RE: rechargeable batteries
Rayovac has the 15 min rechargeable batteries.
They are Ni MH 2000 mah
4 pack is 12.74
The charger with 2 batteries (I dont know why 2 when it charges 4. I guess to get you to buy more batteries) is 27.84
It is supposed to be a smart charger.
I need 6 batteries to start. So i think I am going to spend my $40.
