Wondered if you can help?  I value your Subaru expertise

I had a new battery fitted in 5^th November 2020, and had been using the car quite often.

When the last lock down kicked in I didn’t use the car much at all.

I experienced a flat battery on 22^nd Jan so put on a fast charge and had the battery checked where I bought it. They said it was ok but need a full charge.

Out came the battery charger again and trickle charged it over a 24 hour period, it was reading 12.6 volts on my multi meter.

Since then I have experienced battery drain over a 2 -3 day period.   I have made sure all interior lights are off.  

A TV receiver that was under the driver’s seat, (left in when it was imported), was removed.

I checked if anything else was left on but couldn’t find anything

On 24^th Jan the battery was 11.9 volts , I had to go out in the car and after 9 miles it read 12.3 v. next morning it 11.82v

Next day 11.46v

Next day 11.27v

Next day 10.76v (the 28^th) I charged the battery 12.5v

Next day I  did 6 miles and it read 12.5 v

Next day 11.67v  we did 8 miles that day and it read 12.1v when I parked up.   

Over the next week I did 10 miles one day and 20 miles the second day.

When not using the car the battery was losing around 0.5 to .08 v each day.  

Last Tuesday the battery was charged and at 12.16v, I pulled the radio/clock fuse, (the radio/sat nav/phone etc. was fitted by the importer) and checked it the next day it read 11.4v , so not that.

Thursday it was 10.3v and wouldn’t start, it was very cold too. -4 degrees!

I fast charged the battery , 12.7 v and went shopping after I got back it was 12.8v. I put the radio fuse back in and pulled the heated seat fuses (retro fitted)

Did a short run last night, to the chip shop! and when I parked up it was 12.3v.

This morning it was 11.65v. so not the heated seats!

As you will no doubt gather there is a drain on the battery somewhere,.  Do you have any ideas?

The alternator charges at 14.6V so that seems ok.

Sorry for the long drawn out e-mail , just hope you can throw some light in it?? (no pun intended)
