Left my car garaged for 3 days without using it last week. When I came to start it the battery was flat (some electrical lights on the dash etc came on but not enough power to start up, after a while the dash lights started flickering as well).

I hadn't left any lights or anything on and the front part of the head unit had been detached so unlikely to have been caused by something left on.

So jump started went for a drive and was fine for a couple of days.

Had the car in the garage again over the weekend, hadn't used it for 36hours- came to start it again today, same problem. So jump started and went for a drive again.

When I got back - followed the battery faq to check with a multi meter.

Checking the charge in the battery read 12.40 volts which means it charged back up fine once I had been out in it.

So then checked if anything was draining it while the car was off- by disconnecting the negative terminal and putting the meter between that and the negative post in amps mode. Read 0.00 no matter what setting I put it on. I would have thought there would have been a small reading for the clock / odometer / ecu etc but nothing at all?

Any ideas? Is my battery just knackered? How do I tell if it is? Would it be charging up to the correct voltage if it was?

Ahh, I might go and check that now. Was just following the faq:



Haven't checked alternator output yet may do it in the morning but I presume it's fine as it charged the battery up to the correct voltage again after it was dead.
