Plochingen, Germany – With its new BAT 6120, Bosch is offering vehicle workshops a universally usable device that can serve both as a smart and fast charger for 12-volt lead and lithium batteries and as a power source providing up to 120 amperes of continuous current. Its compact design makes the battery charger suitable for mobile use on a trolley, a bench or the floor. The BAT 6120 can also be mounted on a wall or placed under a vehicle.

Safe battery charging, stable power supply

With its different operating modes, Bosch’s new BAT 6120 can be used very flexibly, thus satisfying the requirements of modern vehicle workshops. All kinds of 12-volt lead-acid batteries, whether wet-cell, AGM, EFB or gel batteries, are charged fully automatically and safely. Lithium iron phosphate (LFP) batteries can also be charged quickly and intelligently. The BAT 6120 also supports modern battery management systems and features a wake-up function.

In power source mode, it supplies up to 120 amperes of continuous current. This means, it can be used for a highly dynamic power supply to modern vehicles during flashing and calibration processes. The maximum power output is 1750 watts. Output can be limited manually.
In battery replacement mode, the new battery charger helps simplify the process of changing the battery. In showroom mode, the BAT 6120 serves as a high-performance power source. Situated unobtrusively beneath the vehicle, it provides the vehicle with electricity reliably, quietly and fully automatically.

The BAT 6120 can be operated simply and intuitively by four buttons next to the 3’’ LCD display. The display screen’s four different types of background colors which are used in different operating modes. In addition, the display can be turned 180 degrees for wall mounting. The screen can also display a QR code which users can scan for easy access to the website of the BAT 6120 help center, where they can read operating instructions and tips for use.
