Cell size reference
Electrical characteristics
(typical values relative to cells stored for one year or less at +30ºC max.)
Nominal capacity
(at 1.0 A +20ºC 2.0 V cut-off. The capacity restored by the cell varies
according to current drain, temperature and cut-off)

Maximum recommended continuous current
(to avoid over-heating)
Pulse capability: Typically up to 5 A.
(The voltage readings may vary according to the pulse characteristics,
the temperature and the cell’s previous history. Fitting the cell with a
capacitor may be recommended in severe conditions. Consult Saft)
