2Pcs Auto Battery Terminal Disconnect Master Switch Cut-Off Brass

Not great quality but worksId buy again

Easy to use when not using lawnmower

Used one on my 1967 Chevy. Like to disconnect battery since I don’t drive it right now. I had one of the blade type disconnects on it and they loosen over time. This works really well and doesn’t take up as much space as the older one I was using

We have a couple of older-model cars that often aren't started for many weeks (when we're away from home). For both, the battery ran down, and the car wouldn't start. I bought an (excellent) charger, but that fixes the immediate problem - it doesn't prevent the problem from recurring.Both cars are left outside, so I didn't want to try trickle-charging using a standard electric charger. I did try solar trickle-charging, but that didn't completely prevent the discharge. So, I installed these. Took about 10 minutes to install. I rotated the green handle, to disconnect, and tested using a multimeter. First, I tested red terminal against black terminal - reading was 12.7V (pretty much as expected). Then, I tested red terminal against the "far side" of this disconnector and, to my chagrin, I still saw a voltage reading. It was low (about 1.5V), but FAR higher than I had expected. Happened on both cars. Jiggling the disconnectors didn't do anything. HOWEVER, I left them for an hour, then re-rested - and now it was down to either zero, or very close to zero. And three weeks later, they're still doing well (red vs black, 12.6V).Of course, one disadvantage of this approach is that when you disconnect, you lose all of the "car computer" settings. So, if I turned the green knob, and reconnected, then took the car for a smog test, it wouldn't pass. I would have to drive it far enough for the things to reset. But as long as you're aware of that, then these things are great.

Easy installation, works as described.

Very convenient. Performs as expected. My suggestion would be to increase the thickness of the post that accepts the actual battery cable.Perhaps a sleeve to slide over the post as currently manufactured. It is difficult to tighten the connection sufficiently to give the best possible electrical connection. A GREAT idea so you can easily disconnect your battery power without tools.

I needed a cut off switch for the house batteries in my motor home. The switch was easy to install and works well.

Ordered this product for a classic car that is only driven periodically and I didn't want the battery to drain as can happen with older cars that sit unused. This was very easy to install on my car as the battery is easily accessible. Took only one wrench and less than 5 minutes to complete. A few quick turns of the knob and the power is completely shut off from the battery. A very inexpensive way to save battery life.
