INTRODUCTION: Congratulations on purchasing this intelligent charging unit which enables definitely 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.
CAUTIONS: 1. 2. 3. 4. 5. 6. 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. The charging unit shall only be used only at normal indoor room conditions. Always follow the charging instructions for the rechargeable battery. Observe the recommended charging current of the rechargeable batteries.

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.
b. c. d. Discharge then charge up the rechargeable battery (DISCHARGE) – to discharge the rechargeable battery then charge it for minimizing the memory effect. 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.
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 700 ~3 hr 35 min AA 2500 mAh 500 ~5 hr 200 ~13 hr 700 ~60 min AAA 700 mAh 500 ~84 min 200 ~3 hr 30 min Note: z z User shall always observe the recommended maximum charging current of the rechargeable batteries.
z mode to the new rechargeable batteries in order to achieve the optimum battery capacity. 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.
START CHARGING THE RECHARGEABLE BATTERIES Once a rechargeable battery is inserted after the transformer has been plugged to the power source, the battery voltage (for example, “1.39V”) will be displayed for 4 seconds. Then “200 mA Charge” (default mode) will be shown on LCD for another 4 seconds, indicating that charging with 200 mA is to be started if no alternation in setting is made. Within this 8-second time from inserting the batteries the user may first select the operating mode by the MODE key.
Charging current: 200 mA After 8 seconds from no more keys pressing, the LCD will blink once to indicate the setting is confirmed and the selected mode activated Charge Mode During charging, the different displays- Charging current (in mA), Time elapsed (in hh:mm), Terminal voltage (in V) and Accumulated capacities (in mAh or Ah) may be toggled and selected by pressing the DISPLAY key (refer Table 4).
“Full” sign is shown -The battery is fully charged Note : z z The current cannot be altered once the setting has been confirmed in the initial stage. This can avoid the user changing the current setting accidentally while doing setting on other rechargeable batteries. If one wants to change the applied current afterward, the rechargeable batteries must be taken out and inserted again.
z z Therefore, user is recommend to place the battery with the highest expected charging current at Compartment 1 first. To release the restriction of setting charging current, user shall take out all four rechargeable batteries from the charging unit. To change the operating mode during charging, one can press the MODE key (for selecting all rechargeable batteries) or NUMBER key then MODE key (for selecting individual rechargeable battery).
z For new rechargeable battery it is recommended to charge it with 200 mA current for re-conditioning it from the long storage status. DISCHARGE MODE Discharge mode will first discharge the rechargeable battery then charge it. It is for removing the memory effects of rechargeable batteries. By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the Discharge mode can be selected. (The mode key shall first be pressed and held for about 1 second to activate the mode change.
Note: The discharging current is always set to be half of the coming charging current whose upper limit is 700 mA (see Table 2). Therefore user is recommended to carefully select the discharging current so that the charging current afterward will not be too high. Table 2. DISCHARGE MODE Current User-selected Discharging 100 mA current Thereafter Charging 200 mA current 250 mA 350 mA 500 mA 700 mA Finally batteries will be fully charged in discharge mode and “Full” will be displayed.
Refresh mode will start with discharging the rechargeable battery, then charging it. The repeated discharging and charging cycles will be launched until no further increase in the measured capacities is estimated. Discharging current: 250 mA Refresh mode (the battery is being discharged) Note: z By pressing the MODE key within 8 seconds after inserting the rechargeable batteries, the Refresh mode can be selected.
z z Then user may also select different discharging current by pressing the CURRENT key (see “Note” in Discharge mode and Table 2), within 8 seconds after inserting the batteries. (Or the display will blink once to indicate the end of setting and the current cannot be changed afterward.) It may take up to several days to finish the refreshing process, depending on the selected discharging current. The maximum refresh current is 350 mA.
The Charging current in (mA) Test mode Note: z After selecting the Test mode, user may select different charging current in the Test mode by pressing the CURRENT key, within 8 seconds after the batteries are inserted. The afterward-discharging current will be half of the selected charging current (see Table 3). Table 3.
z z The maximum charging current is 700 mA. After the test mode is finished, the display will shift between the “Full” sign and the battery capacity (in mAh or Ah) automatically in 3-second intervals until the rechargeable batteries are removed. User can switch to other displays by pressing the DISPLAY key. Battery capacity displayed in (mAh) as the checking is finished in Test mode.
DISPLAY MODE INFORMATION User can use different display modes to monitor the rechargeable battery condition during the different operations (see below figure and Table 4 to 7).
