This is something i located when searching for information, I copied it to my web site and will share it with anyone. I want to keep it from getting spidered so this will be a bit of a pain (i.e. no simple cut and pasting of urls)
The base url is http observatory dot attitude net slash 7_730_Motive_Power_Batteries_Manual_Nov_2006.pdf
It shows how to remove the connecting straps without destroying the batteries and shows how to service them as well as refurbishing them. It also shows you how to break up the battery into individual cells.
I am sure others have this document as well but I learned alot from it and maybe someone else will too.
