Battery Longevity

[Charmet37]

Hi folks,

Time for a battery replacement and would like to know how long does a car battery usually last? I'm sure there's factors like climate, Short trips and other issues that can shorten a batteries life.

My Acura MDX has been sitting and I haven't started the SUV in a few months and notice there's no crank, Start or power. the battery that was installed was a genuine Acura battery and the date of the battery was September 2019 so that's a seven year old battery, Looks like I need to replace the battery.

What you guys think?

Yes time to replace and make sure you clean both battery terminals.

10 years or more.

Yep, that'll do it.
I have one battery that's about 10 years old and doing fine.

Moving forward, if you want to extend the life of the battery, putting it on a trickle charger at least once a year will greatly extend it's life.
Especially when you know it'll be sitting for an extended period.

Depends. I have had a new agm battery in a Subaru fail within 10 months. Replaced under warranty. Also most recent Subaru original batteries lasted only to 36-38 most (agm). YMMV

A trickle charger will extend battery life by several years. I would add that to the shopping list along with the battery replacement.

I weird this way. I’d have to put a full charge on the battery and see how it performs before buying a new one.

Great idea to buy a trickle charger

I begin to suspect them at 5 years. Sometimes they die at 4... The off to Costco I go!

Charge it and clean the top off of it. The gunk of dust and condensed battery fumes can create a slow short circuit between the terminals.

Being an Acura, I'm sure it has remotes and other gizmos that drain the battery. I'd give it more of a chance than you gave it by ignoring it for a season.

After charging and driving around for a day, put it on a tester. Looks like a Deka which is the best brand.

I average about 7-8 years on my batteries. I do hook up my 2 amp maintainers to every vehicle a few days every month.

My typical OEM battery last 6-7 years on a new car since out of factory. On my hybrid though? It is still going at year 12. Aftermarket stuff from Walmart etc lasted me from 3 years to 5 years usually.
