  • Page 5: Preparing To Charge

    Model 12248 BatteryMINDer ® NEVER CHARGE A FROZEN BATTERY OR ONE AT A TEMPERATURE ABOVE 123° F. PREPARING TO CHARGE If necessary to remove battery from equipment to charge. Always remove ground terminal first. Turn off all accessories in the vehicle, so as not to cause an arc. Be sure area around battery is well ventilated while bat- tery is being charged.

  • Page 6: Dc Connection Precautions

    Model 12248 BatteryMINDer ® DC CONNECTION PRECAUTIONS Connect and disconnect DC output clips from battery only after removing charger power cord from outlet. Attach clips to battery posts and twist or rock back and forth several times to make good contact. This tends to keep clips from slipping off terminals and reduces risk of sparking.
