I recently bought a Bosch Cordless Drill. Knowing nothing about drills, cordless, or corded. I learned that years ago people routinely chose the corded drill over the cordless one for the reason — the cordless drill ran out of steam. In addition, it was heavy, the batteries were expensive and it didn't have near the power of a corded drill.
I was delighted when I learned that now, thanks to the Lithium-ion battery (Li-ion); this is no longer the case. Cordless drills are used today not only by homeowners but also by Home Improvement professionals, Woodworkers, and even on large construction sites.

The lithium-ion battery is light years ahead of the earlier batteries and considerably better than the Nickel-cadmium (Ni-Cd) or the nickel-metal hydride (Ni-MH) batteries which are still being used. These batteries are less expensive but the Li-ion batteries are far superior in three ways.
1. Li-ion Batteries are light-weight
A Lightweight battery reduces tool weight so the tool is more comfortable to use and enables you to work longer. My Bosch drill is only 2.2 lbs.; I can take it anywhere and work comfortably for as long as my project takes.
2. Li-ion Batteries last longer and charge quickly
A Li-ion battery and a quick charger make it possible to work all day with a cordless drill without stopping. All you need is two batteries. Put one battery into a quick charger to charge while working with the other battery and repeat the process as long as need be.
3. Li-ion Batteries don't slow down before they stop
Remember how the old batteries would start to wind down before they quit totally? Well, the new Li-ion batteries don't do that. They have the same power when drilling the last screw as they did when drilling the first screw. That seemed amazing to me but I found it to be true.
