ABSTRACT:
The invention relates to a method for terminating the charging of a battery, in which a certain decrease in the battery voltage is detected when the battery is fully charged and the charge begins to decrease. With the invention it is possible to prevent battery overcharge reliably and efficiently. The solution can be applied to the charging of both Ni--Cd and Ni--MH batteries with a same charger and/or same charge control program.
