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 a journey. CAUTIONS: 1. The charger is restricted to charging NiCd and NiMH rechargeable batteries only. Never use this charger for other types of batteries such as alkaline, lithium, carbon zinc or other types that are not specified. [. . . ] 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 16 mA" will be displayed. When the battery is overheated the charging will cease automatically. "000 Discharge Mode 17 displayed. 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 the user is recommended to carefully select the discharging current so that the charging current afterward will not be too high. 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 toggle between the "Charge", "Discharge", "Test" and "Refresh" mode. DISCHARGE MODE Current User-selected Discharging 100 mA current Thereafter Charging 200 mA current REFRESH MODE Old rechargeable batteries and those that have not been used for a long time require refreshing. This process will recover the optimum capacity of the rechargeable batteries. The afterward-discharging current will be half of the selected charging current (see Table 3). TEST MODE Current User-selected Charging 200 mA current Thereafter Discharging 100 mA current TRICKLE CHARGING 500 mA 250 mA 700 mA 350 mA 1000 mA 500 mA After the rechargeable battery is fully charged in any of the operating modes, the charger will give a small amount of current to the rechargeable batteries to maintain the fully charged level. This mode is automatically launched after rechargeable batteries are fully charged and kept in the charging unit. The signal "Full" will be displayed on the LCD. The maximum charging current is 1000 mA and is not affected by the number of rechargeable batteries inserted. 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. The 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 The user can use different display modes to monitor the rechargeable battery condition during the different operations (see below figure and Table 4 to 7). 22 23 Different display modes are exhibited: Charging current, Time, Voltage and Capacity Table 4.

(For example, 1:45 will be shown after the battery has been refreshed for 21 hr and 45 min. ) In case the power source is shortly interrupted or terminated when the charger is being operated, the operational mode will automatically be set to "Charge mode at 200 mA" to charge up the battery once the power source is back to normal, regardless the operating mode (Charge, Discharge, Refresh or Test) which has been selected by user before. 28 29 THE SIZE C AND SIZE D BATTERY ADAPTERS (FREE ACCESSORY) The battery adapters are used for connecting the AA battery to devices requiring Size C or D batteries. Install the AA battery into the Size C or Size D adapter as below. 2. [. . . ] Display--Use battery rating. . . re-chargeable never go whole way so for Voltage check for a 1. 5 you are looking at 1. 2 to 1. 4 For capacity on 2400 looking for about 1900 to 2100 (first time the capacity will be less like about 1700 to 1800). Why after I charge the battery to Full, remove, and test is not longer says Full? When you replace a charged battery it goes to trickle, and it can take from 1 to several hours to get back to a full charge depending on the condition of your battery. What is the charger capacity?If you must switch batteries in your product before they die what mode would you use to charge? --Refresh and charge. . . if you have several days --in a hurry just regular charge mode Maximum charging capacity is 3000 mAh My batteries are getting warm. It is common for batteries to get warm will charging. The charger has a built in temperature sensor which will stop the charging cycle if it has become too hot. Charging may resume 38 39 when the battery has cooled. [. . . ]
