The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation Ni–Cd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd): the abbreviation NiCad is a registered trademark of SAFT Corporation, although this brand name is commonly used to describe all
Customer ServiceNi-Cd cells are most commonly used in battery packs. In using Ni-Cd batteries, the type of battery, the number of cells, the shape of the battery pack, and the components of the battery pack will be determined by the ratings (voltage and load current) of the device, the charging specifications, the amount
Charging is done using 1.6 times the voltage in the charging circuit. Normally, NiCd batteries are charged 300 to 800 times, with the capacity dropping to approximately 80% after 500 charges and discharges. The memory effect of NiCd batteries is more severe than that of NiMH batteries.
• The standard charge method for Ni-Cd batteries. The charger construction is simple and inexpensive. If the specific conditions of the device require that a charge rate higher than 0.1 CmA be used, the overcharge performance and temperature rise characteristics will vary according to the battery type.
If a NiCd battery is not fully discharged and recharged during use, the next time it is discharged, it will not be able to discharge the full charge. For example, if the battery is fully charged again after 80% discharge, the battery can only discharge 80% of its charge. This is the so-called memory effect.
Some would consider the near-constant voltage a drawback as it makes it difficult to detect when the battery charge is low. Ni–Cd batteries used to replace 9 V batteries usually only have six cells, for a terminal voltage of 7.2 volts.
One of the most remarkable problems associated with a Ni–Cd battery is based on their high cost due to expensive cadmium and nickel materials used in the construction. Environmental constraint is most likely encountered using the battery on the circumstance that the heavy metallic materials used are not well disposed-off.
