You might want to read this >>> 2015 CRV Battery Drain And do a search for Parasitic battery draw on the forum.
Regarding your battery with a reading of 12.7 I would say it looks okay but you might want to get a high-rate discharge test done.
You might find this video of help >>>

Thank you hopefully I’ll look at all that, hopefully I’ll get it sorted!

I didn’t mean hopefully I’ll look at it, I meant I will!

340 ma is not normal for your CRV. That will deplete your battery by about 8 amp hours per day.... giving you only days on your battery if not driven often. It is an order of magnitude high. Should be closer to 30 ma

So you need to go sniffing for an abnormal parasitic somewhere.
I suggest this video as your starting approach to localize the issue and go from there:

Thank you, I must of had a 540 ma drain for quite some time which would explain it dying overnight if not driven that day, but in the cold it’ll die overnight regardless, obviously the problem won’t of gone away with 340 still there so I’ll watch the video and go through all the fuses

Thanks for posting that video. Saves me going to look for it 😉

 

Make sure none of the interior lights are staying on. Also have the battery tested. I've had a parasitic draw show up on a battery from an internal short.

 

Just thought I’d let people know, it was my mistake.. I held the multimeter on for longer, about 20 seconds and it went down to 0.00a. Checked it on the ma setting and said overload, then after 20 seconds went down to 14ma. Tried it with the Bluetooth plugged back and it was 0.54a then 0.34a, then 214ma no matter how long I held it on for. Unplugged it again and now it’s staying on 14ma. Hope that makes sense. Very happy 😀 I’ve had 4 years of batteries dying and thanks to this forum mentioning the Bluetooth module I’ve finally fixed it. The Rac must of checked it 4 or 5 times and never found it. Thank you for everyone’s help 😀

 

So it did turn out to be yet another nefarious bluetooth unit. Known to happen in your generation CRV... so all is right with the world I guess.. and it is not some other mystery drain that refuses to be uncovered.

 

RAC - LOL.

Utterly useless outfit.

 

The amount of times I’ve broken down though I’ve needed them 😂
