WebIt’s important to understand the difference between amp-hours (Ah) and reserve capacity (RC). Although they are similar, they aren’t quite the same thing. Reserve capacity is a term that makes note of how many minutes a battery can hold a voltage without going below 10.5 volts. This is usually used for automotive purposes. Keep in mind ... WebMay 7, 2024 · How do you calculate reserve capacity? Reserve Capacity is usually the number of minutes a battery can deliver at a ’25-amp rate’ so multiply the number of minutes by 25A (and divide by 60) and you have a measure of Ah (@25A). Amp Hours is usually the number of Ah a battery can deliver at the ’20-hour rate’.
