Re: Drills for ~$100
The Li-ion drills marked "20V MAX" are a bit of a scam. Li-ion cells of the type used in drills have a nominal voltage of 3.6V. 5 cells in series gives 18V. So 20V isn't really possible. More investigation was needed.
I took a long hard look at one of the DeWalt 20V Max drills at Home Depot. In tiny letters on one face of the box read something like:
BATTERIES ARE 20V MAX WITH NO LOAD AND WHEN FIRST REMOVED FROM CHARGER. NOMINAL IS 18V
So Engineering says it's an 18V drill. Marketing says it's 20V MAX.
