Why won’t my SC430 battery hold a charge?

A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead SC430 battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

How much do DieHard batteries cost for your Lexus SC430?

Lexus SC430 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 long can I expect my car battery to last?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

What is the white, crusty substance accumulating on my SC430’s battery post?

If you notice white, crusty stuff around the battery terminals of your SC430, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your SC430’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my SC430 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 SC430 owner’s manual for instructions on how to do so.
