If you're talking about Toyota's "Tru Start" battery, then I had a similar experience. My last one lasted 5 years. The previous one lasted 9. Same type of driving, always topped off with distilled water, etc. Are they no longer made by Interstate?

 

That's why I buy the cheapest batteries I can find. They're just as good as the OEM ones. I just replaced a battery I bought in 2016 that cost $50 at Walmart back then with one that cost $65 online from Walmart. In the store they wanted $150 for the same battery. You DON'T get what you pay for anymore. With all the recycling, you have to wonder why the price doubles and triples these days.

 

Not a unique situation to Toyota, all vehicles have a lot more electronics running all the time, depleting batteries and recharging them, especially compared to your 2005 Corolla. I think five years is a good life for most batteries nowadays, and we just plan on buying a new one at Costco every five years or so.

I like say this as i found out the Toyota batteries are no longer have a long life span . My previous vehicle was a 2005 Corolla and battery i replaced at year 17! I have a 2019 Rav4 limited. That i have had about year. When i got the mileage to about 60k the battery became completely dead. I was often doing what your supposed to. as i do run my vehicle alot on highway as i use it for work as a rural mail deliverer. Anyways after the battery was tested it was proven to be done! I got a new battery from Toyota Dealership and even they said batteries now if your lucky last 5 years Seems toyota now is not about reliability any more when it comes to batteries anyone else have similar situation with this generation of Rav4?
thanks

 

the other reason the battery got toast is i use my vehicle for my job, rural mail delivery, i have like 35 stops on my route and each stop is like a min or less between each other, i was turning off and turning on the vehicle for each stop! as i thought it would save me some gas
now i realized i was just putting more wear on the vehicle afterall.
