I have a deep discharge battery with a small slow charger I use to provide
a light and fan during power outages.

We had an 11 hour outage last night and I had to go through the pouring
rain and mud to get the battery from an adjoining building. Ugh! BTDT
before.

I decided to start keeping the battery in my mobile home bathroom to avoid
this in the future. The bathroom has an always-open window. Should I be
concerned about trickle charging the battery there?

TIA

Good grief! I'd be worried about the always open window.

The battery, assuming you keep an eye on it occasionally,
I would not be worried about. I hope by trickle charger
you mean a battery tender type of device that monitors and
charges if needed.

My wife keeps one of these things in the bedroom with no problem.

I had one in the hall of my trailer for years.
No problems with hydrogen, or acid.

The float charger from Horrid Fright "boiled"
1 1/2 quarts of water out of the cells and
killed the battery. Much better to check the
voltage with a VOM every week or so, and only
charged if below 12.4v or so.

I don't think your post is off topic at all. You can purchase one of the
newer wall mounted LED emergency lights which is designed to keep a
battery charged for use whenever the power goes out. I'm sure there is
enough power to run a small DC fan too. What I do, is use battery backup
units for computers and other electronic equipment to run lights and
fans when we lose power around my home. I pick up non functioning units
all the time that need new batteries or some distilled water added to
the dead battery to get some more life out of them. I like to recycle
and repurpose old equipment for other uses around the house or for
businesses. ^_^

Don't know why. Unless she's charging it, it is not plugged in.
I've got lead backup batteries on three computers too.

If the battery is
1) charging
2) releasing hydrogen
3) the hydrogen is captured
4) the hydrogen to air mixture is correct
within narrowly defined limits
5) there is a viable source of ignition

Then, it can explode. I've been present for
one battery explosion which was not trickle
charged, not indoors, and the old farmer
wiggled the boost charging clamps to make a
spark.

I've got an old comptuer UPS, been planning to wire that to a car or
trolling battery for extended run. Someday, yes, for sure, someday. At
present I've got a vehicle battery in the other room, just waiting for
its day of use.

Why don't you change to Sealed Lead-Acid batteries. In a pinch, they
can be charged like a normal lead-acid, take constant charging well,
and last a long time. They're the best chemistry for this
application.

I have a bunch of the larger UPS units 750 watt to 1.5 kw that have
external battery connections. You can get the batter plug pigtails from
most suppliers selling computer backup power supplies. You can probably
get an SLA garden tractor battery that has lugs for a reasonable price. ^_^

Figure hydrogen goes up to the ceiling. I agree about the harbor freight
trickle charger, the current could be cut down. I was going to make some
measurements, but on to do list.

I don't think so. The only think that comes to mind is how fast
does the charger charge when the b attery has been used, say for 11
hours, and it's quite low. Is it still only a trickle? I think so.
I think it takes 2 or 3 24-hour days for a battery to fully recharge
when it's fully discharged. I did that many times with a 1 amp
charger. Your trickle charger probably puts out no more than an amp
(although you can measure it and be sure.)

The most importart part is that your window is open all the time.
You're sure? Even in the winter? Even when it's raining? If yes,
I'm 99% sure that makes it safe. (I always leave 1% on general
principles.)

My brother was charging up two 90 or 120 AHR batteries in our boat with
trickle charger. Took ,2-3 months in winter.

Hope the batteries didn't freeze, during that
winter process.

I'd have been tempted to find a faster charger,
rather than risk freeze damage. I had a battery
one time in my unheated shed. My vehicle battery
died, and so I got the one out of the shed. Find
it to be frozen solid. Even after thawing indoors,
it was still useless. Ought have stored it
indoors.

a fully charged battery will not freeze.......

a discharged battery like the one in your shed will easily freeze......

batteries sitting around will self discharge easily

Those are big batteries. It should take a 1A charger well less than a
week from nothing (which a L-A battery should never see) to full
charge. Something was wrong.

If it froze, it was already dead (unless your shed was in Antarctica).

IIRC, batteries (of all chemistries?) keep 90% of their voltage until
they are 90% discharged. I wonder if it is the same on the way back
up, that they have 90% of the rated voltage when they are only 10%
charged.
