I got tired of messing with "Jumper boxes" with junk Chinese agm batteries in them and now have a 200ah motorcycle gel battery with short cables bolted on in a Harbor Freight ammo box.A 12 volt battery of most any size should do the trick.
I like those little black 12v/4.5AHr sealed cubes (used for exit lighting and alarm systems).
Plenty of power and far easier to lug around than a wet cell!

Nice! Mine just has tiny little clips for testing bulbs and powering up the dash when I’m out hunting parts in the bone yards. Can’t crank anything, but doesn’t weigh me down much either, AND they’re under $20...I got tired of messing with "Jumper boxes" with junk Chinese agm batteries in them and now have a 200ah motorcycle gel battery with short cables bolted on in a Harbor Freight ammo box.
I have not come across anything that it would not get going yet.
