I'm curious -- did they sell you what they called an "H7" or a "94R" battery?

My OEM battery died at like 28 months and 20,000 miles.. which is about par for the course here in Florida.. It seems like nearly all my batteries die in the 2-3 year time frame.. Cars, motorcycle..

Personally I think the newer maintenance-free batteries suck. My wife and I each bought a new car in 2005; hers was a Lexus ES and mine was a Nissan Z. Both came with standard lead-acid batteries, the kind with removable cell caps. Proper maintenance required checking the acid level at least once a month and adding distilled water as necessary. Both batteries lasted over 9 years, which is excellent given our upstate New York winters. When I asked the dealers if I could get identical replacements, their answers were no, the Japanese manufacturers put those batteries in their new cars but don't export just the batteries.

AGM batteries can last up to 8 years but suffer disastrously from deep discharge and a failure to recover them properly from the discharge. Even one deep discharge and a high amperage recharge can serious diminish the life of the battery.

Costco here stopped selling the Kirkland branded batteries - they now only have Interstate over in the tire shop, don't know if that's an Arizona thing or they are giving up the branded name and hassles associated with selling batteries (cores and warranties).

We are lucky to get three years out of a battery here - the heat in summer just kills them. I always thought batteries did worse in cold climates but I'd easily get 5 years out of one back east. Fortunately, the guys at Wal-Mart tell you to buy the 3 year free exchange battery and then bring it in at 34 months when it dies. At least you get 2 for 1 and they never even question whether the battery is good or bad they are so used to the short lifespan here.

In a moderate climate you can expect, on average, to get 4-5 years out of a battery. It's a consumable item. As others have mentioned, extreme heat (and cold) is not your friend when it comes to batteries and it can shorten their lifespan. The same goes for a deep discharge (you leave your car parked for a few months or your alternator fails) and then someone using a quick charge to get it back up to operating voltage instead of a trickle charge.

For what it's worth, when I get to 4.5 years or so, I always preemptively change them so I have less risk of getting stuck.

Cheers!

It used to be a thing for import dealers to replace the OEM batteries with cheaper ones when they took delivery of new cars. Then they would resell the take-offs at full price when customers needed batteries. Happened to a buddy of mine who bought a new Honda about 5 years ago. Brand new car and it had a Deka battery when he picked it up. He didn't know the difference. I only noticed when he was showing me his fancy VTEC engine because the ancestral family business used to carry Deka batteries when I was a teenager so I knew it wasn't the OEM part. Now I check when I pick up a new car. :)

Can we test our batteries to see if they are getting close to failure?
You can use an old fashioned load tester on it to see if it's weak, but it will normally still pass one of those tests until it gets very close to the end of its life. Some of the newer chargers can actually run a special trickle cycle that "encourages" the battery to de-sulfate the cathode (or was it the anode...forgot) and sometimes extend the life. In theory, if you keep the electrolytes topped off and you periodically do the desulfation routine, they can last a pretty long time. Hard to do with modern sealed batteries though.

Cheers!

My battery died at about 2 years and 30,000 miles. I had a rough start one evening, then it wouldn’t start the next morning.

On the bright side Roadside assistance came in less than 10 minutes to jump me. It took a few hours for the dealership to install a fresh battery, which was covered by the warranty

I was lucky, got 6 years on the wife's 2012 OEM battery. Replaced with another OEM. Will see if I get close on this one.

Interstate is Johnson Controls, who also makes Kirkland (And Walmart Everstart, and AutoZone Duramax, and others). Might be just a supply issue, they're all the same battery for the most part, and Johnson just sent over the Interstate labeled ones. I don't care what the warranty is, a Standard Lead Acid Battery will last 3-5 years if taken care of. The warranty game is marketing for the most part. In many cases a company sells a 2, 3, and 5 Year battery, and other than the sticker and the warranty, it's the same exact battery.

Hot and Colder areas usually hang in the 3 year range, mid temps will get you 5-6 years.

I've seen this issue where a porter leaves the lights on a car for a month, and kills a battery also. Dealer just pops what they have that'll fit in those cases. Deka/East Penn is a good battery manufacture (usually more on the industrial side). They make the Duracell batteries at Batteries Plus, and Sam's Club (it's weird since Johnson makes Wal-Mart's batteries). They're not considered "cheap" batteries by a long shot, along with Johnson Controls and Exide, they're the "big three" of industrial battery manufactures in the USA.

East Penn does in fact OEM a LOT of batteries though... I've seen their logo on many OEM batteries over the years. They're huge in Forklift batteries...
