Was gone for six weeks and came back to a dead battery. Put a trickle charger on it and will see what happens tomorrow. Hoping for the best, but planning for reality. Most posts I’ve found are a few years old, so ....
Assuming I need a new battery, what is everyone replacing their oem battery with?
I changed my 2016 2 weeks ago and got it from battery plus .. Its better because its a AGM battery.... which is... better.. also 10% off and get a core charge of 18 back... I got so much extra CCA that its good for another 10 hp!
A trickle charger may not charge a totally dead battery. Some models need to see some voltage on the battery so proper connection polarity can be verified. A battery charger or a jump may be needed to get a bit of energy in the battery.
If you don't want to stay OEM - Group 48 is the size and you need at least the same 660 CCA rating as the original. I've used NAPA 8448 batteries in 2 vettes and and my DD with no issues. Have any battery you buy tested before you accept it. I've seen a couple dead on the shelf at one of the chain auto parts stores.
Don't forget fob batteries - they are only good for about 3 years. Replace with new, fresh batteries.
I don't recall the numbers, but if you go for the Delco replacements that most dealers sell, and get the higher quality line; there are two versions of "best".
One has the highest cold cranking amps but less reserve amps, the other has higher reserve but less cold cranking.
The advice I've seen is to get the higher reserve version unless you park your car outside in weather below 0'F. I bought the higher reserve version last month, replacing the OEM that had been in the car for almost 4 years. The original was deader than a doornail when the dealer went to get the car out of storage to sell me, a big charger brought it back to life but I'm surprised it lasted this long.

Curious as to what you paid for the AMG battery and it sure would be nice if you could gain HP just by replacing your battery.
Actually, keeping a tender on them whenever they are not in use, especially for a weekend or every other weekend car, will greatly improve battery life. My 2014 may be living on borrowed time, but it is still OK!

It was about $212 after everything and giving them the old one. 48 mo warranty. They did have a cheaper batt if you wanted and more expensive but this is more then enough.
If you drive you Corvette at least once a week, a battery will last a very long time. This is because of the location and it is not subject to engine heat. I took my 11 year old Pontiac G8GT in the other day and asked that they test the 7 year old battery. They said that the battery tested good and there was no need to replace. I replaced the first battery at 144K miles just as a precaution, and since that time, I quit traveling in my job and only drive it about 5K miles a year.
Jumped mine and took it in assuming I may need a new one. It tested low, but good. Was told it should last a while if I drive regularly.
I had the service advisor write on the receipt for an hour long drive a week. (I asked him to put 30 min a day, but he just laughed)

Just keep a trickle charger on it when not driving and you should be fine.

It was a daily driver pre-Covid. Then we escaped the city for six weeks and it wasn’t driven at all. Plan to take it out for mental escape breaks more regularly now.
When dealing with a dead battery, a trickle charge is not the way to go. You need a good strong charger to bring that battery back and then use a maintainer not a trickle charger. The maintainer turns on and off according to what the battery needs and it can be left on for long periods of time. Now with that said letting a battery go dead, even if it is saved will cause it to have a shorter life span. In any event these batteries are a pain to change out. We have a decent dealer here in Az and I had them change my 14 battery out under warranty when is suddenly went totally dead.

I agree.
In my above post I assumed OP had the battery fully charged at the shop where it was tested, if not it needs to be fully charged. Trickle chargers and even alternators are more made to keep charged batteries charged, not to fully charge dead batteries.

I had my C7 for 3 years now and today I got a message on the dash to insert my fob in the fob receptacle in the steering wheel (located where a key in a regular car usually goes in), so I put it there and started the car up. If the fob battery is weak or dead, would putting the fob in the fob receptacle always work to start it up?

The acdelco 42 mo professional model also comes in a HR ( high reserve) model. Cost about $30 more. Lower cold crank amps but higher reserve. Unless you live in an extremely cold climate, high reserve is better suited for modern cars with complex electronic systems.
