Spose you are talking about repair kits for batteries for drill drivers, etc. Yeah they will work. The batteries on the inside are just a bundle of regular batteries wired\soldered together and to the contacts in a specific pattern to deliver the correct voltage to the tool.
You have to crack the plastic case and deal with getting all the alignment correct, good solder joints, etc. then glue it back together.
If you like that sort of stuff go for it. Howvere, I think buying rebuilts or getting someone to do the rebuild for you is probably nearly as cost effective and they will have the experience to do it right.
A quick google delivers http://www.batterypackrepair.com/ and http://www.fixmybatteries.com /

If that is the subject matter, try to get NiMh batteries instead of the old technology Ni-Cad.
The manufacturers wanted planned obsolescence via the cheap batteries. The chargers will do for both. LIon is a diferent horse. Don't even attempt to change the style to one of those. They explode and can be dangerous.

Or are you talking about the books that are about $6? The books are basically going to tell you how to restore a battery with a mig welder.
