  •  How long do car batteries 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 S4’s battery post? The white, flaky stuff that can build up around your S4’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.

If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • How do I clean a corroded S4 battery terminal? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your S4 owner's manual to learn how to disconnect the battery cables.
