Hi Guys,

Haven't actually had to replace a battery in a Vette since 2009 on my old C6. My 2019 GS was manufactured in 2018 and I bought it in December 2020. I'm thinking I should consider a new battery any time now. All is working well. No slow starts or dead battery issues so far. Gets daily use. Do I have some time, or should I bite the bullet and get it replaced now? I'm hearing/reading good things about Interstate batteries. They have a full 36-month replacement warranty (no prorate) on their AGM battery. I'm still thinking of getting a "wet" battery though... Thoughts guys???

About 4-5 years, typical, for a batteries life. Can be quite a bit shorter if exposed to frequent full or almost full discharges. For me, personally, anything over about 4.5 years is on borrowed time and I'll go ahead and replace preemptively.

The battery in my '15 still has no issues. However, I will change it this Summer to avoid any surprises.

I replace batteries every 5 years as a matter of practical preventative maintenance. Don't over think it. Cheap insurance against getting stranded somewhere.

5 years is a good time to change.

A battery that meets or exceeds power requirements specified by the vehicle's manufacturer, vehicle's charging/starting system has been and is in good condition, battery trickle charged (battery tender) when stored, installed in a vehicle used/stored in a moderate climate will typically last 6+ years. Good idea to start considering battery replacement at 5 years.

I base this opinion on my owning/operating a chain of auto parts stores over 16 years and buying/selling/warranting literally thousands of batteries.

OEM battery in my '15 started showing signs of failure at 6 yrs, 7 months.

Battery life is too varied (same battery, vehicle, etc.) to make a global judgement on replacement time. Don't assume you've one of the "quickies." With C7s many tend to give some electronic indication(s) before dying... but, of course, "Your mileage may vary." All the best, in any event!

I still have the OEM battery in my 16. I don't use a battery tender, but the car doesn't sit more than about a week before drives at most. Only has 14k miles on it, so the previous owner stored it a lot. Mine shows no signs of any issues, but I'll be replacing it this summer before the fall road trip season. Not worth the risk.

Just like I change windshield wipers annually when I get my inspection done. Just an comfortable schedule. Although my vert has never been out in the rain!

I replaced the original battery in my 2014 in 2019 - battery was between 5-6 years old then. I was not having a problem, but just did it as a preventative maintenance type of move.

I replaced the battery in my 2015 coupe at 51 months. I was not having any problems, but I was going on a 2,500 mile trip, and wanted prevent an issue while on the trip.

I replace mine every three years or so. For $175 I consider that cheap insurance. They can be good one day and dead the next. I know I'm probably overkill on this, but I want to be sure to replace the battery at a time that is controlled by me and not the battery.

Best to change it when you pick the time rather than a breakdown choosing the time! A battery lifting device is handy to have on hand if its the original battery with no handle

Jim Barker

The old battery also taxes the charging system more let alone the many other systems that need optimal voltage and reserve!

Kevin A Jones

To me if you systematically change our batteries in your vehicles after apprx 1/2 service life you are wasting quite a bit of money just for a little piece of mind.

I bought a Foxwell BT-705 to try to get a handle on replacing batteries. It provides a lot of info on the battery and charging system. Being able to measure CCAs gives a good idea of battery useful life. Time will tell if this was a good idea. Having six of these large batteries around the house should provide some good info.

If one does not drive a Corvette much... Yeah "wasting quite a bit of money", Is what one may be doing having your Corvette with a new battery every couple of years... for heaven sakes! ... I worry about the Corvette not having enough to eat!... However, for only pennys, tiss a small favour the Corvette asks of us... for its porridge... and the ability to start while in New York city on some filthy, dark wet street at midnight..... . is NOT just for "a little piece of mind"!

The enemies of battery life are infrequent use, complete discharging and temperature extremes. Avoiding those will likely give 4-5 years.
Living in a hot Central Commiefornia climate, I expect to replace batteries every 3-4 years.
I bought a '17 Stingray off a dealer's lot in December, 2017. The car's "born on" date was a year earlier. Six months after purchase, the battery went south, likely from sitting in 100 degree summer heat and not being charged regularly.

Thanks for all the input. Good stuff! I am going to keep an eye on early warning signs and change it before 2022 Fall which would make it 4 years since manufacture date.
