LCD displays for the 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 battery or

other types of battery that is not specified.

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

conditions.

3. Always follow the charging instructions for the rechargeable

battery. Observe the recommended charging current of the

rechargeable batteries.

4. Never use other kinds of the power cable and transformer apart

from those originally supplied with the charging unit.

5. The rechargeable battery may become hot during charging. User

should take extra care when taking out the battery after charging.

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

use.

OPERATING STAGES OF THE CHARGING UNIT

The charge stage and the trickle charging are the only two operating

stages of this charging unit.

CHARGE STAGE

The unit can charge up the rechargeable battery. It will automatically

switch to trickle charging after the rechargeable battery is fully charged.

During the process of charging, the display of voltage and percentage

will alternate on the LCD. The item of percentage will show the

percentage of the battery charged while the item of voltage will show the

voltage of battery. Once the battery is full, the voltage will display

permanently with the “Full” sign. The trickle charging will start shortly

afterwards.

Charging current that is around 250mA is the only default value in the

charging process.

The estimated charging time of different battery size is tabulated in

Table 1.

charging time

AA 2600mAh

12 hrs

AAA 1000mAh

around 250mA

6 hrs

“--” displays - No battery is placed to the

charging unit (figure 1)

Note:



It may be necessary to charge and discharge the new

rechargeable batteries for several times in the beginning in order

to obtain the optimum capacity of the rechargeable batteries.

However, this charger does not provide the discharge function.

Users may need to discharge the new rechargeable batteries

themselves.



When the transformer has been plugged to the power source, the

version number of the charger (for example “14” ) will display

after all the segments light up momentarily. The “--” sign (figure 1)

will show before the batteries are placed. If the defect batteries

are placed to the charging unit, the “DEF“ sign (figure 2) will show

on the LCD of charger.



The “DEF” sign will flash for a while on the LCD when the charger

detects the battery condition. When the defective condition of the

battery is confirmed, the “DEF” sign will turn on permanently.



If attempting to recharge the alkaline or carbon batteries, it may

cause rupture, explosion or the leakage of hazardous liquids.



During the charging process, the “Charge” sign will show if any

rechargeable batteries are placed into the unit. Users should

make sure that the charged batteries are either NiCd or NiMH

type and should not use the alkaline or carbon batteries.



Carbon or Alkaline batteries may be the cause of the defect.

Those types of batteries are NOT suitable for this charger.

Another defect cause may come from the rechargeable batteries

which voltage is too low.

TRICKLE CHARGING

After the rechargeable battery is fully charged, the charger will give a

small amount of current to the rechargeable batteries to maintain the

fully charged level. This stage is automatically launched after

rechargeable batteries are fully charged and kept at the charging unit.

The “Full” sign will display on the LCD.

“DEF” displays – A defect battery is

placed into the charging unit (figure 2)

START CHARGING THE RECHARGEABLE BATTERIES

After the transformer has been plugged to

the power source, user should insert a

rechargeable battery into the charging unit

and plug the DC jack into the battery

charger. Shortly afterwards, the battery

voltage (for example, “1.38V”) will display.

Then the “Charge” sign will show on LCD

within 5 seconds, indicating that the

charging process with around 250mA is

going to start.

During charging, terminal voltage (in V)

(figure 3) and percentage (in %) (figure 4)

are the two items that will alternate to show

on the LCD.

(Figure 4)

After the rechargeable battery is fully charged, “Full” sign (figure 5) will

show on the display and the user may take them out at this time. Or if

the rechargeable batteries are kept placing at the compartments, trickle

charging will start. The trickle charging current is around 10% duty cycle

of the charging current to keep the rechargeable batteries full.

Note :



The charging current of the rechargeable batteries depends on

battery condition. It cannot be selected by the user.



In case the power source terminates, the charger will reset. Once

the power source is back to normal, the batteries will be taken as

newly installed batteries in the charger.

“Full” sign shows -

For proper reset, unplug the DC jack and wait for 5 seconds

before plugging it into the charger.

CARE AND MAINTENANCE:



Extreme temperatures, vibration and shock should be avoided as

these may cause the damage to the unit



When cleaning the displays and casings, use a soft damp cloth

only. Do not wet the exposed metal part of the charging unit. Do

not use solvents or scouring agents as they may mark the LCD

and casing.



Do not spill water to the charging unit.



Do not make any repair attempt to the units. Take it back to its

original point of purchase for repair by a qualified engineer.

Opening and tampering with the units may invalidate its

guarantee.



Do not expose the unit to extreme and sudden temperature

changes. This may lead to the damage to the electronic parts of

the unit.

SPECIFICATIONS:

Input voltage for AC/DC adapter : 230V AC 50Hz

Charging current : around 250mA (for each battery)
