Abstract
The present invention relates to a method for operating a battery charger, and a battery charger. The method comprising the steps of determining a capacity of the battery, determining an initial charging current, apply the calculated initial charging current as a charging current to the battery, determining the voltage change with time ΔV/Δt for the voltage over the battery, adjusting the charging current based on the ΔV/Δt.
