## **Electrical characteristics** 

|**Electrical characteristics**||
|---|---|
|_(typical values relative to batteries stored for one year or less at + 30°C max.)_||
|Nominal capacity|1.20 Ah|
|_(at 1 mA + 20°C  2.0 V cut-off. The capacity restored by the battery varies_<br>_according to current drain, temperature and cut-off)_||
|Open circuit voltage<br>(at + 20°C)|3.67 V|
|Nominal voltage<br>(at 0.1 mA +20°C)|3.6 V|



Pulse capability: Typically up to 100 mA _(100 mA/0.1 second pulses, drained every 2 mn at + 20°C from undischarged battery 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 battery previous history.)_ 

|_battery previous history.)_||
|---|---|
|Maximum recommended continuous current|35 mA|
|_(Higher currents are possible, consult Saft)_||
|Storage<br>(recommended)|+ 30°C (+ 86°F) max|
|(for more severe conditions, consult Saft)||
|Operating temperature range|- 60°C/+ 85°C|
|_(Operation above ambient T may lead to reduced capacity and_|(- 76°F/+185°F)|
|_lower voltage readings at the beginning of pulses. Consult Saft)_||



## **Main applications** 

- [ Utility metering] 

- [ Automatic meter reading] 

- [ Alarms and security devices] 

- [ Memory back-up] 

|**Physical characteristics**||
|---|---|
|Diameter (max)|16.8 mm (0.66 in)|
|Height (max)|28.6 mm (1.12 in)|
|Typical weight|15 g (0.5 oz)|
|Li metal content|approx. 0.3 g|
