Here in America people sometimes put aspirin or vinegar or sulfonic acid additive into weak lead acid batteries in hopes of restoring life.
If people in Japan do likewise, then it's possible it could be some of the compounds that would be formed with the additives.
Or, they could be chelates from the EDTA - those would be soluble and tend to crystallize.
As for the insoluble precipitate, that could be lead sulfate, lead particles and lead dioxide that has shed from the plates.
Wishing you well, Mael, in your search to discover what those crystals are.Statistics: Posted by SeaMonkey — Sat Feb 16, 2008 5:51 pm
