Alternator Denso or Duralast
Nippondenso (Denso) is what I would choose, I believe this is the OEM manufacturer.
I would get Denso
Replaced the 2017 ACDelco alt with a Duralast Gold 160 Amp. Life time warranty. For 200 bucks at Auto zone. Hope this is the last one I buy.
Had the same issue with a reman denso alternator that went in a Honda, it was the cheap diode/rectifier pack that was fitted that was causing the bat light to stay on.
you can go on rockauto.com and should be able to purchase an OEM Denso Alternator.
If you are going to get a new or remanufactured alternator spend the $$$ for a DENSO one.
As some others have said, make sure you only get the remanufactured Denso alternator. No other alternator seems to work.
Right on schedule, about 7 months later, that reman also went out and I decided to pay more to get the Duralast Gold which is all new. That one lasted about a year and a half but then the bearings went out on it, but I don't think that issue was the alternator's fault because after I replaced it, I found out the Harmonic Balancer had lost its integrity and was wobbling a little. Again, not sure what caused what (did the bearings put extra pressure on the aging balancer or did the balancer go out and damage the alternator?), but all I can say is that since replacing the harmonic balancer and using the Duralast Gold alternator, I have not had any issues for over 2 years now.
When I lived in walking distance of a 24-hour AutoZone, there seemed to be more people waiting in line to get their lifetime-warranted DuraLast alternators replaced than for battery replacements.
I replaced my original alternator (which is also denso out of the factory) with a brand new denso alternator. Should be the exact same thing as the factory alt. It's not working at all. Battery is not staying charged. Had a complete diagnostic done by Honda and they said it is the alt. Kinda disappointed I waisted $700.
