BAT 690 – battery charger

BAT 690
BAT 690 Detail

The universal BAT 690 is designed to charge all battery types, including; lead-acid, maintenance-free, standard, gel, fleece, AGM, EFB and Lithium Iron Phosphate (LFP) batteries. Using its soft charging phase, the BAT 690 can automatically charge heavily-depleted batteries.

Featuring as standard, both a backup mode, maintaining voltage supply to buffer data during battery replacement (e.g. car stereos, supply and control units, etc.) and floating mode, to keep the SOC of the battery and stabilise the vehicle’s electrical system when the engine is off. In floating mode, the battery charger can support the on-board power supply during any control unit updates.
