    Good job! Plastic dip battery waterproofing (for MagicShine, etc)

    Some battery packs aren't really waterproofed very effectively, so a good plastic dip is in order. This is after 3 coats in Plasti Dip. Seems like decent stuff.

    I will add that you shouldn't overdo it. My batteries fit pretty snug in their nylon pouches now. They still go in with some wiggling, but another coat and I would have been in trouble.

    Nice fix. I sell MagicShines on E-Bay, and wet batteries have been my number one return for warranty. A little silicone sealer on the ends of the pack is a quick and low cost fix, though not as durable as what you have done.

    Just make sure you don't add so much bulk that it will no longer fit in the cloth case.

    Are there different types of dip or just one? I think I might try this.

    I used the liquid tape on both ends of the battery. It is very thin and took several coats. I have the regular plastidip but have not tried it yet.

    with some, you can cold dip or warm dip to adjust for thickness. I cold (<40f) dipped mine to get it the first time. Setting it on a heater vent or in the sunlight would help warm, and thin, the dip. Here in the NE, I left the can outside in the garage for a few hours.

    I did 3 coats of plastidip in 70 degrees weather. It was a very tight fit getting the battery back into the pouch but it is now weather proofed.

    I just finished my 2nd coat. It's about 55*. Too thick - wish I had bought some of the solvent on the can and thinned it out a little bit. way thick on the top. Anyway, it will probably work, but not as well as if it had been 75* out or thinned.

    If you're careful, you can stretch out yor MS battery case just enought to fit a slightly "overdipped" battery.
    Stretch it in each direction gently, (like you would a shirt or baseball cap that just came out of the dryer) and you should be good to go.

    Great news on the taillight Geoman, keep us posted!!
    I'd hit it, but I bruise like a peach.

    Awesome Tscheezy.

    Now tell the people worried about the venting of the battery that this is not a problem.

    I need to waterproof a few batteries and came across this thread. So even though the batteries are susceptible to water, completely submerging them into liquid plastic won't hurt them?

    Do I need to seal anything up on the pack first before dunking them? Seems odd, but worth a shot so long as the results are good.

    Will it void a Geoman warranty? If so can you peel it off?

    If you use Plastidip, no. It is very thick and won't penetrate into the pack.

    Well the liquid plastic, while it is a liquid, is a very viscus liquid (think molasses) that will not penetrate the very small gap at the top and bottom of the battery pack. Waters viscosity on the other hand is almost nil, so it will slip through tiny cracks and openings to short out electronics.

    I put a little black tape around the openings before dipping anyway, just in case.

    Resurrection ------

    Has there been any ill-effects to report with the Plasti-Dip of the batteries?

    I've built a long-run battery for my Cygolite and was thinking about waterproofing these and my MagicShine batteries as well.

    I've found wrapping the battery in cling film to be a good waterproofing solution for the earlier MS batteries. Cheap, light and readily available.

    Any Aussies here that can point me in the right direction for Plasti-dip or similar?

    I have a few Magicshine batteries that need doing as well.

    I rang jaycar but they said it's brush on only and probably not the right product for this.

    I've found a local dealer thankyou (he's only 1600 miles away).

    I'm thinking of trying this Plasti-Dip stuff on my Juicy levers. Lowe's only carries black, but I see multiple colors can be purchased and mixed like paint for endless combinations of colors. Bling and functionality potential?

    Give it a shot. I always go for carbon levers bc riding in cold weather my braking finger gets numb on an alloy lever. Carbon levers make a huge difference there, plasti-dip may work. I like to be able to slide my finger though so not for me.

    I went ahead and used Plasti Dip to waterproof my three Magic Shine batteries last week, and all are working great with no problems. Good stuff.

    The cold is what is driving me. I live (and bike) in four season area - mostly cold season. I had some Lizard Skins that worked well for about a year. They didn't stand-up to the necessary beating. I think the Plasti-Dip will work okay. Easy enough to re-dip after a good endo.

    The 14.5oz tin should be plenty. If it's to late you might check out the new batteries I have for sale on E-Bay. Item number: 270634171268
