How do you calculate battery discharge rate?
The faster a battery can discharge, the higher its discharge rate. To calculate a battery's discharge rate, simply divide the battery's capacity (measured in amp-hours) by its discharge time (measured in hours). For example, if a battery has a capacity of 3 amp-hours and can be discharged in 1 hour, its discharge rate would be 3 amps.
