Trojan T105 batteries

[INQUISITIVE]

I hope this the place to find an answer to my questions.

I am looking to buy 2 T105's or similar to use as a power outage backup (TV
and a few lights). What I am trying to find out is with just 2 batteries do
I need to worry about hydrogen production or will this be at a minimum for
just the 2. These will be kept in the basement but it is a finished
basement.Will I need to vent these or am I better off to just get gel type
instead.I am trying to get the best bang for the buck so I know gels are
quite a bit more expensive.

Putting them outside in -20C is not an option either

For power backup you will just be float charging the batteries. Depending on your charge current, which can be very low,
you may not have a venting requirement. You want to charge at the very minimum to keep the batteries topped off.
I have 8 Trojan L-16's as a backup to a grid tied pv system. The Xantrex SW4048 inverter floats the batteries at all
times with no apparent gassing. I do not have these batteries vented other than keeping them in a room with the window
open.

No matter what kind of battery you use they will all vent hydrogen gas
when they are charging. Venting will be required regardless.
