10 year Old Battery?

Since it's April 1st here where I live, I bite. Yes, it's real. The battery should last you another 10 years at least.

 

I’ve reached eight years in a snow plow truck, with a red Optima. I suppose it’s possible, it being properly maintained.

 

I can relate to that as my Interstate Battery lasted 10 years, could have been 11 years or longer as I replaced it thinking my battery was bad but it turned out it was my alternator not the battery.

 

Especially in a warm climate 10 years out of a battery is not unheard of. Especially out of an OEM battery that tend to be better than many of the commonly available replacements.

 

The Sears Die Hard battery in my 308 is now 18 years old and finally giving up the ghost. Sometime you get lucky.

 

I'm on a 3rd one in 28+ years in one of my vintage cars, but it's a 6V system with nothing drawing current after ignition switch is turned "off". While having already several (5-6?) years on it and at times sitting few months without being disconnected or use of "battery tender", it still seem to work as good as the day I replaced it. Never had a 12V lasting quite 10 years.

As for "warranties", a friend bought one with "life time" from Montgomery-Ward(?) over 40 years ago for a car he still has, kept the paperwork and even after multiple product line ownership changes over the decades, he still gets it honored by whoever currently holds it.

 

Batteries tend to last a very long time if they are maintained with a CTEK...

 

My 2009 Audi is on its orig battery.
My previous Dodge Durango battery lasted about 9 years as well.
The more miles I put on my cars, the fewer battery issues I’ve experienced...even in our challenging climate up here.

 

The original factory batteries in my 2004 Porsche Cayenne Turbo (yes it has two) lasted 12 years before one went bad. I decided it was probably a good idea to replace both of them at the same time even though the other was still ok.

 

Battery life is highly dependent on location.

The battery in my Alfa tends to last a long time -- but it's in the trunk, away from heat, and no load when it's off (not even a clock).
I got 14 years out of the last one -- by recharging it with a half-wave battery conditioner every spring.

But the batteries in the Celica GT-Four needed frequent replacement -- sitting ten inches from the glowing turbo.
A number of owners relocated the batteries to the rear -- but they had to used sealed batteries in the hatchback (ST-165).
(Getting the battery out of the way also allowed them to take the sharp bends out of the air intake.)

I think Interstate had a factory problem, a while back.
I've been through two of them in as many years (replacement under warranty).

 

My cars stay on battery tenders, so battery longevity tends to be the case with all of them.

 

Alberto,
I have a 2007 Toyota Tundra as well. It is a USA market one, and I believe manufactured here, and I don't recall the battery make, but I do not believe it was a Panasonic. BUT, it did last over 10 years...about 10.5 years. I just replaced it this past fall. I do all the oil changes on it, and every oil change I would have to top up the water in it...I believe the charging system is slightly overcharging the battery causing this. Anyway, during the last couple years, I included a battery load test at each oil change, and the battery failed last fall, so I replaced it with a new battery from Costco. Interestingly enough, the new battery does not lose electrolyte quite as quickly as the old battery, but I continue to check it with each oil change.

 

Interesting....I noted a 599 GTO that had a battery burst while (presumably) using the factory tender, those are still Ctek no?

 

Yep, I had an Interstate in my Corvette that was around 17 years old when I got rid of it last year. Ended up being a parasitic drain that I figured out and fixed last year that did it in finally. The new battery will last 5-7 years if I'm lucky unfortunately....nothing is made like it used to be.

 

I TEMPT FATE as I write this. This battery was installed in June 2001. That makes it 17 years old. It will probably die the moment I press send. It’s an Optima Yellow Top beneath that plastic tartop cover (they don’t seem to make them like they used nowadays). The car is an MG TC. Image Unavailable, Please Login

 

Now you've done it...RIP MG TC battery!

 

I had an OEM battery located under the boot / trunk, last exactly 10 years (very impressive), and then it failed overnight, this March. I would replace it unless you want to find out how long it will last.

 

Japanese-made Panasonic batteries are the best in the trade from what I heard, but they are not sold in the US to consumers from what I could find. My Nissan 350Z came with a Panasonic battery new that lasted a very long time and I could not replace it with an OEM from the dealer. They only used Johnson Controls brand.

 

I had a battery in an old U Haul truck I own. The thing was well over 20 years old....no idea what brand. That truck would start right away in 20 below weather. Someone swiped the battery about five years ago. I bet that thing is still cranking.
