A Frozen Battery...Can It Be Saved?

| I recently received a large UPS battery box with eight 6 volt sealed
batteries in it.
>From the looks of it, I *think* some of the batteries have been frozen
because of the distorted cases on some of them.
So, can one revive these batteries?
I am thinking on putting a low (2 amp) charge on them for a few days
and see if it works...any other suggestions?
Thanks for any and all suggestions.

If they can't be recharged, any other use for a dead battery? ;< )

Most likely over charged. Seen it many times. Chuck them out.

| Sounds like they may be sulfated beyond recovery. Do a google for the 'Deep cycly battery FAQ'
Cheers

| Thanks for the responses and lead to the FAQ.
I have one on a charger as I type....it is taking a steady 4 amp
charge.
We'll see what develops....
I personally think they are history but it never hurts to try.
Why hasn't someone built a battery that can be taken apart and
reconditioned without going through the whole recycle loop?

1. The mechanical deformation increases the likelyhood of cell shorts going
down the line.
2.Not long after they are put into service, there are large quantities of
crumbly lead compounds of various types floating around inside. The plates
flake. Emptying the electrolyte would be environmentally unsound. The plates
weaken mechanically long before they fail.
3. Forming a battery involves creating a spongy lead layer. That can't be
done in the field.

It isn't cost effective of environmentally sound. Remember that this
is the age when it is cheaper to replace most electronics than try to
fix it. The closest I can think of a rebuildable battery is the old
edison cell (nickel/iron/potassium hydroxide), where the plates are
suspended in glass or ceramic battery jars. These are more historical
items than useful technology, since they self-discharge.

Early automotive lead acid batteries were also re-buildable. I'm
talking even before the pitch-top rubber case units - which were still
rebuiuldable but required more expertese and equipment.
