Intelligent NiCd Charger Avoids Battery Damage From High Currents

Focus:

When fast charging a NiCd battery, the high charging current raise the temperature and pressure within the NiCd cells, potentially resulting in damage or destruction of the battery. To protect the battery, a charging circuit monitors the temperature differential between the battery's surface and the ambient and reduces charging current as the temperature differential increases.
