This has nothing at all to do with fishing . I'm sure a lot have a cordless drill or screwdriver with bad batteries . New batteries are obsolete or cost more than a new drill . Discard the old battery , solder on 10 - 15 ft. lamp cord , add a couple alligator type battery clips ,and you've got a drill you can power off any 12 volt vehicle ...car ,truck ,boat ,lawnmower ,motorcycle ,4 wheeler
