Abstract
Method for charging a sealed storage cell battery according to which the battery is heated when its temperature lies below a determined value and the intensity of the charge current is lowered by being shunted to heat the battery when the voltage of the battery reaches a given value, characterized in that the said value of the voltage of the battery supplies the signal which causes the heating of the battery; and device for implementing the method.
