What is Reserve Capacity vs Amp Hours (AH) on a Battery?

While RC rating is a measurement of time, an amp hour rating is the measurement of how many amps the battery can provide in one hour. Reserve capacity is measured in minutes, whereas amp hours are measured in amps per hour. To convert reserve capacity to amp hours (AH), one must divide the reserve capacity by 60 and multiply the result by 25.
