1997 Chevy Silverado V8 Two Wheel Drive Automatic 177000 miles
I have a Sivlerado with an after-market, competition level stereo system. I have a high-output amplifier, powering 3 Amps, 3 capacitors, 4 subwoofers, and 8 midrange and tweeters. When my car is powered on, the capacitors read 13.6 - 13.9 Amps, and my voltage gauge reads around 14.
My battery seems to be failing. I had left my lights on all day, which killed my battery. I had it jumped and when I got home I put it on a charger, and did not have a problem again. A few weeks after that, my wife left the dome lights on overnight which again killed my battery. Again I charged it overnight and it was fine for another few weeks.
Now, for no apparent reason, my car wont even hold a charge for more than a few hours. It seems to be deteriorating more rapidly. If I charge it overnight, it will fire up OK for a while, but when I went to work, it did not even last a 7 hour day.
Sorry for the long description but I wanted to provide as much info as possible before asking my questions.
My question is: has the multiple charges and discharges caused my battery to go beyond the ability to hold a charge? Or does that seem circumstantial and it could be something else.
Right now I have a cheaper Carquest battery, but am replacing it with a higher end Optima battery. I just don't want to get my hopes up if this is not the issue.
Any advice/help would really set my mind at ease.
have the same problem?
