The
MW-5798 has two independent charging banks.
One bank is located on the left side of the charger and the second
bank is located on the right side of the charger.
The two banks are separated by 2 slots for charging 9V type NiMH or
NiCD batteries in the middle of the charger.
Charging
AA, AAA, C, or D Size Batteries.
You can
automatically charge any two AA, AAA, C, or D size NiMH /NiCD batteries in
each of the two outside banks as long as you follow the instructions
below:
- Both
batteries placed in each bank must be of the same type and capacity.
You cannot mix battery types and capacities in each individual
bank. You can however
charge different sizes of batteries in each separate bank.
For instance you can charge AA batteries in bank one while
charging AAA, C, or even D batteries in bank two, etc….
Two batteries are required in each bank.
·
While the batteries are charging the LED indicators on the front of
the charger will glow RED. Once
the batteries have completed their charge cycle the same LED indicators
will glow GREEN denoting that the batteries are now on trickle charge and
that the batteries have completed their charge cycle.
You may leave the batteries on trickle for an added topping off
charge or just to maintain them in a fully charged state until you need
them. Please note that you
should not leave your batteries in the charger once you have unplugged the
unit This will cause the batteries to discharge.
So if you unplug your charger be sure to remove the batteries.
Charging 9V Size NiMH / NiCD
Batteries
The
MW-5798 PRO is designed to charge up to two 9 volt NiMH or NiCD batteries
at a time.
Insert
your 9V battery into either 9V battery slot being careful to match the
proper connector on the charger to the connector on your battery.
Once the 9V battery is properly inserted the LED indicator in front
of the 9V slot will glow RED while the battery is charging.
The 9V charging cycle is not automatic and you will need to remove
your 9V battery once the battery has been fully charged depending on your
calculation.
Below
is an example on how to calculate 9V charging times.
Example:
Your 9V battery is rated at 160 mAh and the MW-5798 PRO charges 9V
batteries at a constant 13 mA pulse rate.
So to calculate your charge time you will divide your 160mAh
battery capacity by the 13 mA charge rate and the result will be
approximately 12.5 hours. So
to be assured of a full charge you should allow 13-14 hours.
Please not that it is safe to allow the 9V NiMH batteries to charge
up to 20 hours or more without any overcharging concerns.
Separate
color LEDs to indicate charging status of each bank.

Battery Information
All New
NiMH batteries require charging before their first use.
Batteries are not shipped charged, however some may have a small
amount of charge from the factory.
NiMH
rechargeable batteries usually require at least 3 to 5 uses before they
will be at full potential and capacity.
By uses we mean the actual charge and discharge cycle as you
normally use them in your equipment.
Do Not fully charge your batteries and then discharge the fully
charged batteries in your charger. Just
use them as you normally will. Basically
you are breaking them in to your equipment and the more you use them the
better they function. So do
not be alarmed if the first few times you charge and use NEW NiMH
batteries they seem to discharge quicker than expected.
