WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The amp hour rating of a battery is the amount of time it takes a fully charged battery, being discharged at a constant rate of 1 amperes and a constant temperature of 27 °C (80 °F), to reach a terminal voltage of 10.5 volts. Refer to BATTERY USAGE for the amp hour rating of the original equipment battery.
