Richie 32 Posted September 10, 2008 Hi. I have tried 2 fully charged batteries in my 205 gti. They manage to start the car great, and things are fine. However, i turn the car off, and leave it for 15 minutes and when i return, it just won't start. I check the batteries, and apparently the car has made them "unservicable". So, basically, they are screwed. They were fine batteries too before they went it, and as both batteries have started the car initially, i need to find out why my car thinks its ok to eat my batteries. Is something majorly draining them to a point where they break? or is something in my electrics thats breaking them? I have a new battery sitting in the garage, but im a bit reluctant to feed it to the pug until i know whats causing the battery breakage Any ideas folks? Cheers Rich Share this post Link to post Share on other sites
Anthony 1,003 Posted September 10, 2008 If they're dying in 15 minutes, there must be a big power drain somewhere - should be easy enough to trace with a multimeter I'd say Share this post Link to post Share on other sites

Richie-Van-GTi 71 2 Cars Posted September 10, 2008 To discharge and leave unserviceable that quick would be a direct live to earth i reckon. Start by checking wires from the live terminal to the fusebox and the shunt box etc. Main live to get damaged and short his way though would be from battery to starter and alternator, check its not rubbed through with engine movement Share this post Link to post Share on other sites
Richie 32 Posted September 13, 2008 I've been messing about with this for ages and i still can't fix the problem. Its possibly something glaringly obvious but i just can't do it. Anyone recommend me a mobile auto electrician in the mids area? (car isnt taxed/insured so i need a mobile car sparky to come out) Share this post Link to post Share on other sites
Guest Modman08 Posted September 13, 2008 Hi mate, Im having a similar problem, in that my car recently cooked a supposedly good battery. I made a post about a terrible egg smell in the car, which Pugnut pointed out that it was most likely burning sulphur from a dying battey. It indeed was, as the battery was getting boiling hot and spewing out acid everywhere, before finally just giving up and leaving me stranded on the side of the road. I swapped the battery, but even the new one is leaking and getting too hot. I checked the voltages and apparently my alternator is naffed because its kicking back around 18volts! I was just wondering have you tried testing yours? Ive been recommended to change my alternator asap to avoid killing this new battery.

Richie 32 Posted September 14, 2008 Ah right, thanks for that i'll check. Might sound like a dumb question, but should the battery get warm when your cars in use or remain cold? I think my battery may be getting warm/hot too. Theres no smell though. Plus i havn't actually driven the car anywhere, its only been idling for ten minutes before switching it off and then restarting it, which it then doesn't work. It seems to have a mind of its own at the minute. I was under the impression it had killed another battery yesterday. I'd fitted a brand new one, and it fired up fine. 15 minutes later it wouldn't work (as before). I took the battery leads off, waited for an hour or so, randomly tried it again and it started straight away several times. :\ Share this post Link to post Share on other sites
