There are the plate chemistries to consider. I doubt this would equalize
thing. Probably make the unequal chemistries worse. Plates would get more
saturated and liquids would get weaker or vice versa.

I have often wondered when connecting batteries in parallel, if sharing
of the electrolyte between batteries (a tube between batteries...??)
would solve the unequal voltage problem.

Any thoughts on this would be appreciated...

thank you for listening to my thoughts.....sno

I was thinking using the same manufacturer/same type battery, sharing
the electrolyte would keep the specific gravity of both batteries the
same.  The plate chemistry would be the same and the electrolyte.

Isn't the specific gravity directly related to charge...?? As long as
the specific gravity is the same, the charges would be the same.

Think about the chemistry that happens when it accepts a charge. The plates
have to have something done to them as well as the electrolytes.

I think swapping electrolytes would leave the plates "yearning" fo whatever
chemistry is owing when they recharge.

Sulphated plates can be rejuvenated quick successfully according to Ghio,
here. I have no experience with this process but I should find out soon. I
have a relatively new bank that is in bad shape from depending on the charge
with PV solely and deep discharging too often.

If sharing electrolyte you would have a single cell not a battery.

Thank you for the help with the terminology I will make a note of it.
