=0AHi all,=0A=0AI have a friend with a C-195 that has had a BatteryMinder o
n his battery (Concorde) for the last several weeks. He found a bunch of r
esidue (white flaky stuff) had come out of the battery overflow tube during
this time and was concerned. I assume this is just due to boil-over but a
m looking for more information to give him. Oh, the battery fluid level fo
llowing this was just a hair above the top of the plates.=0A=0AAny thoughts
??=0A=0AThanks!=0A=0AJon

Henry:
Re: My instrument panel is about 80% complete and the next piece of
hardware is
the dimmer system. I've been looking at numerous systems and
controllers:
Is one better than another: i.e. solid state vs using rheostats?
My plan is to have 2 systems: 1 for flight instruments and 1
for
radio/gps/transponder.
What experience or suggestions do you or anyone have....
Rheostats are inefficient in that they convert energy into heat while
dimming. Heat is not a good thing behind your panel. A rheostat can get
so hot that you can smell it while flying. This can be disconcerting, to
say the least.
Solid state units usually have heatsinks, indicating that they are
also inefficient, but not as bad as rheostats.
Other considerations are size. Rheostats are relatively small, while
solid state units are usually 2 pieces (large control circuit with heat
sink and small rheostat or pot in the panel).
The latest unit on the market as you mentioned is the MaxDim. It is
completely solid state and self contained. It fits in the same space as
a rheostat. There is no heat, no heatsink, no space penalty, weighs 1
ounce. It is an FAA-PMA part and STCd for certified aircraft. That means
it has gone through rigorous testing and passed. There is no EMI as with
some other solid state units to interfere with your radio systems.
Extremely easy wiring: 3 wires... Ground, power, and dim.
And now the shameless plug... I'm a dealer for this product and sell
them on ebay below ACS' price.
The other issue re lighting your radios... most radios and some
instruments have built in lighting controlled by a built in photocell
that adjusts its own lighting level. All you do is hook up your system
voltage (12 or 24) to the correct pin and forget about it. It has been
my experience that the instrument/radio manufacturers system works quite
well.

Why not go with all LED technology and control the lights with a simple
reostat?
What am I missing? Skip

It's in the genes of true battery maintainers not
to outgas ANY battery, flooded or sealed. If he's
loosing liquid under charge/maintain cycles from
a Battery Minder, then the charger is defective.
It's easy to tell. A few hours after the Battery
Minder's indicator light turns green . . . measure
the voltage on the battery. It should be 13.8 volts
MAX and ideally about 13.2 volts.

The prototypes are laying on the assembly bench waiting
for the time to get them put together. Where were you planning
on using them?

Hi Bob,
No, it is not an RG battery - just a standard lead-acid battery. Looking at
the Concorde website, I think it is a CB-35A. It is my understanding that
the BatteryMinder is ok for this type of battery. Is that not true??
Ok, will test it further.
Thanks for the input!
Jon
