1. A charging method for batteries comprising:
- a first phase being a constant current charging up to a given value of a battery voltage U; and
a second phase in which the battery voltage U is limited as a function of a charging current iL, the following relationship existing between the battery voltage U and the charging current iL ;

UwhereinUo =current-independent part of the battery voltage U,Δ
U=current-dependent part of the battery voltage U

U=f·
i.sub.L ·
R.sub.i withf=factor smaller than 1iL =charging currentRi =internal resistance of the battery.
