Only got 11 years out of the OEM battery on the Tundra.

$250 for a replacement left me a tad breathless, but as the truck doesn't quite have 69K miles on it yet and will likely last until the kids take my license away, I guess it's a good investment.

The truck has been maintenance free outside of consumables like tires and brakes.

Hmm. I've NEVER had a battery last that long, even in a light-use vehicle.

lol..thats amazing for a oem battery

Both of the OEM batteries in my 2012 Powerstroke finally crapped out last year. That set me back a buck or two.

Just replaced the original battery on a 2013 Equinox. When he asked what kind I wanted, I told him the same one that's there now.

He says, "Oh, they don't make that anymore."

I said, "Of course not. How are you supposed to sell me a new one every 2 years."

"Only"...

11 years is about double the usual lifespan for a vehicle battery!

I think he's messing with us

OP, you are messing with us...right? Normally 3-4, maybe 5 years is what you can expect out of a battery.

That's pretty amazing, did you keep it on a tender?

Nope. Didn't drive it all that much either (obviously, <69Kmiles in 11 years).

I've always had excellent luck with OEM batteries, and I've never had a replacement last more than 3-4 years. Hoping the AGM will break that record.

I worked in the lead-acid automotive battery industry for about 15 years. In plants owned by Gates Rubber, Optima, and Johnson Controls (think Interstate Batteries). All batteries have an expected useful life. A lead-acid battery's life is determined by many factors.
- The more lead and the more acid in a battery, the longer its life.
- Repeated charging and discharging cycles reduce its life. The deeper the cycles, the more the life reduction. Batteries last longer when they are maintained in a state of high charge.

- Electrolyte evaporation rapidly reduces life. Sealed AGM batteries almost always last longer than traditional electrolyte flooded batteries.
- High temperatures rapidly reduce the life of lead-acid batteries. Batteries that are housed in the engine bay, that absorb heat from the engine, that have no outside cooling airflow -- won't last long.

- The high temps of the southern climates reduce battery life faster than the low temps of northern climates. High temps reduce battery capacity, but we normally don't see this as a problem until cold weather arrives. The physics/chemistry of batteries is that they produce less current in lower temps. So...a battery that has compromised capacity, often won't turn over an engine in cold weather -- when low temps compromise current flow even more.
- When the manufacturer uses lead and sulfuric acid with fewer impurities, the longer the battery performs. The battery also gasses less, meaning that it doesn't lose electrolyte as fast as a battery with lower quality lead and acid. Sealed AGM batteries, by their very design, must have higher purity lead and acid.

- A car battery will last a long longer in a temperate climate such as Seattle will last many more years than one in Las Vegas.

 
7 years from my Toyota Tacoma OEM battery. I did replace it proactively, not waiting for it to fail. Now in the 7th year with the Odyssey AGM replacement. I keep the truck in the garage when not driving it, and plug in a maintainer if not going to be driving for more than 3-4 days.

Here in hot S.W. Florida a car battery is good for 3 years. I don’t want to be left stranded with a dead battery so I just date them with a paint pen and switch them out on the 3 year mark.

The original battery in my 2017 Tundra didn't last six weeks, but the warranty replacement is still going strong.

Heck last night the battery on my wife’s Explorer Napa Legend Professional completely died, it was less than two years old. No warning signs, just completely crapped the bed. Luckily, it was covered under warranty and a trip to the Napa store this morning had me walking out with a brand new battery. I guess we live in a disposable world!

Just replaced the CarQuest battery in my wife's Mazda yesterday. It was dated early 2018, so we got 6 years out of it. I didn't think that was too bad. The NAPA replacement I put in it was $206 .

Just replaced a 4 year old (just past the warranty) AGM battery in the Miata. It's about the size of a garden tractor battery and has venting on it because it sits in the trunk. Because it's an odd size, Costco doesn't carry them. I was shocked to find one for $180. Hoping this one lasts longer.

Why are there no dash gauges to warn of a low battery?

Recently replaced the orginal battery in our 2013 Sonata..... Believe some if not all of the car manufactures are in cahoots with battery manufactures as well as others because we no longer have some of the old school "Manual" gauges to show actual real time battery charging / oil pressure / engine temperature. ..... If lucky you might have a "Idiot Light" showing status.... Mostly all electronic dashes that no one pays attention to till it is too late. .................... drill sgt.

The one in my Dodge truck is still going strong since 2012.

I drained it a few times when installing U-Connect and HID fog lights, but seems it may have a few more years to go.

Paul, NAVAIR says SLABs shall be replaced every 24 months.

You scared .
