Thanks for the suggestions guys, I'm old school and just purchased my 1st Charger/Maintainer. (6V/12V, 1.5 Amp). I've never used one and really had no idea of how much the battery outgassed when hooked up on a constant basis. I do quite a bit of grinding in the shop along with Mig and Gas welding. This project is just starting so I was apprehensive without additional information.
