3C's & a D?

Thanks guys for the suggestion. @Trace 300 Hurst -- your battery looks a lot like the Napa Legend Premium that I have on Medina and Snow White. The latter would have a few more markings to deal with, though:

I've never used one of these, however my first thought was, will this affect venting? I'm sure it's not airtight, just being paranoid. If you look at the legendary battery topper website, they say to use the Delco or Sears maintenance free model's. That one in the picture you posted has raised vents and wouldn't work. You're only a six pack of plastic bottled coca cola classic away from having a vintage battery!
