Applying power
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.
Charging the battery
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.
Take note of the following:
• Charger slots are completely independent so a battery may be inserted
regardless of what is occurring in 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.
