Even a maintenance-free battery needs a little TLC. Here are a few things you can do:
To start, always be certain the ignition switch is in the OFF position before cleaning or servicing your battery. Then:
- If you see any corrosion on the battery, remove the cables from the terminals (wear rubber gloves - battery acid is nasty stuff and can damage your skin). Clean the terminals with a wire brush.
- To clean, apply a thick solution of baking soda and water to the affected areas on post and/or terminals to neutralize the acid. Let it bubble for a few minutes, then wipe off the excess.
- Replace cables and tighten. Add a bit of grease to the top of each terminal for protection against future corrosion. If applicable, replace the battery cover.
- Important: Some preset engine control conditions (such as idle) may need to be reset if battery power is interrupted. Be certain to consult your vehicle owner's guide for the correct procedure.
What do these common battery phrases mean?- Amp: Ampere is a unit of measure for current flow through a conductor or circuit.
- Cold Cranking Amps (CCA): Indicates strength of battery. This rating is the discharge load, in amps, which a new, fully charged battery at 0 degrees Fahrenheit can continuously deliver for 30 seconds while maintaining terminal voltage equal to or higher than 1.2 volts per cell.
- Reserve Capacity (RC): Indicates the stamina of the battery. The number of minutes a new, fully charged battery at 80 degrees Fahrenheit can be continuously discharged at 25 amperes while maintaining a terminal voltage equal to or higher than 1.75 volts per cell.
- Group Size: Batteries come in many different group sizes and terminal configurations. The industry assigns letters and numbers for common battery size types. For example: all group size 24 batteries have the same container dimensions and features, orientation location, and terminal type.
