I have a technical question about voltage and capacity in batteries. I had a dealer tell me my batteries (2 6VDC golf cart batteries connected in series) needed replacing. I checked them with an analog load tester. They checked OK. The repair tech used their digital tester which showed both batteries had 6VDC but one had 78% capacity and the other had 75% capacity. I then took a hydrometer and checked each cell of each battery. One battery showed each cell as good. The other had 2 cells at the mark between good and marginal (the line between the green and white marks). Since both batteries were identical (235AH) how does a battery show fully charged 6VDC but only show 175AH (235*.75)?
