Why won't my SC430 battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. It may be getting old. Or, you may have been leaving your car doors ajar and the dome lights on during the night.

What do you do with my dead SC430 battery?

What’s the cost of DieHard batteries for Lexus SC430s?

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 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.

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?

Regularly inspecting and cleaning your battery terminals will help keep your SC430’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
