## **Electrical characteristics**
_(typical values relative to cells stored for one year or less at + 30°C max.)_
|Nominal capacity||7.7 Ah|
|---|---|---|
|_(at 4 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)|3.67 V|
|Nominal voltage|(at 0.5 mA + 20°C)|3.6 V|
|Nominal energy||27.72 Wh|
## 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|||150 mA|

## **Storage**
- l The storage area should be clean, cool _(preferably not exceeding + 30°C),_ dry and ventilated.
## **Warning**
- l Fire, explosion and severe burn hazard.
- l Do not recharge, short circuit, crush, disassemble, heat above 100°C _(212°F),_ incinerate, or expose contents to water.
- l Do not solder directly to the cell _(use tabbed cell versions instead)._
