The Einhell CE-BC 4 M battery charger is an intelligent system with a multi-stage charging cycle that is microprocessor-controlled and suitable for all common 12 V vehicle batteries. The maintenance charge function preserves the battery being charged and extends its lifespan, particularly in the case of seasonally used vehicles. The Reconditioning mode allows for the regeneration of deeply discharged batteries. With protection against overcharging, short circuits, and reverse polarity, along with a dust and splash-proof case equipped with a suspension eyelet, the device is completely safe. The charger also features fully insulated battery clamps. The LCD indicator for battery voltage and charging progress allows you to quickly see the battery's status at a glance.
