CZC AUTO Battery Quick Disconnect Switch Side Post Battery Shut/Cut Off Side Terminal Battery Switch Isolator for Auto Car Truck RV Boat Marine Battery

Good product. Quick delivery.

Works well

No installation instructions may prove problematic for someone not mechanically inclined.

Easy to install, excellent connectivity. Makes removal of a battery connection fast and easy. Quality heavy gauge. May require a steel washer and alternate cable lugs depending on the bolt hole diameter

Easy to install and works great on my trolling motor batteries!

I searched through all (possibly) the similar battery quick-disconnect options on Amazon. Ultimately settled on this one because it stated "solid brass." This is not the case.It is made of weak, pot-metal and painted gold. Also, the "isolator" is a very thin piece of white plastic that barely performs it's function. You must back the screw out, almost completely, to disconnect the battery. At that point, the assembly falls apart (which is why electrical tape is used in my "fix" below).The part snapped on first assembly using only finger strength to get things oriented properly before using the wrench for final tightening. Did not have time to mess with returning/exchanging and finding a replacement, so I got creative with heat shrink and electrical tape. It has worked for four trips needed to move the car around shop and once to gas station, however continuity has become "finicky." Will have to replace before I feel comfortable driving the car any distance.I would not recommend this to anyone.

Doesn’t really cut off the voltage unless you take the knob totally out if the knob is still on it it will still try to make contact and run your battery dead I’m switching over to a switch type to make sure the battery is totally disconnected

It worked like a charm.
