Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Planet-9: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Drove my '10 CS yesterday about 10 miles, went to drive it today and it's dead. Key wouldn't come out, couldn't open the frunk - but I know how to overcome those problems. Is there a mian fuse? Battery shouldn't be dead, and I put it on a slow charge for 8 hours, no lights or partial crank, and the key stuck in again. Like there's no battery, buy just drove it yesterday.:crazy: Thanks for any help.

POST 2Original post

Maybe a dead cell. Have you tried measuring the battery voltage? I think there are some large fuses somewhere on the passenger side but don't know more that that.

POST 3Original post

how old is the battery? if you haven't changed it yet, its a good idea to do so....

POST 4Original post

Back in the day, we always got some indication of a battery going south. Things like slow cranking, dim lights, etc. were always a part of the failure. Not any more. The last few batteries that failed on me just gave it up without warning. Good one day, bad the next . I suspect your's is behaving the same way. The first thing I'd do is to get it out and take it somewhere to be tested. I'm pretty sure you'll be returning with a new one.:cheers:

POST 5Original post

I replaced the battery 3 years ago, when the car was 3 years old. When I drove it the day before it the starter cranked fast and there was no indication of a weak battery. I've never had a battery die out completely over night, but maybe that's the case.

POST 6Original post

Don't know if the newer AGM or gel batteries have the problem but a dead cell in the older wet cell jobs could kill a battery in short order. Debris from the plates flakes off, builds up and shorts the cell. IIRC wouldn't hold a charge long enough to start the car just after shutting it down. No warning. Got the tee shirt... Three years is a little quick but it happens.

POST 7Original post

My last battery failed at around 3 years - I know this because it was about 6 weeks out of warranty!! It also failed without warning.

POST 8Original post

It would seem unlikely that the battery would be dead unless it is defective. Does it have a warranty?

POST 9Original post

Sometimes, cars that don't get driven a lot develop a "film" on the battery posts (electrolysis?). Take the battery leads off, give the posts and the inside of the clamps a good cleaning with a battery post cleaner, and sometimes you don't even have to charge the battery. Had this happen just last week with my Cayman S . Cleaned the posts, fired right up. I still went ahead afterwards, disconnected the battery, and gave it a good charge. I then proceeded to to it on all my personal vehicles since none get driven much. I have a company car.

POST 10Original post

Sounds like a dead cell. Try a load test. If it drops below 9.2 volts it's toast.
