Of course mine is always on the floor which contributed to the paint loss (dragging it around on concrete).

The 7A capability combined with its splash-proof enclosure is one of the reasons I prefer it. I just leave it connected almost all of the time, whether I'm working on the car or not. If I spill something on it (I spilled coolant on mine), I just wipe it off; I can't say that about my Battery Tender Plus. Deltran makes a waterproof Battery Tender, but it's 5A.
I added a aluminum plate on the bottom of the CTEK with 1/2" height spacers.
Was going to match the bottom of the CTEK, but too much time doing it by hand.

1 each Plate 4" x 8" x 1/8" aluminum. (polished with 220 wet paper)
2 each Spacer 3/8" hex, 1/2" height w/ 8-32 male / female.
2 each Nut nylon lock stainless.
2 each Screw 8-32 1/2" counter sink stainless.

Back on the garage floor doing its thing.
