BATTERY CHARGER WITH BATTERY CHEMISTRY AND VOLTAGE IDENTIFICATION

摘要

Cordless power tools 25 may be powered by batteries having a lithium-based chemistry, which require precise charging schemes and controlled discharge. A battery of the invention has a lithium-based chemistry, a nominal voltage in a nominal voltage range, identification components indicative of chemistry and nominal voltage or nominal voltage range, and operable with an electrical device which can identify the chemistry and nominal voltage or nominal voltage range of the battery.
