Designing and building the best military chargers for over 25 years.

NiCd charger

CL331The CL331 battery charger is made for professional use indoors. The charging process is fully automatic and utilises a patented charging technology. The charging voltage is continually adjusted depending on the behaviour of the connected battery. Different parameters influences the charging process i.e. the battery temperature, the age of the battery, state of charge, manufacture etc. The intelligent charging technology, that allows charging of batteries with different voltages and capacities, makes it simple to manufacture new battery adapters that fit into the front connector.
