Dave makes a good point; I also don't recommend opening the cells while
they are charging at a high rate. I like to get SG readings with the
electrolyte being mixed by bubbling, but I turn off the charging
sources, and let it settle down for a few minutes, before opening caps.
And I second Steve's comments: over charging and over filling the cells
can both lead to more problems than EQing might solve.

That does not sound best to me. I get the point but there are much better
ways. Not good for you to be close around a bank in EQ. If you are checking
water level every month the level should not be really low. You do this in
case you miss a cell a month back! You should be counting as the water goes
in to see if you have put about the same amount in. I have never noticed
any advantage to mixing the cells after watering. They will get mixed the
next day. If this concerned you, you could run a 30 minute absorb after
watering.
I like to EQ before watering so my customer does not over fill and start
the corrosion process. Just open all of the cells and look before they EQ.
I also like to mark 2 of the lower SG cells and 2 of the good ones. This
makes it easier for my clients to check the bank. Once every summer or 2
they need to look at all of the cells. Summer is best because it is the
time when you can do long corrective EQ's if you find trouble.

My Rolls manual says:
"It is recommended to water the battery cells half way through the
equalization. This is to
assure the water is completely mixed into the electrolyte."
