I've heard of a replace the acid with Alum solution rejuvenation for dead batteries.. I'll look for more concise directions but basically with great care the acid is removed, the sludge at the bottom rinsed out (seems difficult), then the fluid replaced with a saturated solution of alum. charging required 2 or 3 times, the voltage is going to be less by a little but it'll work in the stock system. I got this from another small motorcycle group but not done it myself, I'll look for better directions.

Assuming this battery is dead -other comments are welcomed- where can I get a replacement 6v battery?
It would be great to be able to start it up for folks at the upcoming car show (Oct 22).

This is the one that it had after Mutt restored it about six years ago. After sitting on a 6v battery tender for about a year, it was dead. When we got it started the other day off a big battery charger, we moved it to the garage door and continued. During the move, someone turned off the power strip that the charger had been running off, but the headlight lit for a few seconds before the battery died. There's life in it!!!
I removed the it a few minutes ago. No water, as expected. Before doing anything, it measured 1.6v. After putting distilled water in it, I got 1.5v. It's on the 1.5A 6v battery tender now.
Can this battery be brought back to life, or should I start looking for a new replacement?
