The only way to tell if a battery is discharged, half charged, or fully charged is to check the specific gravity of the acid in each cell- - - -something 90-something percent of the people reading this post will never do.

I guess that I am currently in that 90-somthing percentile.
I have done it before and ruined my jeans. Then for a while a lot of batteries could not be opened to be checked.
Now I don't do it for economic reasons.
I have become such an expert at working on these trucks, that I have had to increase the rate which I am now forced to charge myself for my services. It is now more economical to just buy a new battery.
