Test Results-Used T-1275s
(Test Results in a later post in thread page 2) What does the peanut gallery think is the proper SG on a well-used battery? I can never figure out if it is 1.275 but on a reduced capacity, or if ...

What happens BFL13 is an aged battery has had sulfuric acid join with the lead antimony then be shed as particulate matter and gravitate its way to the sediment chamber. The capturing of the H2SO4 or components thereof, dilutes the gravity of the electrolyte. I have seen gray-bearded batteries operating with a 1.255 upper range. With very expensive 2-volt cells I will adjust the density of the electrolyte with concentrate back to OEM density which regains a portion of the lost cell capacity. It's not a miracle treatment but with a five hundred dollar cell it may be worth considering. I call it the "Last Rights" treatment :)
