MH-C801D

Eight Cell One Hour Charger

Thank you for purchasing the PowerEx MH-C801D
battery charger. Read these instructions carefully and
thoroughly before operating this unit. IMPORTANT
SAFETY INSTRUCTIONS. READ AND SAVE THESE
INSTRUCTIONS.

VARIOUS MODES

This section explains various charging modes and when to use them. To
enable each mode, refer to the “Operation” section.

Rapid Charge Mode (Default)

GENERAL PRECAUTIONS

• Do not charge battery cells other than NiMH or NiCD. AA Batteries
must be able to accept a 2.0A (Rapid mode) / 1.0A (Soft mode) rapid
charge current. AAA Batteries must be able to accept a 0.7A (Rapid) /

0.35A (Soft) rapid charge current.

• Do not use one-hour rapid charge mode on AA batteries rated under
2000mAh and AAA batteries under 700mAh. To charge them, use the
Soft Charging mode (refer to “Soft Charging Mode”).

• Do not expose the unit to rain or moisture due to the risk of fire.

• Do not operate the charger if it appears damaged in any way.

• Always place the battery cells with positive tip facing the top. Incorrect

polarity may cause fire or explosion. Observe polarity diagrams located
on the charger.

• Do not allow the unit to be exposed to direct sunlight. Operate in well-
ventilated area.

• Do not allow the battery terminals to become shorted.

• To reduce the risk of damage to the power cord, always pull by

connector rather than the cord.

FEATURES & SPECIFICATIONS

• Eight independent charging slots. Charges 1-8 AA or AAA batteries.

• Selectable Rapid Charge and Soft Charge mode.

• Recharges in approximately 1 hour.

• Selectable conditioning / rejuvenation cycle.

• Worldwide power supply.

• Shortest recharging time (approximately one hour).

• Suitable for AA batteries with capacity greater than 2000mAh and

AAA with capacity greater than 700mAh.

Soft Charging Mode

• Maximizes battery life and performance (recharging time
approximately two hours).

• Suitable for most batteries.

• Recommended if recharging time is not critical.

Conditioning Mode

• A special mode which rejuvenates and cycles batteries. Applies a
special initial charge, discharge and recharge cycle which
restores battery performance (requires up to 14 hours to
complete).

• Conditioning cycle can be used to rescue degraded batteries and
exercise infrequently-used batteries.

• Recommended once every ten normal charges for NiMH batteries
to ensure performance.

OPERATION

Rapid Charge Mode (Default)

1. Connect the supplied power cord to the power supply unit and connect
to a compatible outlet (100-240VAC, 50/60Hz). Connect the DIN
connector to the charger unit as shown in the figure below.

TIP: When operating the charger outside of its intended region of use,
simply obtain a power cord with a suitable plug type or use a plug­changer. Transformer is not necessary.

2. Insert AA and/or AAA batteries. ALWAYS INSERT THE BATTERIES
FROM LEF T TO RIGHT LEAVING NO EMPTY SL OT.

For best performance, group batteries of similar charge and/or type
together (e.g. 2500mAh AA batteries in slot 1, 2, 3, 4 and 1800mAh

AA batteries in slot 5, 6 and 700mAh AAA batteries in slot 7, 8).

NOTE: Ensure that the batteries are pressed down all the way to
ensure optimal contact.

Soft Charging Mode

NOTE: Soft Charging is activated for all battery slots simultaneously and
cannot be activated for each individual battery.

1. Remove all batteries from the charger, if any.

2. Insert one battery in the leftmost slot.

3. Within five seconds, press and hold the “SOFT” button until “Soft
Charging” symbol is displayed on the LCD screen.

The figures below show possible configurations for battery placement.

3. When the battery is corr e ct ly inser t e d , cha r g in g w ill commence for that
slot. The charger is equipped with a four-level battery gauge which
displays the charging progress.

Extremely low charge. Typically indicates
abnormal or aged batteries. Conditioning is
recommended.

Flashing

4. Insert the remaining batteries from left to right leaving no empty slot.

5. Soft Charging mode will remain activated as long as there are batteries
in the charger (even if charging is completed). The charger will reset to
Rapid Charge mode (Soft Charging symbols disappears) when all
batteries are removed.

Conditioning Mode

NOTE: Conditioning is activated for all battery slots simultaneously and
cannot be activated for each individual battery.

1. Remove all batteries from the charger, if any.

2. Insert one battery in the leftmost slot.

3. Within five seconds, press and hold the “CONDITION” button until
”Condition” symbol is displayed on the LCD screen.

TIP: If Conditioning and Soft Charging is desired simultaneously, insert
the first battery, press the Soft Charging button first followed
immediately by the Conditioning button. THIS CAN TAKE UP TO 35

HOURS TO COMPLETE.

4. Insert the remaining batteries from left to right leaving no empty slot.

5. The condition cycle will first apply an initial charge, discharge then
recharge the batteries.
