Battery Cable Contact Corrosion

After four years of use I have developed significant corrosion on some of
my battery cable connectors.  These are the ordinary bolt on connections.  
I have cleaned them up, but I am curious if there are ways to limit this
corrosion.  I have a well vented battery room and I rinse the batteries
off, any time that I add water to them.  I typically add water more or less
every six months.  The batteries are Trojan L-16Hs.

Coat the bare metal of the connections with a light grease.  I use
vaseline (aka petroleum jelly).  This prevents acid from depositing on
the metal.  Works great on car batts also.

Some will say use oil.  I find that does not seal well enough, must be
reapplied too often, and tends to run and drop.

Some will say use any grease (aka chassis lube or even bearing grease).
I find the heavier greases too thick and hard to get a nice thin coat
that is air tight.  I end up with little pockets of corrosition in the
nooks and crannies (eg deep in the threads under the grease because the
grease didn't go all the way into the crevice).


Sounds like you are doing a good job.

 Batter manufacturers recommend vaseline. We use it at work on our banks. It
protects the connections from acid fumes etc, but most of all it keeps the
air out of the connection and prevents oxidizing due to fumes, acid,
whatever. No oxygen, no oxidization. Easy to wipe off periodically too.

Hi Sylvan,  

"Vaseline" is good for stationary deep cycle battery connections, but
due to it's low melting point, not recommended to be used on starting
(car) or motive deep cycle batteries exposed to engine compartment
temperatures.

Kindest regards,

BiLL.......

Spray paint works, and dries!
