Instruction Manual

INTRODUCTION:

Congratulations on purchasing this intelligent charging unit which enables def initely quick and optimum charging to “AA” and “AAA” rechargeable batteries. With charging, discharging, refreshing and capacity test functions as well as individual LCD displays for charging compartments; this charging unit is reliable, user-friendly and ideal for use in the home, office or on journey.

The Charging unit

CAUTIONS:

1. The charger is restricted to charging NiCd and NiMH rechargeable batteries only. Never adopt this charger to other types of batteries such as alkaline, lithium, carbon zinc or other types that are not specified.

2. The charging unit shall only be used only at normal indoor room conditions.

3. Always follow the charging instructions for the rechargeable battery. Observe the recommended charging current of the rechargeable batteries. Never adopt a charging current higher than recommended in the charging process.

4. Never use any power cable and transformer other than those originally supplied with the charging unit.

5. The rechargeable batteries may become hot during charging (especially when high charging current is chosen). User shall take extra care when taking out the batteries after charging.

6. Unplug the charging unit from the power source when not in use.

FEATURES:

The Charging unit

z Charging the rechargeable battery in various current value (200, 500 or 700 mA) z Individual LCD display for compartments z Charging both “AA” and “AAA” rechargeable batteries simultaneously z Overheat detection to protect rechargeable batteries from over-charging

z Minus delta voltage (-dV) detection for charge termination z Damaged batteries detection z Discharge mode (first discharging and then charging) to remove memory effect of

rechargeable batteries

z Refreshing old rechargeable batteries by discharging/ charging cycles z Test function to check the capacities of rechargeable batteries z Different Charging/ Discharging functions can be launched independently and

simultaneously to each rechargeable battery in the compartments

z Various display modes during charging/ discharging – the charging current (in mA), time

elapsed (in hh:mm), the terminal voltage (in V) and accumulated capacities (in mAh or Ah)

FUNCTION KEYS:

There are three easy-to-use function keys and four number keys in the charging unit:

CURRENT key

Compartment Number key

Press and release the Number key to select a particular battery compartment for charge modes and/or display mode adjustment.

MODE key

The mode key shall first be pressed and held for about 1 second to activate the mode change. The subsequent pressing of the mode key will enable to toggle between the “Charge”, “Discharge”, “Test” and “Refresh” mode. To change the operating mode for individual rechargeable battery, first press corresponding NUMBER key then press the MODE key.

DISPLAY

Compartment Number keys

MODE key

DISPLAY key

Press and release to select the displays of the charging current (in mA), time elapsed (in hh:mm), the terminal voltage (in V) and accumulated capacities (in mAh or Ah) during the charging or discharging process. To change the display content of a particular rechargeable battery, first press corresponding NUMBER key then press the DISPLAY key.

CURRENT key

Press to select the amount of current to be applied (within the first 8 seconds after batteries are inserted) in different operating modes (also see “Start charging the rechargeable batteries” below).

OPERATING MODES OF THE CHARGING UNIT

This powerful charging unit provides the following operating modes: a. Charge up the rechargeable battery (CHARGE) – to charge up the rechargeable

battery, automatically switch to trickle charge after rechargeable battery is full.

b. Discharge then charge up the rechargeable battery (DISCHARGE) – to discharge the

rechargeable battery then charge it for minimizing the memory effect.

c. Refresh the rechargeable battery (REFRESH) – to refresh the rechargeable battery to

its maximum capacity by charging and discharging the rechargeable battery repeatedly until no further increase in the capacity is estimated. For old rechargeable batteries or

those have not been used for a long times, refreshing may bring the rechargeable battery back to the optimum condition.

d. Check the rechargeable battery capacity in mAh/ Ah (TEST)

CHARGE MODE

Charging at 200 mA is the default-operating mode of the charging unit. User may select a charging current of 200, 500 or 700 mA.

The estimated time of charging by various charging current is tabulated in Table 1.

Table 1. Charging Time with various charging current

Size of battery Battery Capacity Charging current selected (mA) Estimated charging time

AA 2500 mAh

AAA 700 mAh

700 ~3 hr 35 min 500 ~5 hr 200 ~13 hr 700 ~60 min 500 ~84 min 200 ~3 hr 30 min

Note:

z User shall always observe the recommended maximum charging current of the

rechargeable batteries. In general, 200 mA is a recommended charging current if rapid charging is not necessary. It is definitely safe and optimum to the rechargeable batteries.

z It may be necessary to charge and discharge the new rechargeable batteries for several

times in the beginning before the optimum capacity of the rechargeable batteries can be obtained. And user is recommended to adopt once the "Refresh" mode to the new rechargeable batteries in order to achieve the optimum battery capacity.

z When the transformer has been plugged to the power source, the version number of the

charger (for example “29” ) will be displayed first. Then all the segments will light up momentarily and the “null” sign will be shown before batteries are placed. If damaged batteries are placed to the charging unit, the charger will also show “null” on LCD.

“null” displayed - No battery or damaged battery is placed to the charging unit
