[RE-wrenches] Strings and series of batteries

[Bill Loesch]

I believe that the granular nature of Quick Coat is the result of having dry baking soda mixed in with the reddish "grease/wax". It was this combination (and perhaps other ingredients in the "special sauce") which provided for the good corrosion resistance performance of this product (and the need to really squash those granules when tightening the connections). Getting down to _bright metal_ (probably accomplished ultimately by wire brush) during every connection (or reconnection) is one key for long lived continuity and maximized battery performance.

  Interstate battery sells a goo called quick coat. (By quick cable). seems to work pretty good. The only problem I've had with it is that it can dry out and get waxy so you need to be sure you clean it all off and reapply it if you need to interrupt the connections. (and don't forget to torque). db

    Everybody has their favorite goo. Ours is Burndy Penetrox, a thick gray paste that we apply with an old toothbrush and work it on good so it's not too thick but everything's well covered. It's much thicker than Vaseline so it never melts or runs. One bottle lasts us a year or two. Terminals that are many years old look like the day they were applied.

It did a good job of protecting the interconnect bars and the cable end connections. Maybe C&D sells this stuff, but I could not find it on their web site.

    >> A device I saw used on an industrial battery bank years ago used a solid brass alloy device. A small oblong plate fits over the battery post, lies flush on the battery case, then the battery cable is attached. A machined brass dome-shaped cover fits snugly over the plate and is attached with small set screws. A grease fitting on the top is where you squirt in special non-corrosive 'grease' until it leaks out around the battery cable opening.
    >> If the cable/terminal connection is good & tight the connection should not corrode or loosen for a decade or more. The device is no doubt pricey but should last for the life of the bank on a quality installation.
    >> I have not ever seen this device advertised, or even thought about it until I read Dicks posting. It sounds like it's worth the investment for an enclosed flooded battery enclosure where fumes will accumulate.
