Huh?
I used 2 batteries.
As I drained one battery, I placed it on the charger and swapped in the fully charged batter.
Used 3 battery CHARGES total. And there was still power left when I was on my third charge.
My guess is you were looking at the batteries I had in the background, I didn't use them, should have moved them out of the shot. I have about 16 total cordless FLEX tools here in the garage, so I have a lot of batteries.
In the real world, you only need 2 batteries. As you drain one battery down, slap it into the charger and put the charged battery into the tool. If you're a worry-wart, get a third battery and never worry.
Sorry for any confusion Howard.
