Key features
l
Pulse capability: Typically up to 300 mA
(300 mA/0.1 second pulses, drained every 2 mn at + 20°C from undischarged cells with 10 µA
base current, yield voltage readings above 3.0 V. The 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
(Higher currents possible, consult Saft)
Storage
