Nickel-Cadmium Battery ChargingDecember 7th Fact-of-the-Day
Nickel-cadmium (NiCd) batteries can be recharged approximately 800 times over a period of 3 to 5 years if they are properly charged on each charge cycle. However, few nickel-cadmium batteries last that long, because of poorly designed battery chargers that continue to supply charging current after batteries are charged. Nickel-cadmium batteries are permanently damaged if that happens. It is easy to tell whether charging current stops after charging, because batteries left in a charger after charging will remain hot or warm to the touch if current continues to flow. ©2004 Martek, International.
