User manual LA CROSSE TECHNOLOGY BC-900

[. . . ] FEATURES: The Charging unit Charging rechargeable battery in various current (200, 500, 700 or 1000 mA). 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 all 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) INVENTORY OF CONTENTS 1. Size "C" battery adapter (4) & Size "D" battery adapter (4) 4. [. . . ] The subsequent pressing of the mode key will toggle between the "Charge", "Discharge", "Test" and "Refresh" mode. · There is a 4-second time allowed for choosing further functions after each key pressing. If no more keys are pressed, the LCD will blink one time to indicate the end of setting. Afterward, the current can no longer be changed during the process and the selected mode will begin. · Charging current: 200 mA After 4 seconds from the last key press, the LCD will blink once to indicate the setting is confirmed and the selected mode is 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). After the rechargeable battery is fully charged, "Full" will be shown on the display and the user may take out them at this time. If the rechargeable batteries are left in place in the compartments, trickle charging will start. The trickle charging current is around 5% of the selected charging current to keep the rechargeable batteries full. "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 prevents the user from 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 the 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, the user is advised to place the battery with the highest expected charging current in Compartment 1 first. To release the restriction of setting charging current, user must 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). Four (4) seconds after the last key press the LCD will blink one time to indicate the end of changing. When overheating conditions occur (over about 127°F (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 must be taken out to cool down and then charged at a lower current. When the battery is overheated the charging will ceases automatically. "000 mA" will be displayed. For a new rechargeable battery it is recommended to charge it with 200 mA current to re-condition it from the long storage status. DISCHARGE MODE 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. Then the 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. ) Discharging current: 250 mA Discharge Mode 3 Note: · The discharging current is always set to be half of the coming charging current whose upper limit is 1000 mA (see Table 2).
