Linda asked about some method to bring batteries back to life.
She was on the right track, as older batteries do sulfate, no
longer taking on a charge.
For the EV (electric vehicle), or Home Backup power, there are
some ways of trying to get a battery back to functioning. Basically
chemical treatments (to remove the sulfating), followed by lots
of flushing. Personally I'd rather buy a Optima at $100-125 and
not hassle with acid burns, nor a sore back from lifting the
battery. For an electric vehicle, with dozen batteries, well that
$2000 bill means it is worth getting the correct safety gear and
making a tool to help lift and rotate the batteries.
One source of information was up on HOME POWER web site:

A little digging turned up a couple of articles:

There is also reference to a electronic circuit to help
desulfate batteries. It is in a back issue of the magazine,
but couldn't find the online version.

P.S. When I tried to email Linda at the "lafn.org" email
address, the host will reject messages from all three of
my email accounts!
