PhatB Posted March 2, 2010 Share Posted March 2, 2010 Don't think my battery is holding charge anymore, so wanted your advice to make sure. My supe was sat for almost 4 months from November til last weekend. Drove it about a bit on Sunday but last night when I went to take it out I had to jump start it Went for a drive about and probably did 70 miles and parked her up overnight. Tonight when I went to go out I thought I'd check the battery voltage first and noticed it was only 12.05v obviously not enough to start. Jump started it again, checked the voltage (14.25v) and put on all lights and blowers to see if it dropped which it never. Drove about for about 20 mins, parked up and checked to voltage when I switched the engine off (12.7v). Went back to the car an hour and a half later voltage was now 12.35v which I didn't think was enough to start it but it did. Will check it again in the morning. Any thoughts?

Geo Posted March 2, 2010 Share Posted March 2, 2010 Gubbed, replace it. Also could be the Alternator not charging it, but i reckon its the battery. Had the same issue with mine. Quote Link to comment Share on other sites More sharing options...
SUPRALOOPY Posted March 2, 2010 Share Posted March 2, 2010 Shove it on a trickle charge overnight. then take it to a battery specialist and they will drop test and hydro test it for you. Quote Link to comment Share on other sites More sharing options...
PhatB Posted March 2, 2010 Author Share Posted March 2, 2010 Gubbed, replace it. Also could be the Alternator not charging it, but i reckon its the battery. Had the same issue with mine. Kinda ruled out the alternator by the fact the voltage was going up to 14.25v with the engine running, so yeah thinking the battery. Shove it on a trickle charge overnight. then take it to a battery specialist and they will drop test and hydro test it for you. Just been talking to a guy I work with and that's what he suggested.

Stan Posted March 3, 2010 Share Posted March 3, 2010 I thought a battery should be about 11.8v when there is no load on it?? If you haven't had it long (i.e. a year or so) you might want to try a battery conditioner out on it first and top it up with some distilled if it's running low, something to do with crystals settling out of solution in it If not, off to hellfrauds!
