Backup for power failure

I dunno if I would really want to fool with keep ingf a buynch or even
one battery topped off and redy. Not particularly fond of the smell of
electrolyte in a living space or long termin my shop or shed....Gell
cells are an alternative, but still require a trickle charge but are
usuallay not obnoxious when it comes to smell and you do not have that
corriosive vapor getting in the area and causing premature rust, nor
the chance of spilling it and eating holes in the carpet etc. I htink
I would look at sealed, totally sealed gell cells.

I have huge marine deep cycle lead-acid battery in my living
room and it is on the trickle charge: no smells/odors...
