battery charger replacement - Stephen Birtles - 07-29-2006 06:24
Well I guess I dont want my batteries charged efficiently but it has
worked wonderfully for the past 6 years and am still working on the
same set of batteries that were installed in year 2000 by the way this
caoch sat for 6 months with no start and no use and when it was
brought out of storage it stared right up with no boost or assistance
So what you are saying is I should tear out this syustem and install
another system that is more efficient.
Sorry but Iam not going to keep up with the the warners in the my
stuff is better engineered and built than your stuff race much luck
with your future endeavours

battery charger replacement - Curt Sprenger - 07-30-2006 08:50
HI Dick,
Been over in AZ and just got home this afternoon. After I get unpacked
I'll take a few pictures and send to your email address.
The rear of the compartment is open as you say, two 5" square openings.
The old boiler fans were facing the openings. The new chargers have fans
are in the front, towards the door.

battery charger replacement - glennshehorn - 05-11-2007 06:52
I really hate to stir up a much discussed (cussed) issue, but with 44
weeks of this treatment left I've got lotsa time and not much energy to
get back to the major projects on my Bird.
I do think I could handle a smaller job that has to be done, so here
goes.
I need to change the original battery chargers out to something that
fits more into the world we live in and won't boil my batteries dry.
Whats the final consensus on this issue. Keeping in mind that the more
projects I come up with( all new plumbing, black and gray water tank
repairs, water heater(s), genset and slide tray, redo headliner,
insulation in doghouse and genset, complete propane system
eval,inverter/converter, air intake mods, plus all the maintenance
issues the previous owner felt were too expensive to do) the lower the
value of my coach gets.
Any and all thoughts greatly appreciated as always.

Final consensus? he he he...
In general, a so-called three stage charger is preferred. One that
provides a high amp "bulk charge" then a medium charge rate as the
batteries become mostly charged, followed with a "float charge" that
holds them at/near a full charge. This can be a separate charger or a
charger that is combined in an inverter. To manage the charger, a
controller is helpful, especially if you have multiple charge
sources, such as shore power and solar panels ... or if you have
plans to add solar panels at a later time.
The recent discussion in the past couple of days of some controllers
is one starting point.
The previous owner of my coach (apparently) upgraded the dual
inverters and installed a Heart Link 2000 R controller that controls
charging batteries in two banks*. I may be mistaken, but it appears
that the house batteries are wired in two banks-- and I don't see
that the engine batteries are in the loop (so to speak) -- but then,
they don't have any load on them between starting the engine.
I need to spend more time tracing battery cables, etc.... when time
and inclination allow...

Glenn,
I used 2 of the IOTA 45 amp, 3 stage chargers in my PT40. Real easy to
install, they use the new charging technology. I see them on eBay for
$150 or so. I installed them last fall, used the coach all winter on
shore power & only added maybe a 1/4 inch of water to them in the last
4-5 months.

Sorry, that came out not quite right. What I meant (I think) was that it seems
to me that the value of these FC's seems to be on a downhill slide. I don't have
the background to know if this is cyclical or it just seems that way as I look
at more work to get it where I want to be on my first Bird. And that IS because
the more I look the more I like. I swear that these units were built with at
least some plan to make an Old Maintenance Man smile and his (fill in the
blanks) go insane.

Twin IOTA 55s work well. Make sure you put in the single IQ4 smart module.
Don't put separate smart modules in. One charger will eat the other. Been
there done that.

Glenn, I hope the 44 weeks go quick and sucessful for you. G.b.
There should be a formula some place on the size of charger necessary
for given/factors A)batterybank B)inverter C)personl need. The
larger the charger the quicker the recharge from gen run when dry
camping. No need buying more than your needs require.
One thing for sure, any charger you upgrade to will some day be
replaced when the nex great battery system is developed. Most
motorhomes dont get upgraded as much as BBlodges. Most dont last as
long.
