New to battery maintainers, a tad nervous (details inside)

[billj18]

I use a Battery Tender brand maintainer on the deep-cycle battery in my boat, which is stored in my garage. Due to unforeseen circumstances, I ended up without a tow vehicle last summer, so the boat didn't go out. The maintainer has been on the battery for 14 straight months with no issues. The maintainer body and the wall plug are cool to the touch, as are the battery terminals, so no hot spots. If your garage wiring is adequate, I think you are good to go. After all, that's what these devices are designed for.
