It used to be when your cordless drill battery died you would toss it in the trash, head to the store, and fork over $80 for a brand spanking new one.

Well, times have changed.

With new Litheon ion batteries out, your cordless drill can last 300x than your old Ni-Cad batteries used to.  But yeah, that's great, but what about when those Litheon Ion batteries die?  And what about your old batteries? Should you really be throwing them away?

• Mig Welder
