Average battery life

[RECHRGD]

I have always replaced batteries at the first sign of weakness.  Usually that occurs at or around the five or six year mark, as I recall.  My '04 Ram 2500 Cummins batteries are still going strong.  I bought the truck new and the batteries (2) still show a green glowing indicator light.  I've never used a battery tender and it can sit for weeks without being driven.  I'm not complaining, as it's about three bills to replace them.  Eleven years is just unreal.  Have I been blessed by the battery fairy or what?

that "green light" is only testing one cell, not the entire battery....average life is 5-7 years, yet I'm still running an Interstate battery in my black 66 from 12 years ago.....

Yes you are blessed. I just replaced my second set of batteries on my 2006 cummins. First two sets where mopar. I now run duralast gold. I change them in pairs too. These diesels hate it when one goes bad. And I wouldn't trust the other one once the first goes. I just do both.
and my wife's Tahoe we bought brand new in 2012, it has 45k on it and the battery took a dump already

The original dual batteries in my 99 Dodge Cummins lasted 12 years. I suspect it had something to do with the high starting currents required by the starter being shared by two batteries. If you look at the grid construction of battery plates high current surges eventually loosen the plate material out of the grid structure causing the battery to fail. Cutting those current demands in half must really help the battery life.

We purchased an 03 stratus R/T new. Last year (in 2015) the battery went as we had a particularly cold winter here. I recall my wife saying, "we have to replace the battery, really??"
I didn't remember if we'd ever replaced the battery but she writes all that stuff down in a ledger of sorts and couldn't find anything.
When I removed it, I found it was the original Mitsu battery that came with the car. 12 years ... frankly I was impressed.

Parts store batteries last about 2-3 years for me. I just had an Interstate go bad on me. That one was in my car 9 years. I am sticking with Interstate.

I swear by Sear's Diehard series.  My typical experience by their batteries is 5-7 years.  I've seen other parts store batteries go out as soon as 3 to 4 years...

I have a 500 amp carbon-pile battery tester, when the needle comes close to the red zone I replace the battery regardless of how it's performing. Never got more than 5 years from one and I usually buy Interstate.

Same here.

Seems like the best batteries ever than were what Dodge was using in 2003/2004.  My 2003 Dakota that I bought new still has it's original battery.  Daily driven with a 155,000 miles and no issues yet.  Our 2005 Chrysler T&C we bought 4 yrs ago had a replacement battery when we bought it and already killed another.  My Charger seems to get the 5-6 range with limited driving and no battery tender.

12 years on a battery?  That's impressive but risky.  Like tires, I replace after 4 or 5 years just in case...

I have an exide gel cell in the 69. Its from 2006

Far this risky now than when I started driving in 92. I always have a cell phone and in this section of indiana almost always have a signal. Plus Walmarts are 24 7. A battery suddenly dieing no big deal.  Feel almost like Kramer seeing just far the tank can go.

you must have more money than you know what to do with I guess

After four, maybe five years my tires begin to develop cracks in their sidewalls; that's grounds for immediate replacement IMO, especially when you consider that all of my vehicles are daily-driver status...

[A383Wing]

tires I can understand....but not batteries getting replaced every 4 years just because...

I had 1/4" cracks in the sidewalls of my black car years ago, the tires still had the little nubbin tit's on the tread....reason for the cracks was car sat outside in the sun 365 days a year back then....I dont think the tires had 600 milers on them at that time, and they were junk

That's the stupid thing about my tire purchases-they always get sun-rotted before I even start to burn through the thread.  None of my cars get driven that much.  I'm grateful for that, but still...

[A383Wing]

then I would suggest you cover up the tires in order to save yourself some money....but like I posted before, you don't listen to what I say anyway....
