porcupine73 Posted August 29, 2010 Share Posted August 29, 2010 It all depends how much power you're drawing. If you have a large system and were really cranking it you could drain a starter battery in that amount of time. Especially if the battery is more than a couple years old. Starter batteries do not like to be discharged very much - doing that greatly decreases their life. Get a deep cycle battery if you want to run the stereo a lot without the engine running, such as an Odyssey or Optima or other AGM. Link to comment Share on other sites More sharing options...
edrach Posted August 29, 2010 Share Posted August 29, 2010 It's also possible that your alternator is not fully charging your battery any longer. Have the battery and alternator checked by someone you trust. Link to comment Share on other sites More sharing options...
Rooster2 Posted August 30, 2010 Share Posted August 30, 2010 Suggest pulling the caps off the battery to see if the water level is full in the battery. Link to comment Share on other sites More sharing options...

vasy Posted September 2, 2010 Share Posted September 2, 2010 I removed my 96 OBW left side door panel twice in the past 5 years to work on the window master switch. First time it didn't take me long but the second time, for some reason the panel did not want to go back. Took me a good 30 minutes just to reinstall the panel. Hope I don't have to do it again.
