OEM Battery Life

Needed to jump start three times on 3 rd year anniversary. Dealer replaced battery under warranty. Two years later battery tested bad and dealer wants full price to replace. In 48 years of car ownership, I’m use to 4-5 year battery life, certainly never 2!!! No satisfaction from corporate complaint. IMO, Acura is using low quality Batteries which is unacceptable from a “Premium” brand and their customer service could care less. No wonder their reliability ratings have plummeted. It can’t be considered a “luxury car” if you have to worry if it’s going to start. They’ve lost this long time customer.

My battery died at just past the 3 year point. It was a small (IMO underpowered) battery that probably should never have been put in the RDX. I knew it was under warranty, but didn't want another underpowered battery in it so I went to Walmart and bought one with 775 CCA. I don't remember the CCA of the OEM battery, but think it was 500 something.

Tons and tons of variables regarding battery life. I, personally, have had very good luck. I recently replaced the battery in my 08 TL-S which was previously replaced under warranty at 3 years. I bought the car as a CPO and had owned it a year. Went to the garage and it was completely DEAD - couldn't even unlock the door. No previous signs or warnings. Replaced under warranty and lasted just over 8 years. Just replaced with an Interstate Megatron Plus and like snorf, I went with a bigger badder CCA one. I think the OEM one was 550 and this one, I believe is 700 or 750. We have a 16 RDX Advance and it still has original battery (in service date is 2/15/16). Bought an 04 TL and it still had the original battery when I traded it at just over 6 years.
Many will agree that Honda / Acura are using crappy batteries but I may be the exception. Garage kept and what I would consider intermediate commute distances.

Who knows why the battery failed?

Did the dealer also test the charging system before replacing the battery under warranty?

Did the owner let the battery drain by leaving the lights on? Or was the vehicle stored for several months?

My last two batteries lasted over 15 years each. They last if looked after.

I don't remember the CCA of the battery in my '16 Advance, but IIRC it was 550, but I could be wrong. I do recall thinking that it was about the size of a battery I would expect to see in a subcompact car and not an SUV. Our RDX is garage kept and we've never left the lights on. We don't play the radio when the car isn't running. I'm 61 years old and have been driving since I was 16 and this is only the second car I've owned that I've had to replace the battery. The first was a 2000 accord where the battery lasted about 4 years. We've kept all our cars from 5 to 15 years.

It might have been; depends on the market. Where it is colder, they may up the CCA and Ah.

One thing that is missing in many cars is a voltmeter. They are so handy for letting the driver know what is going on charge-wise. I have one on my motorcycle and my car that I made. My other car has one that I can select in the menu.

OEM Battery Life

i’ve owned cars for 47 years and never had a battery die after 2 years (2 new Acura batteries failed over 4 years!). The dealer verified the charging system is fine and I did not leave a light on or abuse the batteries in any way. IMO Acura’s OEM batteries are very low quality and they refuse to admit it and remedy the situation. Surveys prove Acura’s declining quality and battery problems are one of the reasons why.

I have not seen surveys supporting this claim. The Consumer Reports survey is the most comprehensive that I am aware of, and it has the RDX reliability above average for the last few years, with "Electrical System" much better than average. Can you provide a survey that supports declining reliability of the electrical system?
My battery died after 3.5 years. That's a little earlier than I would have expected, but not completely unacceptable. I would be frustrated with a battery that only lasted two years, but I would also expect most batteries to be under a pro-rated warranty for at least that long.

Well I would find that totally unacceptable. I can't comment on the cars that I have had for a few years (VW bought my VW Diesel back after 4 years) and my RDX is coming up on 2 years, but the last two cars (15 and 16 years) still had the original batteries in them and they would start in the coldest of winters.

Well you cannot fault the battery in that case since you bought the car "used". Who knows how the previous owner maintained it.

I bought a car that was 3 years and 1 month old. It had 101 miles on it and 6.77 hours on the engine. So it sat around a lot and who knows if the previous owner had it on a battery maintainer. So if it fails, I can hardly blame the battery. Batteries last if I look after them.

I just changed out my original battery on my 2015 RDX that was purchased in mid 2014. I noticed that it was cranking a bit slower. I use a Battery Tender to keep it topped off. But within a day, it starts to crank slower then usual. So I got about 4.5 yrs out of this one. I didn't want to wait till it failed. Cranks great now with an Interstate battery for about a month now without the Battery Tender.

The OEM battery in my 2016 died after 40 months of ownership. Since most of this time was in Phoenix I consider this to be very good and above average since anything over about 3 years and you are on borrowed time. Dealer replaced it under warranty at no charge. OEM battery was 610 CCA, replacement is 630 CCA. If this new battery only lasts 2 years I guess I could start bitching and whining or be thankful Acura covers the battery under their bumper-to-bumper warranty and I got over 5 years between the two. Most OEM's don't cover the battery under their warranty from my experience.
