Typically recommended with low mileage vehicle use. Ampere is a unit of measure for current flow through a conductor or circuit. 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. 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.
Batteries come in many different group sizes and terminal configurations.
The industry assigns letters and numbers for common battery size types.
