Diagnosing a Dead Battery
courtesy of Bob, The Auto Answer Man
My daughter has a problem with her 1999 Blazer. She has a new $80 battery that is not holding a charge. She has had the voltage regulator tested and battery tested but not load tested. Voltage checks out okay. She has been disconnecting the battery at night to see if it discharges overnight. It is dead by morning when connected. When disconnected, it is very low. Is it something electrical or a bad battery?
If she is disconnecting the battery every night, and in the morning, the battery is very low, then it must be the battery is bad. If there was a short in the car, it would not make a difference since the battery has been disconnected.
