With the heat in South Texas I average three years on a battery.

That seems about the same for me and we are near neighbors.

In Florida, I get 24-30 months out of a battery, AGM's included in all of the Expeditions I've had, new 2018 expedition is at 28 months right now.......Heat and I have a lot of stop/starts per day.

But back when I had Fox body mustangs in the 90's with under-drive pulleys and increased ignition timing, batteries would only last a year if I was lucky.

O'Reilly replaced the battery under warranty. It was "probably" bad, but instead of making me wait an hour for a charge test, just gave me a new one and sent me on my way. Good people there.

When do you guys change out your battery?
When it fails or pre-actively?
My wife's battery is 3 1/2 years old, rated at 550 CCA but tests at about 65% (350-ish) but no problem starting.
No cold weather here so that is not a factor.
Go ahead or just wait?

Shortest battery life was maybe two weeks or so. On my '56 Chevy, had a bad regulator and she was putting out mucho voltage. New battery swelled up like a tick.

My dream car when I was about 15-16 (1970).
...carry on

2.5 years on my wifes 2013 Buick Enclave. She called me from the golf course to say her car wouldn't start. I go jump it and try to figure out what light or whatever was left on to wear the battery down. Car was fine next 2 weeks. Then one day she's out again and dead battery. Junk. Put new one in and it's been in for the last 4 years with no issues.

Now assuming that the test was conducted on a fully charged battery, if so, I would change now. That is an early morning headache waiting to happen.

Interior of Alaska (110miles east of Fairbanks) with temperatures of below zero *F and up to an in excess of -40*F/-50*F/-60*F or lower a fully charged battery is critical. All vehicles had a hot plate under battery/ a battery blanket / and a battery trickle charger all plugged into electrical cord or "hitching post". If not plugged in after parking you might get a strong re=start upto 4 hrs time but at 6hrs you could forget it. Also having "block heaters" that keep the blocks warm so the oil will circulate better and faster with a cold block. Actually saw several radiators that froze solid stopping fluid flow while driving down the road causing engine to overheat and fail due to too much air flow unless you placed something in front of radiator to restrict air flow. Even with all of these challanges and others loved my time there. ............................ drill sgt.

3.5 years on the Expedition. Just had to do the wife’s Suburban at 5 years.
The Expedition was really slow cranking. Was not completely dead but it was coming popped a new battery is and no more slow cranks.
With all the crazy electronics in vehicles these days batteries lasting very long is a thing of the past.
I replace batteries with Northstar X2 Power batteries AGM batteries. They a a deep cycle cranking battery and generally have far more cold cranking amps than factory. They also have a 5 year full replacement warranty.

18 months on my old 17 Tacoma it was a balloon. Happy it didn’t pop like some

Truck was well beyond 36k so easier to buy a new one

My experience with OEM Subaru batteries is that they are utter junk. For a vehicle marketed as an outdoor adventure vehicle, the OEM units do not hold up well to even modestly cold temperatures. A common complaint on many Subaru forums. Even brand new, my 2017 3.6L battery would struggle to crank the engine in winter. Replaced it with an Odyssey unit. Expensive, but it turns the engine over as fast in sub-freezing temperatures as it does in the summer.

I have a 2017 Outback with 71K miles. I'm on my third battery and I have a garage. Second two batteries are Interstate from Costco. My Subaru salesman said that one winter, they replaced 17 batteries under warranty.

My ‘16 4Runner is still on the original battery.

That's because the battery, like the car, was made in Japan. I had a 2006 4-Runner, whose battery I replaced at 7 years. It was still doing fine but I was getting paranoid. Due to such fine performance, I replaced with an OEM battery from the dealer. First battery was marked PANASONIC. Second one was marked TOYOTA. It quit after three years.

I have never had an Interstate battery fail before its warrantee period was up. That said, I just replaced an Interstate 24 month (their cheapest series) after 26 months. I think that was the shortest lived battery I have ever had.
I usually buy the high end line but the 24 was all they had at the time and I needed it right then.

I don't think I have ever had one last less than four years.

It's still under warranty, but what a hassle.

What's the shortest lifespan you've ever experienced on a car battery?

about the same on a midlevel autozone battery,

wife's car at the time, (Honda CR-V)
factory battery lasted 7 yrs, new one less than 2, and yes, still under warranty,

the replacement is still in the car (We sold it 2 years ago

About two years- the battery which came with my Tacoma pickup. I replaced it with an Interstate battery.

20 months,
Got replaced under warranty

new impala cop car in 2007. Got it , NEW in Sept. Battery dead in 2-3 months after a -40 night. Battery made in Mexico.

Had the battery in my new 85 Ford F150 last probably 9-10 yrs...I was amazed.

Roughly 2½ years, circa 1988. It was the car's original battery and gave no warning at all. It started fine when I left work, but I stopped for gas on the way home and it wouldn't so much as light a dash light when I went to leave. A funny (as in odd, not amusing) thing about batteries is that they either fail in the first couple of years, or go 5, 6, 7, even more years, with no "in-between." My current car's OE battery went 6 years before showing signs of slow cranking. (I always listen, as well as check dash light operation before starting.)
