[. . . ] The charging current can be set up to 1500 or 1800 mAh when two batteries are charged. Fast charging ­ 70 mins to charge up 2000 mAh batteries Individual LCD display for compartments Charging both "AA" and "AAA" rechargeable batteries simultaneously Overheat detection to protect rechargeable batteries from over-charging Minus delta voltage (-dV) detection for charge termination Damaged batteries detection Discharge mode (first discharging and then charging) to remove memory effect of rechargeable batteries Refreshing old rechargeable batteries by discharging/ charging cycles Test function to check the capacities of rechargeable batteries Charging/ Discharging functions can be launched independently and simultaneously to each rechargeable battery in the compartments 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) There are three easy-to-use function keys and four number keys in the charging unit: Compartment Number keys CURRENT key DISPLAY key Press and release the Number key to select a particular battery compartment for charge modes and/or display mode adjustment. 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. [. . . ] After 8 seconds from no more keys pressing, the LCD will blink once to indicate the setting is confirmed and 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). After the rechargeable battery is fully charged, "Full" sign will be shown on the display and the user may take out them at this time. or if the rechargeable batteries are kept placing at the compartments , trickle charging will start. The trickle charging current is around 5% of the selected charging current to keep the rechargeable batteries being full. 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. If one wants to change the applied current afterward, the rechargeable batteries must be taken out and inserted again. The maximum charging current of other rechargeable batteries are restricted by the current setting of the first inserted rechargeable battery. For instance, if the first inserted rechargeable battery is set to charge at 700 mA, then the second, third and fourth rechargeable batteries can be only set to charging at a maximum current of 700 mA. Therefore, user is recommended 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, user can press the MODE key (for selecting all rechargeable batteries) or NUMBER key then MODE key (for selecting individual rechargeable battery). 8 seconds after the last key press the LCD will blink one time to indicate the end of changing. When overheating condition occurs (over about 53°C, usually due to too high a charging current selected), the charging will be stopped immediately and the display will shown "000 mA", the charging process will only resume once the temperature of the rechargeable batteries drops to a safe level. If overheat conditions continue to occur, the rechargeable batteries shall be taken out to cool down and then charged at a lower current. For new rechargeable battery it is recommended to charge it with 200 mA current for reconditioning it from the long storage status. Discharge mode will first discharge the rechargeable battery then charge it. 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. The subsequent pressing of the mode key will enable to toggle between the "Charge", "Discharge", "Test" and "Refresh" mode. ) Then user may also select different discharging current (see Table 2) by pressing the CURRENT key, within 8 seconds after inserting the batteries. (The display will blink once to indicate the setting has been confirmed and the current cannot be changed afterward.
