Specification of ER18505M Li-SOCl2 Cylindrical Battery

Electrical characteristicsOpen circuit voltage (at 25°C)≥3.65V
Nominal capacity3500mAh
(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 current600mA
(At +25°C, 2.0V cut-off, battery discharged for a minimum of 50% of nominal capacity. )
Maximum pulse discharge current1200mA
(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 characteristicsDiameter18.7±0.3mm
Typical weight32.0g
Li metal content1.01g
