Posting this Battery Maintainer Option that I refer a lot of people to here in Calgary at Jack Carter Chevrolet - Parts Desk.
They sell a lot of these (about $95).
It comes with adapter ends that includes the plug-in for the Corvette C7, GMC Yukon and Cadillac (just to name a few).
I have personally used this on those vehicles. This may sell for less on Amazon depending on shipping fees.







It is recommended that
you purchase a heavier gauge battery cable (separately) to attach to the negative terminal of a loose battery in storage and then clamp to it.
When using the clamps, it is recommended not to directly clamp to the negative post.

I do believe that Amazon has a similar version to this
Battery Maintainer - the SPF3 - however I have not purchased nor tested one from Amazon.

Here’s the scrolling display once connected to a battery and then plugged in

“Analyzing “

“Battery”


"Charging"

12V (confirmed)

95% (on its way to 100%)




Then it scrolls “Full Charged Auto Maintaining”
keeping-it-simple&stupid “kiss”
