OPERATING INSTRUCTIONS

An automatic charger designed to 
charge both normal and maintenance-
free 6 V / 12 V starter batteries (lead-
acid accumulators) as well as AGM / 
lead-acid (MF, VRLA) batteries used in 
cars.
The charger is controlled by a 
microprocessor which, when the 
accumulator is charged, switches the 
charger automatically into a charged 
mode where the microprocessor 
maintains targeted charging without 
overcharging or damaging the 
accumulator.
In order to ensure safe and proper use 
of the charger, this manual must be 
thoroughly studied before use.
