rated capacity (lead-acid): The capacity assigned to a cell by its manufacturer for a given discharge rate, at a specified electrolyte temperature and specific gravity, to a given end-of-discharge voltage. service test: A test of a battery''s capability, in an "as-found" condition, to satisfy the battery duty cycle.
Temperature vs. Capacity
Cooler ambient temperatures will reduce battery capacity, but cycle life is improved. Note: Cycle life loss of ~50% is expected for every 10˚C over 25˚C (77˚F) When operating in cold temperatures the capacity of the battery bank must increase to achieve an actual equivalent AH capacity. Rated AH capacity is at 25˚C (77˚F).
