(Note) The above characteristics data are average values obtained within three charge/discharge. Cycles not the minimum values. (Note) This battery is designed for high rate discharge and we do not specify 20 hour rate discharge capacity. (Note) When specific conditions are satisfied, this battery can be used for main power supplies. Please consult Panasonic.
