Applications: Electronic devices, Video cameras, Measurement devices, Emergency lighting, Communication, Toys etc.

Charging: Standard charging will be accomplished in 0.1C for 14-16 hours. Fast charging will be accomplished in 0.3-1C for 2-7 hours.  In order to properly charge batteries, it is recommended to use chargers that suit all the demands and safety measures required by the cell manufacturer.

Discharging: Nominal capacity is defined according to the capacity received by discharging 0.2C for 5 hours in 20°C temp when the cell voltage in the end of the discharging process reaches 1V. Ni-Cd cells are capable of discharging in continuous current to 3C.
