Why won’t my NX300h battery hold a charge?

A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop in for a free battery check at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

How long is a car battery good for?

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

What is the white, crusty stuff around my NX300h’s battery post?

The white, flaky stuff that can build up around your NX300h’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 NX300h, 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 corrosion off my NX300h vehicle battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
