EN · machine-assisted draft

A lead-acid battery rating expressed in minutes under a specified discharge test. Gerry’s FAQ describes a 25-amp load at 80 °F until a 12-volt battery reaches 10.5 volts. It is neither amp-hours nor a prediction of camper runtime, which depends on actual loads, conditions and discharge limits.

Compare reserve-capacity ratings under the same test conditions.
