WorkshopCharger 35A

Flexible charger for workshops

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

Art. nr: 707200


WorkshopCharger 35A 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. WorkshopCharger 35A can also recondition degraded batteries with automatically controlled software.

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 35A is well suited for battery sizes up to approximately 600Ah. 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

14,7V with WorkshopCharger 35A

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

Technical description

WorkShopchargers are compatible with all 12V WET, Ca/Ca, AGM, EFB and GEL batteries.
