Battery charger with self-compensating device and alarm light indicator characterized by the fact that it is provided with a fixed and calibrated resistance interspersed in the low voltage circuit between the transformer and the rectifier plates connected in parallel with a pilot lamp whose resistance is it achieves self-regulation of the load current since an increase of said current is compensated and therefore reduced by the voltage drop that it causes in the resistance by varying the luminous intensity of said pilot lamp in direct function of the load current.
