1.2V +70C HRHT23/43 Ni-MH SC Rechargeable Battery 3000mAh

Specifications

1.2V +70C HRHT23/43 Ni-MH SC Rechargeable Battery 3000mAh

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 -40°C~+70°C

High temperature

Features:

1. Excellent charge and discharge performance at high temperature, even at the temperature of 35°C-70 °C, it still has very high charging efficiency.
2. Long service life and high reliability, more than 500 cycles of charge and discharge.
3. Very good over-charge resistance performance, no damage to battery under long time charge with 0.05C current at temperature of 70 °C.

Application:

Emergency light, Sign lights, Emergency lighting, fire alarm system. Solar street lamps, lawn lamp, highlight hand torch, police electric batons, high temperature environment instruments and meters, portable instrument etc.
