12 volt battery charger with capacity preselection for starter batteries of all types (lead acid, lead calcium, maintenance-free lead gel batteries). Suitable for batteries from 3 to 300 Ah.
Maximum charge current: 70 amperes arithmetic for at least 30 sec. at 12.0 volts
Steady output:
62 amperes arithmetic at 12.4 volts
50 amperes arithmetic at 14.4 volts

Modes of operation: Electronically controlled full charge as per IU map with charge retention; FSV power supply for vehicle electrical system support during diagnosis work (e.g. flashing control units, also on 10 and 12-cylinder engines). Buffer charging of batteries with consumers activated (showroom operation and vehicle presentation), support operation of vehicle electrical systems without starter battery (steady voltage in event of battery change or ancillary test without battery). Top-up charge of heavily discharged batteries (de-sulfating charge) maintenance charge for permanent backup operation (e.g. during winter).
Automatic current draw check in accordance with Volkswagen Group inspection instruction for starter batteries in connection with warranty claims.

Equipment safety:
Polarity reversal protection with start inhibitor
Short circuit protection
No sparks generated from terminal contact
Overload protection with fuse
Charge voltage free of voltage peaks
Absolute safety for airbag and onboard electrics
Exchangeable, screw connected charge cable with heavy duty charge clamps
