User manual LA CROSSE TECHNOLOGY BC-500

[. . . ] Ability to charge both "AA" and "AAA" rechargeable batteries 4 simultaneously. Discharge mode (first discharging and then charging) to remove memory effect of rechargeable batteries. The charging/discharge/test function can be launched independently and simultaneously for each rechargeable battery in the compartments. The LCD of the charger displays the operating status of the different modes. [. . . ] It is the responsibility of the user to make sure that the batteries are either NiCd or NiMH type and not alkaline or carbon batteries. 10 Carbon or Alkaline batteries may cause the charger to display the "DEFECT". These types of batteries are NOT suitable for this charger. DEFECT INDICATOR The "DEFECT" indicator will flash (Figure 6) for a while on the LCD while the charger detects the battery condition. If a defective battery condition is detected, the "DEFECT" sign will remain on until the defective battery(s) are removed. Warning: This charger will not necessarily recognize all types of defective batteries. Owner discretion is required before attempting to charge batteries of any condition. If "DEFECT" is displayed, a bad battery has been placed into the charging unit. (Figure 6) 11 DISCHARGE MODE To select the Discharge Mode, press the MODE key for 3 seconds after the status of the batteries is displayed. When discharging, the "DISCHARGE" sign and battery voltage (Figure 7) will be shown on the LCD. Discharging voltage (Figure 7) Discharge Mode After fully discharging the battery(s), they will be re-charged again. Once the battery is full, the voltage will be displayed with the "FULL" sign. The charger will switch to trickle charge with around 5% of the charging current to keep the rechargeable batteries full. TEST MODE Press the MODE key for 5 seconds after the status of the batteries is displayed, and the Test mode can be selected. In Test mode the 12 rechargeable batteries will first be fully charged and then discharged to determine the battery(s) capacity(s). During the first charging cycle, the display of current (Figure 8) and voltage (Figure 9) will alternate on the LCD. The charging current (Figure 8) Test mode The charging voltage (Figure 9) Test mode 13 When in the discharging stage, the voltage (Figure 10) and discharging capacity (Figure 11) are displayed alternately. The voltage (Figure 10) Test mode The discharging capacity (Figure 11) Test mode During the second charging cycle, the voltage and the total capacity are displayed alternately. 14 When the rechargeable batteries are fully charged, the capacity (Ah) (Figure 12) and the voltage (V) (Figure 13) will be shown alternately with "FULLTEST" displayed on the LCD. The capacity (Figure 12) Test mode The voltage (Figure 13) Test mode Note: When any one of the batteries is in the test mode, do not change the other battery(s). To test additional battery(s), you must remove and reinstall the testing batteries and then reset the mode. 15 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 the rechargeable batteries are fully charged and kept in the charging unit. The "FULL" or "FULLTEST" sign will be displayed on the LCD according to the mode user selected. CARE AND MAINTENANCE: Extreme temperatures, vibration and shock should be avoided as these may cause the damage to the unit. Do not use solvents or scouring agents as they may mark the LCD and casing. Take it back to its original point of purchase for repair by a qualified engineer. Do not leave unattended while powered, especially in a vehicle. 16 SPECIFICATIONS: Input voltage for AC/DC adapter: 110V AC ~ 240V AC Input voltage for DC car adaptor: 12V DC Input voltage for Charger Unit: 12V DC (use supplied adaptors only) Charging current: Approximately 500mA (each battery) Max charging capacity (capacity of rechargeable batteries): 3000mAh Dimensions (L x H x W) - Charging unit: 2. 60" x 4. 87" x 0. 88" (66 x 123. 8 x 22. 3 mm) LIABILITY DISCLAIMER: The manufacturer and supplier will not accept any responsibility on the improper or incorrect use that makes any consequence occur.
