    I too had a Duracell leaker. One of the D cells in my ELT let the slime out. The ELT worked, when tested. But the A&P on the field warned me to "look" at them during annual. The cells were three or four years from the expiration date. Had been in the ELT for two years. NOW I check them during every annual. Even checked them for voltage. No leaks, voltage above 1.5V per cell. Just one more data point. Kevin Boddicker Tri Q 200 N7868B 111.5 hours Luana, IA.

    Subject: Re: Duracell Leaking Batteries
    Until recently, I had very few batteries leak, but within the last year, a number have, including one or two still in the package. Little damage to equipment, since I don't generally leave batteries in devices such as camera flashes. I have never had a rechargeable NiMH battery leak. I use those wherever a lower voltage is acceptable to the device. I save up used batteries and take them to the hazardous waste disposal. So I counted the results of the batteries in my discard pile: Leaked/Total Brand 6/18 Rayovac 3/13 Duracell 0/19 Memorex 3/19 Miscellaneous That's a lot of leaky batteries, although some have probably been in the pile as long as 3 years. The Memorex ones seem like a good deal, since they are quite inexpensive in bulk packages. Jeff Page Dream Aircraft Tundra #10

    Thanks... I've emailed Greg at B&C to see if the regulator has been updated, and will post his response for the archives and general knowledge. Etienne On 28 Oct 2008, at 11:38 PM, Robert L.

    Subject: Re: Sub Panel Labeling
    Gentlemen: I've seen numerous e-mails, etc regarding panel labeling, but I really didn't see comments regarding the "COLOR" of the lettering. I've researched thru various FAA sites, etc., and I couldn't find articles as to what the "Legal" color for lettering should be (black, white). I have a meduim Gray Panel (see attachment) and I'm leaning towards BLACK Lettering...it stands out better. I woud appreciate any feedback or suggestions. Henry Pittsburgh, Pa.

    Subject: Re: Sub Panel Labeling
    Greetings Henry, I will be using flat gray for my panel. My experience has been that white stands out much better in a low light situation. I think white will give better readability in low ambient light and allow me to have the instruments lights dimmer which will allow better night adaptation of my eyes.

    Subject: Re: Sub Panel Labeling
    Hi Henry, I don't think there is an actual FAR for coloring of labels, but conventional practice in the business (we do this for a living, so we see it every day) is to use a contrasting color. If the panel is light-use dark labels, if the panel is dark - use light labels. We see the most popular panel colors as Black, Greys, Tan's/Beige and off white colors. If we were building your panel with the color you've attached, I'd really push you towards black lettering for a number of reasons. My 2 cents as usual!

    SteinAir, Inc. a crit : > I'd really push you > towards black lettering for a number of reasons. > I personally would tend to use white against medium gray for reasons of low light visibility. Not everyone has the same perception under such conditions, so I'd conduct some tests in low light : what about visibility at dusk with no panel lights ? What about readability under fluorescent light or whatever is installed/employed for night lighting ? I get the impression that white stand out better than dark figures, just like instrument numbers, but of course others may differ. FWIW, Best regards, -- GillesThesee http://contrails.free.fr
