The battery discharge rate is the amount of current that a battery can provide in a given time. It is usually expressed in amperes (A) or milliamperes (mA). The higher the discharge rate, the more power the battery can provide. To calculate the battery discharge rate, you need to know the capacity of the battery and the voltage.
Making Sense of Battery Ratings
Another test to determine ratings is called a Reserve Capacity test. It basically counts the number of minutes a fully charge battery will discharge at a 25A draw before the battery is "dead." Oh, and improperly draining a lead acid battery to dead usually damages the battery enough that you''ll need to replace it.
