Just got a new Everstart MAXX H6 from wallyworld. The old one was still going strong but it was a few weeks shy of 8 years old. Install was a breeze, and I kept the old vent plug off the old battery (the new one came with that little plug on the plastic terminal cover). Always had that little vent on the other side (that little white box that attached onto/into the other side vent hole). Only $119.95 plus the fees, and maybe good for another 8 years?
