A method in charging a battery powered device (10) having a built-in charge control circuit (13) controlled by the device, and an apparatus for working the method, including said device. The device including the battery (11) is connected to a battery charger (17), and initially when the battery voltage is too low to initiate normal charging of the battery over the charge control circuit, the battery is connected to the battery charger via a current generator (25) which is switched off when the battery voltage has increased to a level which is high enough to support normal charging of the battery over the charge control circuit.

[ What is claimed is:] [1.]1. A method of charging a battery powered device from a battery charger, said device having a built-in charge control circuit, controlled by the device and operatively connected to a battery in the device, the method comprising:comparing a battery voltage of the battery with a predetermined reference voltage;when said battery voltage is lower than said reference voltage, charging said device from said battery charger via a current generator until the battery voltage has reached the reference voltage; andwhen or after the battery voltage has reached the reference voltage, switching off said current generator and charging the battery over the charge control circuit so that charging continues but now over the charge control circuit.
