The battery on my 2004 GMC Envoy keeps going dead. With the ignition turned off it will go dead over night. I have tried to find the problem by removing fuses over night but still cannot find the problem. Can you give me any help or suggestions?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Paul, You can remove your battery and have it bench tested at your local auto parts store for the health status. You may have a failing stator in your alternator that could be pulling too many amps. You can pull both components and have them tested for free to insure your root issue is not your charging system.

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube Have the battery and charging system tested. Battery life is 3-5 years, if yours is that age you may need a new one.

Gelina Aquilina, Service Advisor / Mechanic at It could just be a bad battery if you're sure you haven't left anything on. Have the battery tested and go from there.

Helaine Kurot, Owner/Technician at 360 Automotive Start by having the battery and charging system tested. It could just be a bad cell in the battery. Pulling fuses, especially on a newer vehicle will cause more problems as it may cause vehicle computers to "not go to sleep". If you are handy with a voltmeter, measuring the voltage drop across the fuse will be a lot more accurate. Only a circuit that is still "awake" will have a reading (this will be in mV).
