Airplane Batteries

Sorry if it's a problem here. I just figured if we can discuss hotels
and restaurants, airplane batteries shouldn't bother anyone.

I'll echo the recommendation for posting in r.a.owning. Not because there's
a problem posting your post here, but because you are likely to get better
answers there.

That said, I'll also echo "Viperdoc"'s recommendation for an RG battery. I
think that might be what you mean by "dry". They are sealed, ensuring no
leaks (barring some failure of the battery, of course). They aren't exactly
"dry"...but close enough for your purposes, I think.

Ditto. The reason we have so many groups is that it lets us choose
what what we do NOT want to read. The alternative is for everybody to
post in one giant group where everbody sees everything.

Maybe we should create rec.aviation.hotel-talk .

I'm aware of that. But look at the list of topics on this group. At
least mine was about airplanes.

To those who responded with info, thank you. Much appreciated.

Clearly, discussing airplane batteries is out in this news group.

How ever, it is perfectly permissible to talk about batteries for hotel
emergency lighting.

I didn't mean to pick on Jay, I have no objections to reading his
hotel/restaurant topics.

But his aren't the only non *piloting* topics here -- we have a topic
about two women perpetrating a scam (yeah, that's really about piloting
.... NOT!), guns, and many other non-piloting topics. I didn't see anyone
tell them to post that stuff elsewhere, so yeah, I was just a little
miffed to be told that *my* topic about airplane batteries didn't really
belong here! Obviously many rec.aviation.piloting participants are
airplane owners that no doubt have info about this.

It's not a problem; it's just that you might get more and better responses there.

Compared to all of the other stuff that gets posted, it's close enough.
After all, someone has to pilot that plane, with the battery acid leaking on
their feet! ;-)

IMHO, it's a 50/50 call - it's of interest to pilots, so it's fine here.
However, yes, r.a.owning is another option.

Hey, crosspost to both. g

There are options, such as gell-cell. The problem with the
battery having low acid (liquid) level is that the cell
plates must be submerged in liquid electrolyte in order to
work. If the plates become exposed to air and dry out they
will become useless.
Overcharging will over-heat the battery and boil away the
electrolyte, so installing a voltmeter so you can monitor
that you don't charge above the design limits (12 volt uses
14.5-14.75 as top of the green) and 24 volt uses 26-28 volts
as top, will do a lot to allowing the monitoring of the
battery and charging system.

BTW, aircraft mechanics have to get into all kinds of small
and cramped spaces on a daily basis. Aircraft designers
just assume that their girl friends are dating mechanics and
are trying to get even.

As others have said, the recombinant gas models are sealed units. That's the
only type my Maule was certified to use -- the manufacturer didn't want to run
the risk of having acid spill onto the fabric. I used to get about 4 years
service from mine. In addition to having shorter lives than regular lead-acid
batteries, the RG batteries are very sensitive to being left in a partially
discharged state. Run the battery down and leave it like that for two weeks, and
you'll probably have to replace it.

You will also have to check to see if there's an RG series battery certified for
your aircraft. There probably is, but check the Gill website.
