I know I need a new battery I bought a $80 one because it was the closest too me but it’s still not the right one so I took it back out and put my old one back in, but it’s dead after sitting for 2 days of course and my battery charger won’t let it charge so i had a dumb question could I use alligator clips from charging my new one to hook up to my quick disconnect that’s on the terminals of my old battery (installed in the bike) to “jump start” it and then leave it hooked to the maintainer until I get a new one? The pictures are the charger with both the quick disconnect clips and terminal rings I’m using
