I have never heard of shocking batteries with a taser... I really don't think it would have any sufficient amount of energy to have any effect on the cell whatsoever.

Traditional shock charging involves charging your batteries at an elevated voltage and amperage for a short period of time. The idea here is that when batteries sit for a long time with no charge in them, sulfates can build up on the internal plates and cause them to short out internally or significantly reduce their surface area. Now I have only ever done this on conventional lead acid batteries so I have absolutely no clue how a sealed maintenance free cell will react. With a conventional battery the technique involves hooking it up to a charger with a high amperage "start" setting for about 20 minutes. During this process a great deal of hydrogen gas is produced and it is not uncommon for it to leak electrolyte. This high charge rate forces much more power into the battery than it was ever designed for and as a result the electrolyte begins to "boil". The thermal and mechanical action on the plates removes the sulfation. Again, NO idea how this would work on a sealed battery- my thought is that you could end up rupturing the cell. In any case, if you decide to try this (if AndyMark won't give you a new one or you *need* to try and get one working) then just make sure you do this outdoors in a safe location where if the cell does rupture it will not hurt anyone or damage anything.
