How long will the MH-C777PLUS II take to charge my battery packs?
The charging time, which is different for each battery pack, is determined by dividing the capacity of the battery pack by the charging current. The capacity is given in “milliamp ere hours” and is generally found on the battery label. Take this number and divide it by the MH-C777PLUS II charging current, which are 800mAh for NiMH & NiCD batteries and 400mA for Lithium Ion battery pack. The resulting value is the approximate number of hours needed to quick charge the battery pack. The charging time will be reduced if the battery is not fully discharged.
