I go with the Upgraded Diehard, Gold? Best warranty. The C7 Corvette Diehard is the same exact price as the Mercedes-Benz turbodiesel sedan's Diehard. I believe the Diehard in my Diesel is 850CCA! 😳
Here's a pic of my dealer replacement battery from June 2020 and it looks like the same model/part number, but sticker just looks a little different. I recommend cleaning the rust off the neg battery terminal though.
Yours is a Professional Grade AC Delco Battery, 42 months, and that is why the Sticker is different.
I always put the felt pads with the gunga on them when they are new.
As, has been said, I would get rid of the corrosion on the terminal and check to make sure the vent tube and elbow are there.
Nothing wrong with AC Delco batteries.... I have 31 years, 7 Vettes, and 979,000+ miles on OEM batteries.... My '15 OEM gave me 5.5 years --- car had more than 90,000 miles on it....
Not only is there noting wrong with them, they are excellent batteries. I literally bought, sold, warrantied thousands of them through my auto parts. In fact, I sold Exide, Deka and Delco, which all are good batteries, however Delco had the lowest defect ratio. A battery that matches 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 should last 5-6 years. As I stated earlier, I'd be more concerned with the corrosion on the ground stud/nut than the battery.
I've cleaned the corrosion from the stud on the negative cable terminal, and I've found that I have a vent hose in place and attached. I didn't know to look for that when I checked out the battery the first time. Since it's a 30-month battery dated 2020, I suppose it could be as old as 23 months, or as new as 1 or 2 months. I don't plan on buying a replacement just now, but I'll be ready if the need arises.

Both the year and month of manufacturer will be stamped into the battery casing someplace, typically on a side.
The battery in our 2015 (one week old, for us, today) has a 2020 date on it, which I'm happy to see. But, since I know that sometimes when things are changed, the new item is simply 'something that fits', versus being a correct replacement.
From what you can see in these photos, is this battery a correct replacement? And do the various cable and other wire connections appear to be done properly?
TIA, as always,

that battery is what GM will replace it with at dealer. It’s not a problem. Run it till it quits and then get a new battery. My factory battery is 6 1/2 yrs old and still going strong. I drive my car year round and keep a tender on it if I think it’s going to sit for a while. Most batteries are made by a couple of manufacturers. Most are all the same. When you buy a new one get one with comparable AH and CCH to the original. I have had good luck with Auto Zone batteries. I try to buy from someone that is always available wherever I am. Auto Zone is everywhere. So if it goes bad you can get a replacement hassle free. Same with other stores.

Noticed the corrosion on a nut on the ground. There is a hose and fitting om the battery vent and a plug on the other end that vents to the outside of the vehicle. It may not be hooked up.

I believe there are 6 or 7 battery manufacturers currently in the US, I've visited 4 of them over the years. However keep in mind, that just because manufacturers make batteries under multiple brands or retailer's names the batteries are not typically the same.
They manufacturer batteries to the major retailer or brand (Delco for example) specifications not the manufacturer's specifications.
When we replaced the battery in our 2017 last year, GM/AC/Delco had several batteries that physically fit and met the original specs.
A battery guru recommended that even in Chicago, Reserve Capacity was more important than Cold Cranking Amps, in a C7.
People in Minnesota might look at it differently.
We bought the Delco with the highest reserve capacity and longest warranty, I believe it was a 48HPG.

FWIW, went to the dealer today to get a battery and this is the ONLY one in their system for the C7. Maybe it has changed over time but this is the one I bought today.
As a follow-up to my original post, just the other day I received copies of some records from the prior owner's service station, and the battery was installed last July. I should be good for a while.

It is my understanding that the datecode is the 061R that you see on the label. 06 being the month and 2021 being the year (last digit). IF that is true its a June-2021 battery. : )
