What does discharge power mean in a battery?
(Discharge Rate) The discharge power of a battery is the amount of power that the battery can deliver over a certain period of time. The discharge power rating is usually expressed in amperes (A) or watts (W). The higher the discharge rate, the more power the battery can deliver. Batteries are one of the most important inventions of our time.
What is an example of a battery discharge rate?
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. The battery discharge rate is the amount of current that a battery can provide in a given time.
What is battery discharge efficiency?
