Li cells have more storage in a smaller package so your cordless tools weigh less. They also have no "memory" like a NImh or NiCd.
My venerable Makita set (NiMh) is now packed away in a box with a bad charger and weak batteries. Even using my home brew regeneration method can't bring them back to life.
I bought a Ridgid cordless set because the tools, the batteries, and the charger have a lifetime warranty. I got tired of parking usable tools on a shelf because of bad batteries and failed chargers.
