New to the UK: Bosch BAT 645 and BAT 690 battery chargers
24 January 2018 
The new BAT 645 and 690 battery chargers from Bosch feature 45 or 90 amperes of continuous current output. They are suitable for conventional lead-acid and gel batteries, as well as absorbent glass mat (AGM) and enhanced flooded battery (EFB) technologies and lithium-ion LiFEPP04 (LFP) batteries. When the tool identifies an ‘exhausted’ or empty battery, the battery chargers use a specific setting to maximise battery life. Using back-up mode, the devices ensure a stable power supply even when the starter battery has been removed. Meanwhile, buffer mode supports on-board power supply during control unit updates.
