(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, therefore 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.
