Unlike old 9V battery chargers, the MH-C490F charger can charge one to four 8.4V and 9.6V batteries within 2 hours. No more waiting overnight to have the batteries fully charged. Perfect for instant power on the go! The MH-C490F is an intelligent charger featuring the Delta-V based microprocessor which allows your batteries to be charged to their full potential. The microprocessor automatically switches from rapid charge to trickle charge after the batteries are finished charging, so that the batteries will maintain their full capacity. And, unlike those other chargers claiming to be able to charge 9V batteries in the car, the MH-C490F has a patented automatic step-up device that is capable of providing a full, complete charge to your batteries. 9.6V NiMH batteries need a minimum of 15V input voltage to charge the battery to its full potential. The compact 2.5″ x 3″ size of this charger means you can put it just about anywhere.
