Portable, durable, user-friendly. Upgrade your workshop with the “all in one” automated charger and power supply unit that is the size of book. The DEFA WorkShopCharger 35A is a powerful charger that can be used with all 12V WET, MF, Ca/Ca, AGM, EFB and GEL batteries.  It’s designed to easily and safely charge and maintain battery size up to 600Ah.

It features modern switchmode technology, galvanic isolation, a temperature compensated charging cycle and excellent efficiency. This protects sensitive electronics and improves the performance and lifetime of the battery. WorkShopChargers can also recondition degenerated batteries with automatically controlled software.

When you need continuous current and stable voltage during ECU Programming and/or battery change, the DEFA WorkShopCharger 35A can be used as a power supply.

Multiple sensors ensures that the correct battery temperature is maintained and that the optimal charging curve is used to maximize battery charge and performance.

WorkShopCharger 35A is supplied with a 3 meter cable, a wall bracket and an isolated hook for extra convenient use and storage.

Powersupply mode

Powersupply mode is activated when pressing and holding the on button until the LED’s in the display begins to light up in a bottom to top sequence.
