pauleqer Posted September 24, 2007 Report Share Posted September 24, 2007 this battery is in my 2nd car with no system in i but i wanted to ask here cuz everyone seems pretty smart about these things. i bought it 2yrs ago, 94 saturn-36mpg FTW, brand new alt and fairly new looking batt. now if it sat for a few days the battery would die. so i got a new batt-ac delco, got it for free on a saturday discount . seemed fine for a while then started doing it again-when it was cold, usually if i left it for about 24hrs or so. its been doing it all summer and getting on my nerves, badly. bought a charger-$70 from walmart, good enough i figure. charged it, lasted 2.5 weeks fine no problems, even let it sit for 2 days and it was fine. now all of a sudden its doing it again and when i charge it the DD on the charger goes up to 16.9 then OL, im guessing over limit, but is still charging. i figure the alt is charging cuz when i jump it, drive it down the road for 3mins it starts fine, and the lights are always bright at night. sorry for the long post but...... what should i do? go get another new batt for like $70 and try that or a new alt for $140 and its a PITA to install?

mrrairai Posted September 25, 2007 Report Share Posted September 25, 2007 fairly new looking batt. now if it sat for a few days the battery would die. I don't think that has anything to do with the alt. I think you have a short somewhere that's killing your batts.

pauleqer Posted September 26, 2007 Author Report Share Posted September 26, 2007 (edited) I don't think that has anything to do with the alt. I think you have a short somewhere that's killing your batts. thats what i was thinking, but its just odd that it does this like erraticly. sometimes its fine for 2-3 days and other times is only a few hours. i removed the battery and put it on the charger, this is when its charging at 17V, which it didnt do before. it said fully charged, and i unhooked the charger and let it sit overnight. so now when i go to my moms today im gonna see if its dead or not. if its dead im just gonna get another batt and go from there, if not then idk. if it pisses me off too much ill just sell the dam thing haha, since i just got a new job(starting monday) ill be able to afford gas to drive the other car. going from 8.10/hr to 15.80/hr thanks Edited September 26, 2007 by pauleqer Quote Link to comment Share on other sites More sharing options...
