Reserve capacity minutes:

Reserve capacity minutes refer to the minimum current the battery must continuously deliver 25 amperes before its voltage drops below 10.5 volts. If the volts drop below 10.5 volts during the reserve capacity the battery should be charged. When a battery drops below 10.5 volts the plates can be damaged.
