Several battery questions for F23

I get the battery discharge warning after just a couple of days of not driving my 2017, so I am pretty sure I need a new battery.

Questions

If I have a battery tender connected will it maintain power while I swap out the battery? Is that safe?

Is the F23 the same battery as the F22?

Will any of the free apps register the battery? If not which should I buy?

Besides Optima, which I have an issue with as a company, what is the best battery to get?

The F23 battery is longer, heavier and has a bit more reserve.

Carly registered my without drama. Well worth the money even though it is subscription these days.

I bought an Oddessy from Battery Mart. Great price quick shipping and as good as OEM or better. Check this thread.

You need to tell the car you have a new battery so that it resets how it charges vs an old battery. should be in the idrive but instead a dealer will charge $100 or more.
