Flat battery in less than 2 weeks

[Andy H]

Hi all,

I've previously left my car for 3+ weeks and it's started no problem. The weekend before last I drove over 200 miles so the battery should have been fully charged on my return. This morning the battery was completely dead and I had to use the manual key and then boot access. I connected my rapid boost charger and after a while I was able to lock and unlock the doors again. I'm going to keep it on charge for a few hours but it's introduced that element of doubt and worry for my weekend trip.

I'm sure I didn't leave anything on in the cabin and there are no after market accessories connected (no tracker). I don't suppose there's any way to know what caused this after the event. Has anyone else found themselves in a similar position and managed to do any analysis with a multimeter to at least prove there's a parasitic drain?

Thanks, Andy.

I use a CTEK CS Free, battery extender. Its a lithium ion battery that connects to the car battery (essentially a second battery) It extends the life the Emira battery about 2-3 weeks when parked and not used. It can also be charged by the car when you are driving. Its about $225. Size is about 3X3X10 inches.
