GENERAL PRECAUTIONS

Do not charge battery cells other than NiMH or NiCD. AA
batteries must be able to accept a 1000mA (Turbo Mode)
/ 500mA (Default Mode) charge current. AAA Batteries
must be able to accept a 500mA (Turbo Mode) / 250mA
(Default Mode) charge current.

Do not use the 2 hour Turbo Mode on AA batteries rated
under 2000mAh and AAA batteries under 700mAh. To
charge them, use the Default Mode (refer to "Default
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.

MODES
This section explains various charging modes and when to use
them. To enable each mode, refer to the "Operation" section.
Default Mode

Soft charge to maximize battery life and
performance. Recharging time is approximately 4-6
hours.
NOTE: Time may vary depending on battery
capacity and how much charge is remaining in the
battery.

Suitable for most NiMH or NiCD batteries.

Recommended if recharging time is not critical.
Turbo Mode

Faster recharging time. Charges twice as fast as the
Default Mode, approximately 2-3 hours.

Recommended for AA NiMH batteries with capacity
of at least 2000mAh and AAA NiMH with capacity of
at least 700mAh.
Conditioning Mode

Rescues degraded batteries and exercise
infrequently used batteries.

Rejuvenates and cycles the batteries. It applies a
special conditioning cycle which restores battery
performance. Requires up to 48 hours to complete
the cycle.

Actual capacity will be displayed at the end of the
conditioning cycle.

Recommended every 6 months or once a year to
ensure battery performance.
OPERATION
Default Mode
1. Plug the power connector to the charger first then plug
the AC adapter into the wall outlet.
2. Insert AA and/or AAA batteries. For best performance,
insert the batteries from the left to right.
3. Once the battery is inserted, charging will commence for
that slot. Each slot number will start flashing indicating it's
charging.
The displayed mAh value represents the amount of
energy that was charged into the battery. It is NOT
the actual capacity of the battery.
4. Charging time will take approximately 4-6 hours.
Once a battery is done charging, the slot number will stop
flashing and remain solid. The charger will display DONE
for each channel that is done charging. The charged
battery may be removed for use.
The displayed mAh value represents the amount of
energy that was charged into the battery. It is NOT
the actual capacity of the battery.
