But all batteries wear out because lead flakes off the plates and collects
in the bottom of a standard lead/acid battery [that's why the plates do
not extend all the way to the bottom of the case, the space is there to
collect lead sludge. When the sludge touches the plates they short out
and the cell is dead.]


Would sucking out the sludge/flakes, once in a while, extend the life of the
battery? Drain (filter) back any acid/water into the cells.

Has anyone tried this?
