Review on Battery Doctor 20108 Battery Disconnect Knife Switch For Top Post Terminal – 12V Battery Kill Switch For Negative Post – Perfect For Saving Car Battery - Made In USA by Cee Pouncy

Revainrating 5 out of 5

Sturdy and easy to install in the correct application (2002 Mazda Miata).

This is exactly what I needed. It works fine. I used it to stop a parasitic battery leak. It seems sturdy enough. The switch is pretty stiff at first, but I'm sure will smooth out in time. Installation couldn't be easier. Loosen two nuts, tighten two nuts, voila!.

Pros
  • ‎20108
Cons
  • Provides no protection against other forms of battery damage
