How to Measure Battery Capacity

The formula for determining the capacity of a lead-acid battery is: Capacity (Ah) = (RC / 2) + 16 For example, if a lead-acid battery has a reserve capacity of 120 minutes, its capacity would be: Capacity (Ah) = (120 / 2) + 16 = 76Ah It is important to note that the capacity of a lead-acid battery decreases as the temperature drops.

How to Store a Lead-Acid Battery
