I know it's not metric as one has studs that fit a 1/2 inch wrench. Right there is your answer, if its 1/2 inch nut/wrench it's a 5/16 inch bolt.
My batts are threaded 8 mm. Standard wrench size for 8 mm is 13 mm which is almost indistinguishable from a 1/2" wrench.

IF the OP knew the actual battery model, this would provide the answer needed.

On some batteries the positive are 3/8' and the negative are 5/16", others, both are 5/16. I keep a couple of each in the trailer spare parts bin.

OP here
So, I was going to need wing nuts for one of the batteries. Turns out it is stone dead. So, I will see if a local auto service shop can charge it as mine can't. If not,t he need for wing nuts is the least of my worries.

If the battery is too far gone, hook it up in parallel with a good one and then hook up the charger. Some chargers need to "see" some voltage before they will begin charging.
