Dick,
Yes, hydrogen outgassing is a potential problem, and the area containing
a normal lead-acid battery should not only be protected from sparks and
ignition sources, but should also be vented to the outside.
I would suggest that you look at a larger gel cell or an AGM battery.
If you use a normal lead acid deep cycle battery, you could enclose it
in a tight battery box (often used in RVs) which has a vent hose that
you could route outside.

Wow, thanks to all for the greatly informative answers. I gleaned
many good ideas from them.
This is my concern; I am interested in protecting my K3 from damage by
not being shut down properly should a power interruption occur while
the K3 is operating. For this design, I'm thinking about a worst case
scenario; in transmit mode at 100 watts/20 amps, plus accessories on.
I am concerned about Hydrogen gas while charging a lead-acid battery
here in the furnace room. Since I don't need to operate by battery
power, I'd like to know your thoughts about if a Gel-Cel battery of a
9 amp variety would handle the 20 amp load until I could go to receive
mode and properly shut down?
I haven't had any experience drawing that much amperage from a gel-cel
momentarily. I don't know if the load voltage would be adequate to
keep the K3 alive. I'd need to test it using an older style radio.
I'm hoping someone has had experience related to this.
Thanks in advance for comments,
Dick, n0ce
