Bosch BAT645 and BAT690 Battery Chargers

By means of the new BAT645 and BAT690 battery chargers, Bosch offers automotive workshops two universally applicable professional devices featuring 45 or 90 ampere of continuous current output. Automatically detecting the required nominal voltage, both chargers can be used for 12-volt car batteries and 24-volt commercial vehicle batteries alike.

As additional modes of operations, BAT 645 and BAT 690 feature both a back-up and a buffer mode. At the back-up mode, the device ensures the vehicle’s power supply in case the starter battery has been removed. The buffer mode, on the other hand, is of increasing importance in everyday workshop life. In this case, the battery charger supports the on-board power supply, for instance, in case of control unit updates.

The new battery chargers are equipped with a USB port easing software updates. This allows, for instance, uploading characteristics for innovative types of batteries – thus keeping the devices up to date at any time. In addition, a WiFi connection is planned for BAT 690 in order to enable its future integration into workshop networks.

Product Features

  • 45 A or 90 A – universal battery chargers for all lead ac-id battery types (standard, maintenance-free, gel, fleece, AGM, EFB) and new Li-Ion – Lithium Iron Phosphate (LFP)
  • 12 V / 24 V for cars and trucks with automatic selection
  • Fully automatic charging characteristics – Universal for all battery types (UNI) and specific characteristics for WET, AGM, GEL, EFB and LFP and soft charging phase for deeply discharged batteries (automatic)
