Specification of ER18505M Li-SOCl2 Cylindrical Battery

Electrical characteristics Open circuit voltage (at 25°C) ≥3.65V

Nominal capacity 3500mAh

(At +25°C, the battery is discharged at a continuous current of 6mA until the voltage reaches a cut-off voltage of 2.0V. The capacity can vary at different temperatures, discharge current or cut-off voltage. )

Maximum continuous current 600mA

(At +25°C, 2.0V cut-off, battery discharged for a minimum of 50% of nominal capacity. )

Maximum pulse discharge current 1200mA

(At +25°C, 2.0V cut-off, battery discharged for a minimum of 50% of nominal capacity with max pulse for 3 seconds after 27 seconds break. The discharged capacity 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 HCB.)

Storage (recommended) ≤+30°C

(For more severe conditions, consult HCB) ≤75%RH

Operating temperature range -55°C~+85°C

(Operation above ambient temperature may lead to reduced

capacity and lower voltage readings at the beginning of pulses, consult HCB.)

Physical characteristics Diameter 18.7±0.3mm
