Battery not vented
I bought my 13 GS M6 new off the showroom floor. It had been on the showroom floor for a couple months and the battery was completely dead. The dealer replaced the original battery with a brand new battery. The battery is 6 years old and I am going to replace it soon and was looking at it to get the correct model numbers. I noticed the vent line was never hooked up. The battery has leaked hydrogen and sulphuric gasses in the cabin all these years and I never knew about it. I think about it sitting for weeks with the battery tender on, charging the battery with the windows shut, what would have happened if I had lit a match. What did it do to breath these fumes for 6 years? I will never know, it’s hooked up now. If you have the dry sump system and the battery in the back of the cabin check the vent line.

One of the nice side effects of a low voltage battery tender is it uses very little electrolyte as it keeps your battery charged. The Deltran models I have float at about 13.2 vdc which from my experience is about ideal. If anything, you might see some corrosion around your trunk light just above the battery, but I'm willing to bet if you look at it you won't find anything wrong. Incidentally, the byproduct of the charging process is hydrogen gas which won't cause any issues until you try to concentrate it in the correct hydrogen-air mixture.

The amounts of H2 produced would be very small - and it would simply 'float' away ... it is a small/light molecule and is harder to contain than other gases ... up, up and away ... a great fifth dimension song from the 60s - for those old enough to remember - oops, I'm stepping into the stereotype question again. :-)
