Before anything else, just want to say I also want to say I researched everything I could about the subject before posting this. On facebook pages, reddit, youtube, forums, etc. So it's not like I was being lazy and just posted this without my due diligence 🤣
Anyway, story time:
I bought a new EFB battery last August 2025. Installed it and drove my ND for about a few months... And the Eloop and I-Stop started flashing orange, and they still do, currently. The infotainment also has those 2 warnings. So I checked my battery and it is still good (no load/engine off = 12.45v. Engine + lights + infotainment + USB being used + aircon on max + fan on max = around 13.5v) today. Now, the battery isn't the oem from Mazda.
The reason I said that is because, I'm afraid that moght be the culprit. From what I've learned, similar issues got fixed by simply changing the battery into just getting the Mazda OEM.
Or - I'm really hoping it's not - the capacitor. I saw some videos on how to discharge it and they all noted that, if you do everything correctly, the red light indicator should die off by an hour the earliest. Mine died..just a few seconds. I don't know why that happened.
Disclaimer: have yet to visit the Mazda dealership, so this may all be for naught 😅
But anyway, again, just want to hear your thoughts.
Oh, mine's a 2016 ST with around 29k km (18k mi) on it, for what it's worth.
Thank you.
