Car battery life

I've bought/owned several cars and have had to replace batteries in all of them. I can't imagine owning cars and never having to replace a battery in any of them, but we rarely keep cars for less than 5 years. Now with cars transitioning to push starters and auto start/stopping it's even more brutal on the batteries, the AGMs are great but still.
I read an article written by a guy who drove a vehicle with stop/start technology who did mostly city driving. So best case scenario. His average savings amounted to 92 cents/month. Long story short, disable it if you can.
 
My previous car was a hybrid and the regular battery from factory only lasted 26 months, 30k miles. Not the expensive electric drive battery just the regular one everybody has.

I was pretty shocked, I never really kept track of it before but it was definitely the shortest for me in 30 years of car ownership. It’s not even that hot where I am. Just high 50-70 year round and high 80-90 summers.
 
5 years seems about average in Iowa, batteries are one of those things in life that you do not skimp on if you plan on keeping the vehicle for 8 to 10 years.

I had an OEM Ford Focus battery last 11 years. Most others have been around 5 to 6 years. Latest one was both batteries in a Chrysler Pacifica. Turns out if you get the message about auto start stop being unavailable, don't ignore it or you'll have to replace both.

Our hybrid battery lasted 12 yrs & 158K. It wasn't the drive but the start battery in trunk

Toyota guarantees their hybrid batteries for 10 or 12 years from the date of purchase, many go 12 to 15 years before they start to give the owner trouble. Hybrids are a proven technology that is very sound and is not going away anytime soon.
 
Try owning equipment that all has 3 heavy duty batteries and you’re lucky if they last 3 years. Trucks, tractors and combines all have 2-3 batteries. I probably spend $2000 a year on batteries. It seems like I just replaced those batteries yesterday and it has been 4 years and they’re junk.

Yeah, replacing batteries in our RAGBRAI/tailgating bus is not fun. For the record we have a retired greyhound (MC12), not a school bus.

I have always looked at vehicles batteries as rented. What do you want to pay for rent and what kind of a warranty do you want?

Mine has it and you can't disable it. It is now 4 years old and haven't noticed it do it for quite sometime. Kind of wonder if it was because battery is getting weaker. Don't know, I guess.
 
We have it in our Highlander I always thought that it was pointless as hell. You can't tell me I am saving jack on gas.
The Honda Pilot I got last year I guess has it too but even as I've tried listening at stop lights I can't hear or tell when the engine shuts off and then restarts.
 
These newer cars with push start have more expensive batteries with less battery life. Haven’t had to replace mine yet, but I’ve only had the car a year.
 
Just replaced second battery in our van at 3.5 years but probably died because the alternator went out. Previous one was 7.5 years.

I don't think I've ever kept a car for 7 1/2 years because most of my cars before this latest one were used to begin with and never lasted that long.
