Cadmium – nickel battery charging process, with the charge to the battery voltage increases, when the voltage exceeds 1.55V, the electrolyte water electrolysis, precipitation of gas, reduce the charging efficiency, charging efficiency of 85 normal % of. Cadmium – nickel battery charge voltage and charging mechanisms. The greater the charge current, charge voltage higher charge temperature is higher, take out the lower electric voltage.

Cadmium – nickel battery discharge curve is more flat, generally 0.2C5A current discharge, discharge voltage stabilized at around 1.2V. Discharge capacity and quality of active material, electrolyte concentration, discharge temperature, discharge current and discharge mechanism and so on.

At low temperatures, electrolyte solution, electrical conductivity decreases, viscosity and concentration polarization becomes larger, the battery’s internal resistance increases, the battery’s capacity has been reduced. HP ProBook 4311s battery Cadmium – nickel battery discharge performance at low temperature are still better than the other battery. At high temperatures, the conductivity of electrolyte solution increases, viscosity decreases, the battery discharge capacity increases, but when the temperature Gao at 501: time, good efficiency down to positive charging, the battery performance degradation.
