If you can locate an old battery, they can be rebuilt.  I had one done for
me for $51 - new ones are around $100 - 120.  I don't think your idea would
work, but it is at least worth a try.  By the way, if you do want to rebuild
an old battery either yourself or have someone do it, I'll sell you one for
$10, plus postage.  Mailing being cheapest rate possible.  I have two old
ones.   John Brownsberger
