Default Low battery

After replacing my old battery on my 2015 corvette with a OEM Battery, I get low battery indicator each starting of the car. How can I reset this?

It is still mad at something. I'd revisit the battery and make SURE all the connections are aligned as they were when they came from the factory AND I'd then confirm that all connections are good and snug. There is a small single wire that has been known to come off it's spot and that could cause issues too.

The cable connections must also be clean... on the inside. Many disregard this and can have trouble even though all looks fine. And, it is not impossible to get a bad new battery. I've done so several times over many decades. Hence, before doing anything else, check the battery voltage at the battery. Good luck!

I apologize if this is TOTALLY wrong. But, does the DIC indicate start battery low or FOB (RKE) battery low? Sometimes the car warns of low FOB battery. Never hurts to consider everything is why I posted.

Us old cars (2014) owners don't have those new fangled messages. I do believe you're correct and the DIC will grump when it senses a low FOB battery too.

I replaced my battery '17GS with and an AGM battery. It showed 12.6 volts new. I drove about 30 miles came home and checked the voltage at the front fuse box with a voltmeter and got 12.6. I wanted to make sure there was no short in the system so I check the voltage for a few days without starting the car. after 4 days it shows 12.4 v.
So what should a good charged battery read?
I ask because I got a txt from the car telling my battery was low?

A resting voltage of 12.4V is roughly 75% charged. This is on the low side.

Good information!!
So I put my trickle charger on via the rear power take-off. After 24 hours I am up to 13.5 volts. What would be the max it "should" be?

Well it pays to double check. I disconnected the charger waited a minute, checked the voltage (at the front fuse box) and got 12.5 volts. So the trickle charger brought it up .1 (1/10) of a volt. Seems more like what a trickle charger should do. Is that logical?
