Main applications
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)
Storage
(recommended)
(possible without leakage)
+ 30°C (+ 86°F) max
+ 85°C (+ 185°F) max
- 60°C/+ 70°C
(- 76°F/+158°F)
Operating temperature range
(Operation above ambient T may lead to reduced capacity and lower
voltage readings at the beginning of pulses. Consult Saft)
