery post?

The white, flaky stuff that can build up around your I-Mark’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your I-Mark, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I clean a corroded I-Mark battery terminal?

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 I-Mark owner’s manual for instructions on how to do so.
