Lithium Battery CR14250SE Advantages

High voltage response, stable during most of the lifetime of the application

Energy density of CR14250SE 3V lithium battery up to 830Wh/L

As one of the primary lithium battery suppliers china, we provide the battery with wide operating temperature range (-40℃~+85℃)

Low self-discharge rate for primary lithium battery CR14250SE (less than 1% per year after 1 year of storage at +25℃)

CR14250SE Datasheet
Electrical characteristicsOpen circuit voltage (at 25°C)≥3.10V
Nominal capacity900mAh
(At +25°C, the battery is discharged at continuous current 0.5mA 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 current7mA
(At +25°C, 2.0V cut-off, battery discharged for minimum 50% of rated capacity.)
Maximum pulse discharge current70mA
(At +25°C, 2.0V cut-off, battery discharged for minimum 50% of rated 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-40°C~+85°C
(Operation above ambient temperature may lead to reduced capacity and lower voltage readings at the beginning of pulses, consult HCB.)
