My '16 SR5 has 75k miles and is still on the OEM Panasonic battery. It works fine but I plan to replace it in a few months before winter comes and it fails. The car is 6.5 years old since I purchased it. When and what was the mileage when you replaced yours? Should I replace it soon?
How long does the OEM battery last?

I think a battery can be load tested to see how it's lifespan is holding up. I know winter will be the hardest on it and you don't want to get stuck, but I would test it before replacing it with no symptoms of imminent failure. They always seem to give a couple death rattle slow crank episodes before totally crapping out. I would invest in a set of good jumper cables (not crappy light gauge cheapos). They are always good to have on hand, if anything, to help someone else that needs a jump.

This is part of what i was going to post. If you feel like you might have battery issues, I'd get it tested, and also, i'd put a multimeter on your alternator and make sure it's putting out the factory charging numbers (usually around 13-14 volts)
All that aside, i've had batteries last as long as 5-6 years on some vehicles and some cheaper units last less than 3 years. Vehicles on a trickle charger or battery tender can last indefinitely if they're cycled properly.

Jumper cables are great to have for sure. Better yet OP, may be worth investing in something better like one of these Amazon.com: NOCO Boost HD GB70 2000 Amp 12-Volt UltraSafe Lithium Jump Starter Box, Car Battery Booster Pack, Portable Power Bank Charger, and Jumper Cables for up to 8-Liter Gasoline and 6-Liter Diesel Engines : Automotive . I keep one fully charged in my 4R. Had to use it for the first time the other night with my 240z, and holy crap I thought the damn engine was going to fly out of the car with how fast it spun and how long off this thing.

Yeah it's crazy. I also have this big ass jumper box thing that must weigh 30 lbs I used to use. That little noco thing is like..2lbs? maybe? It's a great investment! People always get a kick out of it.

Your friends are probably like "WTF is that thing??"
We have one of those jump boxes as well, but too big and heavy to keep in the vehicle. The little Li Ion do hickey is perfect size. Guess the main thing is remembering to keep it charged.

Replaced the original Panasonic battery in my 17 last year.
This is in AZ which is brutal on batteries (and most everything else)

I replaced the OEM Panasonic in my 2004 (bought in 9/2003) with a Toyota (Interstate) in 11/2015. I still have the Panasonic and it charges up and holds at 12.5 volts. The parts guy said "no, we can't get the Panasonics....wish we could. They are a great battery". I use the Panasonic to jump neighbors' batteries in winter. I keep it on a monitoring battery charger. (BTW, even though the battery is sealed, you can unscrew the little caps to add distilled water if needed.)
The Panasonic was working just fine at the time I replaced it. It was coming into winter and I was pulling a travel trailer down to Florida then over to Texas. We were to be 3 months on the road and I didn't want to have any starting worries. I'm still using the battery I bought in 2015.
I bought a smaller one about palm size and it works well, but can only be used twice when fully charged. Don’t like the usb charger though. Wonder why don’t they include a standard charging cable?

‘18 SR5 w/50,000 miles. Still running the OEM Panasonic. No corrosion, never have serviced it. Truck is regularly used over dirt roads and trails, in snowy winter weather, warm summers.
I bought an ‘02 Tacoma TRD 4x4 pickup new, which had a Panasonic battery. Replaced it in 2009 when the truck had over 100,000 miles on it. It was during winter with subzero weather. If run daily it would start. If attempted without running it the day before, it would just click. I jumped it with my jumper box a few times then replaced it.

This is a question that will get subjective answers.
Factors include - examples:
Battery quality at time of putting in service - even new cars may get batteries months old.
Driving style - how frequent do you drive and do you drive enough to offset the engine start drain, and other drains
Climate - park outside in Florida, no big deal. Park outside in North Dakota - maybe an issue. Summer in ND maybe kinder to a battery than a Florida summer.
In my 2013 FJ Cruiser (bought new in May 2103) my OEM Panasonic lasted until early 2021 (26k miles). I did not drive it much during the Covid fiasco. My other vehicle 2013 BMW 535i, bought new in August 2012, I changed the battery this past week (28k miles) - big 65lb 105AH thing.
So, your mileage will vary.

NOCO jumpers are great. I have a GB40 in my 4R and got it on Amazon during black Friday for I think $65. Well worth the security. Still haven't used it on the 4R yet, but have multiple times on my lawn mower and once on my ATV. I also have an EFI Generac generator that HAS to have the battery full. If I forget to trickle charge it and the power goes out I have backup power to jump it with it. It can charge your phone and everything too if necessary. It's a great thing to have and comes with a car charger too in case you need to charge it back up off grid or something.
