Fast Charger For Nickel-Cadmium Racing Battery Packs (230-0226) Operation Faxback Doc. # 19921 Always use a battery pack until it can no longer provide the necessary power. CAUTIONS: This charger works only with 4.8-volt, 7.2-volt and 9.6-volt nickel-cadmium battery packs. Charging other types of battery packs could damage the battery packs. Be sure the battery pack is rated at 4.8 V/600 mAH, 7.2 V/1,000 mAH, or 9.6 V/600 mAH. Avoid charging fully-charged battery packs. Doing so can damage the battery pack or cause it to lose some of its storage capacity. Charge battery packs only at room temperature (65-80 degreesF). Charging battery packs in hot areas can permanently reduce the battery pack's power capacity. Charge only one battery pack at a time. Follow these steps to charge a battery pack. 1. Slide the battery connector of the battery pack you want to charge into the CHARGING JACK. WARNING: Connect or disconnect the battery plug only when the AC cord is disconnected. Otherwise, arcing and burning might result. NOTES: If the connector does not fit, turn it over and try again. Do not force it. If you want to charge a 4.8 volt nickel-cadimum battery pack, plug the small end of the supplied adapter cord fully into the battery pack's connector. Then plug the adapter cord's large end fully into the CHARGING JACK. 2. Insert the battery pack into the compartment in the battery charger. CAUTION: Be sure to insert the battery pack into upper side of the compartment first. Then secure the battery pack in place so it pushes down the applicable voltage selection sensors and two latches at the lower side of the compartment. 3. Plug the AC cord into a standard AC outlet. NOTES: After 7 seconds, the charger automatically selects the appropriate charging current. The CHARGE indicator lights when the battery pack is charging, automatically turns off when the battery pack finishes charging, and flashes when the battery pack fails to charge. If the CHARGE indicator flashes, check the battery connection. 4. When the CHARGE indicator turns off, unplug the charger's AC cord then disconnect the battery pack. NOTES: If the battery pack you want to charge is a new one or has not been used for more than 3 months, leave it in the charger for 24 hours, even if the CHARGE indicator turns off. Then unplug the charger's AC cord and disconnect the battery pack. When you disconnect the battery pack from the compartment, be sure to take out the lower part of the battery pack first.
