  • Page 11 Note: 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. When the transformer has been plugged to the power source, the version number of the charger (for example “29”...
  • Page 12 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.
  • Page 13 Charging current: 200 mA After 4 seconds from no more keys pressing, the LCD will blink once to indicate the setting is confirmed and Charge Mode the selected mode activated 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).
  • Page 14 “Full” sign is shown -The battery is fully charged Note : 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.
  • Page 15 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).

  • Page 16: Discharge Mode

    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.
  • Page 17 Discharging current: 250 mA Discharge Mode Note: The discharging current is always set to be half of the coming charging current whose upper limit is 1000 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.

  • Page 18: Refresh Mode

    Finally batteries will be fully charged in discharge mode and “Full” will be displayed. If user presses DISPLAY key at this time, "charge" icon instead of "discharge" icon will be displayed.
