Cell size reference
Electrical characteristics
(Typical values relative to cells stored for one year or less
at + 30°C max.)
Nominal capacity
(at 250 mA + 20°C 2.0 V cut-off. The capacity restored by the
cell varies according to current drain, temperature and cut-off).
Open circuit voltage (at + 20°C)
Nominal voltage (under 1 mA at + 20°C)
Pulse capability : Typically up to 8 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.)
Maximum recommended continuous current
(To maintain cell heating within safe limits)
Storage (recommended)
(for more severe conditions, consult Saft)
Operating temperature range
(Operation below ambient T may lead to reduced capacity and
lower voltage readings)
