There are several people on Ebay selling "SECRETS" on how to recondition weak or dead cordless tool batteries. This sounds to good to be true. Since the price of replacement batteries are very expensive I am very interested. Anyone have experience with this?

some batteries can be taken apart (screws) and each individual battery can be tested, and replaced if bad. but they do only have so much life.
You might get a few more months out of one if you drain it down and recharge, but new ones are best.

I have been using all types of cordless power tools for many years. GENERALLY 12 and 14.4 volt tools have longer battery life and charge life. I have all 18 volt cuz I beat the snot out of them, I'm thinking about going to 36 volt even. In my opinion, for just around the house, 12 or 14.4 is best. Unless you plan on ripping down multiple 2x4's the long way, or drilling many 3" holes in thick lumber.

I've revived a few myself. If they no longer charge correctly, I hit them with about 5 volts higher than they are supposed to be - like for only 5 or 10 minutes. Sometimes that is sufficient to get them working again.
After they are chraged normally, I hook them to a car headlight or other load and drain them almost to zero. Charge them again and they work OK for about 6 months.
(These all relates to Ni-Cads. I haven't had any Lithium Ion type give me any trouble yet.)

The eBay thing is a giant rip off. The recharging type of battery has a finite number of charges it'll hold, let's say 1,000 recharges. After that it's toast. Get new ones.
