specific value or bubbles fail to rise
even after many hours of charging.
• Sulfation of one or more cells occurs,
as indicated by the plates turning
white, or an accumulation of materi-
ad exists in the bottom of the cell.

slow charge indicate on cell to be low-
er than the rest.
•Warpage or buckling of plates or in-
· sulators is evident.
