Specific Gravity varied widely after topping up.

With my Mild temperature swings and the fact that they were close enough to fully charged, I was not worried about the expansion.

They just were not close enough to full, according to my amp hour counter, to take SG measurements where the readings would be comparable to my previous readings of which I have a long list throughout these battery's lives.

My batteries are not the easiest to access. Checking SG is a huge PITA whereas just filling them to near full is just a regular PITA.
