Why won’t my RX battery hold a charge?

A battery is in its final hour when it will no longer hold a charge. It may be getting old. Or, you may have a habit of leaving your car doors open and the cabin light at night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.

What do you do with my old RX battery?

What’s the cost of DieHard batteries for Subaru RXs?

Subaru RX 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?

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 RX’s battery post?

The white, flaky stuff that can build up around your RX’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 RX, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

What do I do about corrosion on my RX car 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.
