PF---I have a LONG extension cord,so I can get a recharge,at your
house.That way, the electrical bill,goes to you.Seriously,the battery,supposedly,has an(approx)5yr life.Some applications have
a rechargeable battery,so that you don't require another operation.I have to talk that over with the Dr.It's hard to plan,for
these things.I might die tomorrow! Irish
