Power tools can make certain task very easy, but they can be pricey. Recently, there have been advancements in the power tools industry. Companies have introduced lithium-ion (LI-ION) based batteries.

Traditionally power tools have been Nickel Metal Hydride (NiMh), or Nickel Cadmium (NiCD). Lithium batteries weigh less. They charge at a much faster rate, however, it comes at a cost.

Recently, the price has dropped on LI-ION power tools. When they first were introduced, you could easily spend over $200 dollars on an 18 volt drill. Now, you can find them for under $200, but in the long run it is not worth it.
