He admits that there is a risk of metal hydride batteries exploding when they are re-juvenated using this process.
Cells in a NiCad battery can also explode and may do so some time after being re-juvenated and charged if the cell collapses again. Dendrites ( metal filaments between the plates ) can reform and internally short out a cell. When the battery is then used in a tool the current flowing through that cell could cause the cell to become dangerously over heated.
Also while "dabbing" the wire onto the battery terminal the wire could weld itself to the terminal. If that happens the current through the battery will be dangerously high.

Zapping batteries is a short term fix and as has already been mentioned won't fix cells that have developed dentrites, bit of cell nomenclature is required here to explain more fully.
Typical battery cells are made up of a series of parts, all put together in a small can with a button on top which is crimp fitted to the can with a seperator, this gives us a poss and negative side to the cells from which energy flow in a direction depending on whether it' being charged or discharged. To get the higher charge associated with power tools, this gave birth to the sintered foil used is the most up to date cells being used today, were talking exclusively Ni_cd here. Sintered plates is a clever way of providing a larger surface area so that more energy can be stored on this surface in the form of crystals, than otherwise would have bean capable otherwise and it' these crystals, or rather the size of these crystsls, that is the salient point here.
Matching cells conditioned in this way can be reused to build another battery assuming that they display the same characteristics, for the layman this means same final voltage and energy density (as measured by available Ah) same temperature and discharge slope off (as measured by voltage measurement) at the time of practical discharge.it
Gosh that was a long winded statement, but I just thought I' de put my tuppence worth in...pinenot
