ER18505 Datasheet

ctrical characteristics

Open circuit voltage (at 25°C)


Nominal capacity


(At +25°C, the battery is discharged at continuous current 2mA until the voltage reaches cut-off voltage 2.0V. The capacity can vary at a different temperature, discharge current or cut-off voltage.)

Maximum continuous current


(New cell*, at +25°C, 2.0V cut-off, battery discharged for

minimum 50% of nominal capacity.)

Maximum pulse discharge current


(200 mA/0.1 second pulses, drained every 2 minutes at +25°C from undischarged the new cell with 10 uA base current, yield voltage reading above 3.0V. The readings may vary according to the pulse characteristics, the temperature, and the’s previous history. Fitting the cell with a capacitor may be recommended in severe conditions, consult HCB.)

Storage (recommended)


(For more severe conditions, consult HCB)


Operating temperature range


(Operation above ambient temperature may lead to reduced

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