Battery Life?
My Acura is getting close to its 4th birthday, with 26.5K miles on her. The last time it was in for service in August, they said the "battery is fine". Never had a battery last 4 years in ages. Typically with modern vehicles, you don't get a warning once the battery goes - thats been my experience in the past.
When did you all replace your (if you have done it)? Costco has a battery that fits the RDX for about $168, not sure how much one would be at the Acura dealer.

Had my 2019 for almost 6 years now - purchased 11-20-2018. 18.3K miles - I have an electric MINI Cooper for daily use.
Dealer tested battery during routine service earlier this month - Rated at 650 CCA, tested at 590 CCA. Should be fine for another winter.
I do connect a CTEK charger when I'm not going to use the RDX in the near future. Permanently attached the charger connector to the battery and brought it out near the driver's windshield wiper pivot so I don't need to open the hood to connect the charger.

I took delivery of my '19 on 11-01-2018 and replaced the battery this year. Not because it was dead or even seemed like it was dying, I just figured it's been 5 years, I have a big road trip in somewhat cold weather coming up, so I just replaced it. I did not experience any issues others did when disconnecting power, etc with the warning lights, lack of starter, etc.

My auto start/stop has been working far less than it should be lately - I suspect my battery is getting weak. Basically it always says the system is warming up/charging, even if I just completed a 150 mile drive, and there are no other symptoms I'm aware of that point to the battery. Never an issue starting the car normally though. Mine is a 2022 with 24k miles, but I do live in the Phoenix area and for me 2 years is normal for a battery.

Acura/Honda batteries are terrible and I have had many just randomly die on me with little warning prior so if you are thinking about replacing it just do it, as four years is good enough on it and no harm in doing so.

Costco warranty now seems to be pro-rated from day one, and is only 3 years. So, if it dies in a year you get a credit for 2/3 of what you paid to apply to the purchase of another battery.
Walmart has a similar battery for $10 more, with a 4 year free replacement warranty. https://www.walmart.com/ip/EverStart...-CCA/944775111

Battery replacement is free if it dies within the factory 4yr/50k warranty.
I usually see Honda/Acura batteries die in about 4-5 years. First sign is the srs light going on, but that was back on my many 2008 and earlier models. Newer models tend to be a random emmissions or safety system error according to forum posts, but I went from a 2008 to a 2020+ and the newer models haven't failed on me personally yet.
Normally I don't bother with an early replacement. The lights pop up well before you get stranded, but are sporadic so if you see it once you know your battery is due. Only when I've gone weeks too busy to react to the light, have I gotten stranded. But I have AAA and Acuracare free roadside assistance in case.

I had to replace the battery on my 2020 model in 2023 at about 31K miles. It failed almost exactly 4 years from the car’s build date.
The only symptom was the auto start/stop not working well. When tested it failed the amperage spec though I don’t recall now how badly.
For what it’s worth it failed at the end of a hot summer in southern Arizona, and I would characterize it as fairly sudden.
I went with an Interstate battery from Costco.
