Nominal capacity 1.20 Ah (at 1 mA + 20°C 2.0 V cut-off. The capacity restored by the battery varies according to current drain, temperature and cut-off) Open circuit voltage (at + 20°C) 3.67 V Nominal voltage (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.) Maximum recommended continuous current (Higher currents are possible, consult Saft) Storage (recommended) (for more severe conditions, consult Saft) Operating temperature range (Operation above ambient T may lead to reduced capacity and lower voltage readings at the beginning of pulses. Consult Saft) 35 mA + 30°C (+ 86°F) max - 60°C/+ 85°C (- 76°F/+ 185°F) 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 LS 14250 MLB battery Voltage plateau versus Current and Temperature (at mid-discharge) 3.6 +70°C Cell voltage (V) 3.5 + 20°C 3.4 3.3 3.2 3.1 3.0 - 20°C 2.9 2.8 2.7 - 40°C 2.6 2.5 0.01 0.1 1 10 100 Current (mA) Typical discharge profiles at + 20°C 3.7 3.5 3.1 2.3 Dimensions in mm. 2.1 7.5 kOhms/0.5 mA 2.5 3 kOhms/1.2 mA 2.7 400 Ohms/8.5 mA 2.9 56 Ohms/54 mA Cell voltage (V) 3.3 1.9 1 0.1 10 100 1000 10000 Time (hours) Storage Warning • Fire, explosion and burn hazard. • Do not recharge, short circuit, crush, disassemble, heat above 100°C (212°F), incinerate, or expose contents to water.
