After a great weekend at the lake, my start battery has spilled a little acid into the tray. I had it checked and the battery was ok. I think the battery, turned with the caps to the rear, sloshed some be cause of a lot of starts tubing the kids all weekend. After looking around, I'm not satisfied with my options to secure my battery and protect my boat from corrosive spills. The trays will screw down and secure the battery, but only have a short side wall to contain any acid that may spill out. The tie down style for battery boxes lets it move around too much and I really prefer to access the top of my battery without having to remove a top. Are there any high wall trays available? Maybe a box secured in a tray? Thanks, Cliff
