devonia Posted January 26 Share Posted January 26 Hi, everyone, So up to January, everything has been fine. I've regularly left her parked up for weeks at a time. Now, the battery is going flat in a few days... So, I though - time to replace the battery. It's 80AH, or at least was. But when I took it up to the spare bedroom (no garage, alas) and recharged it - it didn't behave like a dead battery. It took agessssssssss to fully charge. Put it, fully charged, back and measured the output current (put a multimeter on the 10A dc range in series with the terminal - carefully NOT trying to start it). All parked up, doors locked, etc - just the bonnet open. After the initial surge - the current out seems to stabilise at about 0.47A. I couldn't spend long doing that as it is very cold and wet out there ... Clearly this is "something new" - even an 80AH couldn't handle that load for weeks. The battery's back in the bedroom - once it's charged I'll do a 20 hour discharge cycle and see how many AHr it gives.. Just in case. TLTR>>> Is there ANYTHING that I could have left switched on, that would stay powered up even with the key out? Drawing about 0.5A? I don't know - the backseat overhead player? Some setting of the media console? Otherwise, I will be pulling all the fuses out one by one, bridging the gap with the multimeter and seeing if any current flows.. But it is soooo cold out there.. And wet. And I can hear the wolves.... Quote Link to comment Share on other sites More sharing options...
