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 ________________________________ Message 3 _____________________________________ Time: 03:13:43 PM PST US From: "Henry Trzeciakowski" Subject: Re: AeroElectric-List: Dimmer Control Units Phil: I curious, where on ebay are you selling them?

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.

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.

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.
