Folks,
Looks like my battery is on its last legs. Interesting search results when you try to find a replacement.
2.2 Diesel with start stop 2015 model
Anybody replaced theirs?
I know I need a EFB or similar but not a straight forward choice of battery.
Thanks in advance
Martin

I gave up in the end......
Web pages were suggesting incorrect batteries, non start stop, too small etc... even when I put in the correct license plate.
Given the very restrictive location, battery cover etc... I got one from my local Mazda dealer.....
Price wasn't too crazy either......

If you don’t mind me asking, what brand/version did you end up getting?

Exide EL954 from The Battery Group £115 a few months ago works a treat

Did either of you get your batteries coded to the car, so alternator knows you have a new battery, and sends out lower voltage for charging?
-
I didn't everything just worked.
Read about supposedly needing to code it in but never found guidance on how to do it.
I think if you can swap hem over within a few minutes most settings are retained.
Just for interest this cars battery did 5 years and my previous 2013 cx5 bought at 5 1/2 yesrs had a newish battery fitted.

You need a sophisticated diagnostic tool to re code battery; perhaps when car next in for service
you could get garage to do it. As I understand it, as battery ages +capacity reduces, the BCM will get the alternator to send out a higher charge voltage.
This isn't healthy for new battery.

Although this is true of recent BMW, Mercedes and VAG group models and some American makes I have found no reference to Mazda or other Japanese makes. But I stand to be corrected.
