WorkshopCharger 25A

Flexible charger for workshops

Flexible and easy to use quality battery charger with practical solutions and every function needed in the workshop.

Item no: 706900


WorkshopCharger 25A is portable, durable and user-friendly. It features modern Switch-Mode technology, has excellent efficiency, and uses a temperature compensated charging cycle that protects sensitive electronic systems and battery performance.

We’ve designed the charger with a 3-meter cable, a wall bracket, a place to hang the coiled cable and an isolated hook.


When you need continuous current and stable voltage during ECU programming or battery replacement, you can use our workshop chargers as a power supply. Activate Powersupply-mode by holding the “ON” button until the display begins to light up in sequence.


WorkshopCharger 25A is well suited for battery sizes up to approximately 500Ah. It can maintenance charge batteries indefinitely and handle parallel consumption up to 30A while charging. The charging voltage is temperature compensated with an external sensor

14,7 V with WorkshopCharger 25A

Some batteries require a higher charging voltage than others (this is described son the battery). Press the 14.7V button, and the initial charging voltage will be 0.3V above than the standard level.
