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 Chris Brazington

Scary Tightening - my new review

The material is cheap, when tightening it on the battery post, you have to be careful not to bend the jaws to much or they will crack and break.

Pros
  • Works great in our RV
Cons
  • May require frequent maintenance
