Morning Dan, As it turns out I was just reading about a product that if true, could be your answer. Check at www.batteryequaliser.com I have some VX-6 battery rejuvenator at home. It is endorsed by Lee Petty. It may be a little old by now huh. I've had some tell me to empty it and refill it with electrolyte. When batteries were shipped dry and filled at purchase, you filled them all the way to the top. Happy Cranking,
