Still on original after five years nine months and after being drained down to four volts one night. Restored and charged by a BatteryMinder charger/maintainer I've used for several years. Worth its weight in gold to me. Keeps a raft of 6 or 12 volt batteries (gel, flooded, AGM) going and usable.

7 years is below average lifespan for a battery. I have a 25 year old battery on one of my cars.

 

What is your secret?

 

~4 years....heat down here kills 'em

If one makes it to month 60, I replace it on time like my tires. Jumpstarting is not worth the hassle.

 

IN many cases the OEM on Japanese cars goes a good long time. The 06 I sold last year still had the original. My daughter had an 05 Lexus ES330 she just traded in about a month ago on a 2014 Avalon that still had the OEM but the Avalon with only 65k miles does not.
As for replacement batteries my schedule is typically 3 years. My unknown is Toyota/Lexus branded batteries bought at the dealer. Are they as good as the OEM? My own 11 HL had the oem but prior to my purchase the dealer installed a new Toyota branded one. Also same dealer installed a new one in daughter's "new" Avalon
Life also depends on how well things are maintained, weather and driving conditions and so on

The Toyota TrueStart or True-2 batteries are run-of-the-mill batteries manufactured in North America, similar to other batteries sold in automotive retail stores or Walmart. There are 3 companies that manufacture batteries in the North America: Johnson Controls, Exide, and East Penn.

The OEM batteries on older Toyota's often came from Japan and were excellent quality, and lasted a long time. Part of the reason for that is they had more lead inside the batteries. But now that Toyota is focused on improving fuel economy to meet government regulations coming soon, they are doing everything they can to make vehicles lighter. Lead is very heavy, and a good quality battery can weigh 10 lbs more than cheap one.

 

I changed mine at 5 years whether it need it or not. I did not want to chance a no start condition due to a dead / low battery in the winter. I don't run my tires till the wear bars show either

 

POS OEM Panasonic batteries in both my Highlander and Avalon failed after six months. I normally change mine out at five years regardless, because after that you're on borrowed time. I agree with @Ralph6410

 

Always helps to have a manual transmission, and a light car. My battery in the Mirage is 5.5 years old (7-14 prod date) and I'm looking for a reason to replace it, but I can push start my car myself. Climate and garage kept help.

Takes a good man to push start a car when it's -20 in 6 inches of fresh snow..

 

LOL you need a hill.

 

Assuming mine was the original battery from the factory, 11/2007 - 05/2015. I suspect jumping two or three vehicles finally made it want to die as it did not want to die but I replaced it because upon cold start the engine spun very very very very very slowly before starting up fully. It didn't click, it wasn't just dead, it was just very very slow to start.
