Put mine on a slow trickle for 3 days and all appears to be well at the moment.

I had a lot of problems with flat batteries as the car is not used much. I installed a ctek battery monitor which bluetooths to a phone and lets you know when it is getting low and needs a charge. Much better than my old method of waiting till it wouldn't start!!

I was getting this last year, eventually killing a battery altogether.  Multimeter showed one drain was coming from a bad interior LED light, then one night walked past car to hear aux pusher fan running slowly (car hadn't been used for a few days). I now pull the large red fuse 75 if I park the car up for more than a few days (e.g. airport car park etcs)
