I-eloop battery replacement

A while back I had made a post regarding a battery management system warning message on my 2015 sGT with around 38k miles. I would appear that may be an issue with my battery and after doing some digging it looks like there are specific batteries Mazda provide for vehicles with the I-eloop system.

I wanted to see if anyone can confirm this is the case and if so, what kind of costs I may be looking at for a replacement battery.
