As Aquion said, loosening the main nut will destroy the battery. I can
vouch for that as well, not my doing, but I could not recover the batteries
where that had been done. I tightened the nuts and got just about one cycle
before they were gone.

I suspect that the temperature cycling of the batteries enhanced creep of
the case and active materials to the point where there was no longer
adequate compression, and so they are failing. It could be that if they had
mfg them with steel cases and permanent layer level compression they might
have been longer lived.

One thing about being able to take the layers apart is that they are much
easier to move around that way. Each layer is only about 30 lbs. Then you
can find creative uses for the aluminum bases and high strength threaded
rod from them.

If you need an MSDS to show to the disposal site, contact me at AEE Solar.
At our Hazo House locally here, they took a brief look at the MSDS and
said, sure bring them in, no problem. Worth a try.
