I Recently obtained a nice very used UPS that was broken, after repairing
the machine I was able to get the charging and inverting circuits working
again. My problem lies in the batteries that it uses are Gel Cells which
a couple of them will only hold a partial charge.  But they do hold a
charge. Two of them hold about 2/3rds normal voltage, and 2 more about
half and one barely holds a volt. These are 6v gel cells.  My question
is, is there any way, like shocking NiCads, to recover full capacity
of these gel cells.

BTW: Replacement cost of these are ~50.00 (us) at Allied, So in the
interest of saving $$ I would be willing to sacrifice some of them
in the interest of experimentation.

Thanks in advance.
