950 CCA for the 7212 is the largest I see for Napa's offerings -- if it will fit in the tray or hold down. They have several others but are less capacity. A search for battery, sub select Napa batteries, and then 6 volt in the search within results box brings up an even dozen. I know others have had good luck at various tractor supply stores so definitely worth a look if you have any in town.

6.3 volts is what it should read after sitting and calming down after the charge. What will be interesting is what it reads tomorrow. Hook it up and measure, crank the engine and take another reading at the battery while it's cranking and then another after cranking. If it has fallen by tomorrow or can't hold around 5 1/2 volts while cranking and then come back close to the starting voltage it would be suspect.
