Nickel Cadmium Batteries Technical Handbook ''05/''06
• Discharge batteries within an ambient tempera-ture range of -20°C to +65°C. • Discharge current level (i.e. the current at which a battery is discharged) affects discharg-ing efficiency. Discharging efficiency is good within a current range of 0.1 CmA to 0.5 CmA. • Discharge capacity drops at temperatures below -20°C or above +65°C.

The variations on charge are caused by the current ic, which is defined as the different between the overall current introduced or extracted from the battery and the self-discharge current. Thus, the capacitor voltage, V SOC, coincides with the SOC. Due to neglecting self-discharge losses, the current ic coincides with i (ic = i-isd).
