Charging Batteries with Different
Capacities
The charger can be used to recharge Ni-Cd
batteries with capacities greater than 850
mAh and Ni-MH batteries with capacities
greater than 1600 mAh. Simply reset the
charger to begin a second charge cycle for
batteries with larger capacities. For batteries
with less capacity, simply remove batteries
before the charge cycle is complete, based on
estimated charge times in the following chart.
AA 1600 13 hr., 10 min.
AAA 180 3 hr., 35 min.
AAA 550 11 hr.
AAA 600 12 hr.
Batteries will not be damaged by leav-
Note:
ing them in the charger until the timer turns it
off.
To calculate the charge time for your battery,
based on its rated capacity, use the following
formulas.
•
For AA batteries:
Charge time in hours =
the capacity of your battery × .0082
•
For AAA batteries:
Charge time in hours
= the capacity of your battery × .02
