I have the original mine in 2019 but I’m thinking about going to Optima which I know is probably a way better brand. It’s the yellow top one I was going with. What does everybody think?

In the past, I've heard of problems with Optima, enough that I didn't use one. But I can't recall the exact issues, so I'll just say do some research of your own.
For some reason, many people have emotional reactions (good or bad) to discussions about brands of batteries, motor oil, etc.

The OEM battery in my '19 (build date 5/19) died last week. It's my daily, so I never use a maintainer. Checked the forum for rec's which were all over the place. GM dealers, at least the ones in AZ, no longer carry Delco or any batteries. I checked several GM dealers for different size batteries and different model cars. Their online parts catalogs also state "discontinued" too. So I went to Autozone to get a Delco in a different brand case. The good part, was that it has a built-in handle to make installation easier.

I just changed the original battery on my 2017 (build date Sept 2016) last September. So, 7 years. The Exide battery in my previous Vette (02 C5) lasted 7 years. Both garage kept on a battery tender, so 7 years for me...

Mine is a 19 and I am reading through this and other threads looking for battery recommendations. Before I retired I was a Lexus dealer tech so had access to a high end battery tester. I would test my own batteries once in a while and replace when indicated. Now I replace every 5 years. To me the hassle of a car that won't start is just not worth trying to get another year or two out of a battery to save $40.

My 2015 Z-51 C7 Convertible 14,427 miles was built in November 2014, I am the original owner. . My Original Battery is now over 9 years old and still going strong.

6 years for my car, until needing new.

4 to 5 years is a good run.

My OEM battery has 5 1/2 yrs on, been trouble free, however...
I plan to change it once I decide which brand to go with.

I noticed that the Autozone Duralast Gold and the Die Hard 48H6 are identical in spec and design, both have 730 CCA.
I'm guessing they are from the same manufacturer
The AC Delco 48GHR has 40 more CCA and higher cranking amps, it's housing is identical to the Duralast and Diehard
I'll probably go with that since the warrenty is longer (42mos), the price is only $20 more

We sometimes drive to places where a dead battery would be very inconvenient or even dangerous, so I preemptively change at 4 years of the C7.
If your life is such that a dead Corvette would be only a minor inconvenience, going longer can be reasonable. But hot weather is tough on battery life.

CraigStu

The thing I have noticed over the decades is modern cars start really quickly. Oldsters like me remember when car engines had to crank 5 seconds or more before they fired up. That gave one an audible indication if your battery was getting weak, you could hear the slow cranking speed. Not so true today, so often the first indication of a weak battery is when it doesn't crank at all. I don't like wasting $ but $200 now vs $200 a year or two from now isn't going to change my life.

Changed mine after 4 years. Why wait for a breakdown. Battery only a few bucks for peace of mind.

Just tested my cars in spring. Do a load test. Problem solved.

My OEM lasted 7 years. Car new in 2015. On battery maintainer since new.

I've got that kind of life from my MB batteries when they are in the trunk and are used pretty often as a DD. As far as I can see, the tender is there to make sure it doesn't go dead which is a bad thing for the battery. However, if used often and prevented from going dead because you left the lights on or there is a parasitic draw, I don't think the tender does that much or at least, I haven't seen any scientific data other than anecdotal evidence or the seller saying so.

2017 gs w/ 28k. Still have org. Battery . I use the battery tender for when it’s in storage.

My 19 GS has been on the maintainer since new. The battery was installed in July of 2018 when it rolled off the assembly line. Almost 6 years ago and no tell-tale signs of failure. I will probably replace it this spring just for peace of mind.

My battery will be 9 years old the first of April. For the first 5 yrs I drove it almost everyday, till COVID. Since then I drive it at least once a week when the weather is good. It will sit sometimes for a month. The battery has gone completely dead two times. First time during COVID I didn’t think about it. Second time the plug came loose on Corvette charger. Both times I had to remove and put a real charger on it over night. But it’s still working fine. My experience is that the new batteries go dead all at once. In the past they would go down and you could charge them a couple of times before they just quit. Was kind of a warning. The new ones give no warning.

55+ years of car ownership. Decades ago, batteries gave you some warning prior to reaching a state of not being able to crank the engine over. Now for the past 20 or more, batteries are far more prone to sudden death. So replacing on a time schedule seems prudent, longer if you feel lucky!!
