As I have mentioned before, the terminals need to
be cleaned with sand paper (or a flap sanding
wheel in a 4 inch grinder, carefully.) Then you
need to apply a very light coating of NoAlOx to
the terminals and to the bus bars. Just a thin film of coating is fine.
NoAlOx is the black goop that electricians use
for aluminum wiring connections. They sell it in the hardware store.
You need to sand the terminals because at least
one of them is made from aluminum. It gets an
oxide layer on it almost immediately. Aluminum
oxide is a very good insulator, (unlike copper
oxide which is a conductor, mostly.)

Hey All,
I've been battling low voltage on my cells and
was convinced I had a bad cell. I ordered 4 cells
as spares (since the blue CALB 130 Ah cells are being discontinued).
Well, I replaced once cell and in doing so,
decided to clean the copper jumpers at the same time
(there was a slight bit of blackness on one of the copper jumpers.)
After driving, I found another cell that was
dipping to around 2.6V. I decided to clean the
copper jumpers using my bench grinders wire
wheel. I re-installed and my drop improved to 2.8V
under ~300 amp loads.
So now I'm thinking I need to clean all 50 of my
jumpers and I'd like to put something on the joints.
I've found some old threads on the matter. It
seems like a good idea to put some kind of joint compound
in there since one of the CALB battery terminals
is aluminum and will want to oxidize. I'm thinking
of using this stuff:

any thoughts?
thanks!
