Plug in the charger to the supplied AC adapter to turn the unit on. The power
input must be 5 V with at least 4 A of current capability. Each battery may take
up to 2 A while charging.
Simply slide a battery into either battery slot to begin charging. The adjacent
charge indicator will illuminate yellow when charging is in progress. The
charge indicator will change to green when charging is complete.
Charger slots are completely independent so a battery may be inserted
regardless of the state of the other battery slot.
Charging may take 2-4 hours if the battery was normally discharged.
Charging may take up to 5 hours with a completely drained battery which has
been stored for several months without use.
By design Li-Ion batteries should not be charged above 40 °C-45 °C so a
blinking charge light may mean the batteries are too hot for charging. Charging
will resume after the batteries cool down. The charging time will be longer due
to the batteries cool down when charging batteries above 40 °C-45 °C.
