Hyper Tough 20V Max Tool Set

It's a cordless set including a reciprocating saw, impact driver, two 1.5Ah batteries, and a charger. All components are 20V Max lithium-ion. Price reflects one of the batteries doesn’t want to charge . Have seen videos on you tube jump starting the battery but don’t know enough to try. Both tools were used for maybe a total of 2 hours if that. Will throw in a brand new 12” Milwaukee blade for the sawzall. Open to trades.
