Charge property

 

The voltage of Ni-Cd and Ni-MH battery goes up during charging, and at charging terminal stage, as battery inner temperature rising, the voltage will fall down and finally reach to balance state. The battery is normally charged at constant current for a defined time: 0.1C₅A for 14-16 hours, 0.2 C₅A for 7 hrs, 0.3 C₅A for 4.5hrs, 0.5 C₅A for 2.5 hrs, 1 C₅A for 1.2hrs (Please contact with us if the designed charge current is over 0.5 C₅A, C₅ is battery capacity)

 

Discharge property

 

Discharge capacity changes according to discharge current. The smaller discharge current, the more capacity be discharged, vise versa. The capacity is also influenced by environmental temperature and the end voltage. The rated capacity means the capacity when battery is discharged at 0.2 C₅A to end voltage of 0.1V/cell at the environmental temperature of 20°C±5°C

 

Cycle life property

 

As the working conditions and environmental is different, it is difficult to show batteries accurate service life. Under normal condition, it is expected to be 500-1000 cycles.

 

Discharge temperature property

Discharge conditions: single cell discharged at 0.C to 1.0V.

Suitable temperature range for discharge is -20°C~+70°C

Separate Ni-Cd Batteries when shipping to prevent short circuits.

All the battery are packed in strong cartob case.
