Universal Battery Pack Conditioner/Charger (230-0250) Features Faxback Doc. # 18518 Your Radio Shack Universal Battery Pack Conditioner/Charger uses advanced technology to condition and recharge 6- to 12-volt rechargeable battery packs. To prevent your rechargeable battery pack from losing its ability to fully recharge, you must completely discharge it (condition it) about once every 10 times you recharge it. Normal battery chargers can only recharge a battery pack.

Its features include: Multiple Charging Contacts - let you condition various types of rechargeable battery packs. Built-In Discharger - lets you condition your rechargeable battery pack for the longest life and best performance. Reversible Polarity Switch - lets you quickly reverse the charging polarity of an incorrectly positioned battery pack. Automatic Switching - automatically switches to the charging mode when discharging is complete. Automatic Voltage Sensor - automatically determines the maximum voltage a connected battery pack will be charged to. LED Charging Lights - show you the battery pack's charging condition. Temperature Sensor - protects battery packs from over-heating during charging. Battery Pack Versatility - lets you recharge Nickel-Cadmium, Nickel- Metal Hydride, and Lead-Acid rechargeable battery packs. Two Optional Power Sources - let you power the conditioner/charger using either standard AC power or your vehicle's battery power. (JC 12/28/95)
