If I were you, I'd look for a type MU1R 300 CCA lawn and garden battery from Dekka/East Penn Manufacturing. Can't say if they are available in Maine, as they are manufactured practically in my back yard. I've been ordering them from Lowe's and doing in-store pickup. I run one of these in my Pro8. Yes, they are cheaper.
The battery box on a 5260 may dwarf one of these so be prepared to shim and stabilize as needed.
Edit: Just realized you will likely have to change out your terminal ends if you wanted to go to a MU1R.
Hope the chickens are doing well.
