BU-407: Charging Nickel-cadmium
BU-407: Charging Nickel-cadmium. Nickel-based batteries are more complex to charge than Li-ion and lead acid. Lithium- and lead-based systems are charged with a regulated current to bring the voltage to a set limit after which the battery saturates until fully charged. This method is called constant current constant voltage (CCCV).

The fully charged voltage on 10 NiCd batteries is about 1.4V * 10 = 14V. So the first thing you will need is a voltage source higher than that. To keep it safe you really need 1.5 * 10 = 15V minimum. ... So a discharged battery at 1.1V will charge at (18 - 11) / 100 = 70mA. This current will fall to 40mA as the battery comes up to full charge.
