Abstract:
A method for charging batteries, particularly in cordless communication devices, said method comprising the steps of:inserting at least one battery into a device for a first time;after said insertion, during an initial charging phase, fully charging said battery;after said full charging, at least partially discharging said battery;generating at each point in time a value representing a capacity drawn up to said partial discharging;after said partial discharge, given a start of a renewed charging phase, comparing said generated value to a stored base value representing a duration of said initial charging phase; andafter said comparison, during subsequent charging phases following said initial charging phase, at least partially charging said battery when said generated value is one of less than or equal to said base value and when said generated value that, over and above this, is stored as a new base value when said generated value is higher than said base value hitherto stored and said batteries have a fully charged condition at a beginning of a discharge phase leading to said generated value.
