Probably preaching to the choir here and I’m sure not gonna argue with Surrette
But the purpose of equalization is to stir up the electrolyte so you have the same strength from the top to the bottom Some of the older industrial cells had a tube where you could sample it all the way down to the bottom and the top to see what the difference was I have seen them but I’ve never used them in our industry, but it was an interesting thought ! I have heard of batteries where they have taken them apart and had the lower portion of the cells considerably more wore than the upper portion, presumably from the electrolyte being stronger and never having been stirred up by a good charge It seems that came from a class at Trojan many years ago but I could be wrong Just my two cents worth and worth everything that you paid for it !
