I decided to try using this instead of a dribbler for my battery in a rarely used car. Instantly disconnected. when I reconnected the battery was still fresh and ready to start car.

Product should have been one piece instead of two. Very poorly engineered . Other similar items are construed as one.

The product is ok. The bolt for the battery is the wrong thread pitch.There are others on Amazon that are correct and will install without getting a new bolt.

When the knob is turned to "disconnect", any movement of the heavy cables will cause random, dangerous, and unwanted reconnections. The original design of this type of disconnect switch made it impossible for this to happen. See the second picture, I have used this type in the past and it is very stable even with heavy cables that want to twist the switch.Also the end of this device that connects to your battery is too thick to reuse the battery post bolt. Not a big deal, just get a 3/8-18 3/4" long bolt. The other end is metric and wont fit your battery. I returned these as unsafe and totally unacceptable design.

The quality of these is just okay but the biggest issue is that the thread pitch for the bolt to connect to the battery is wrong and will not even screw into the battery. This also means that the connection from where the battery cable screws into the disconnect switch is wrong. Because it's a sloppy fit you can actually connect them but you will never get a tight secure fit. And while you will get away with that most of the time. At some point when you need every bit of battery juice to start the engine you're not going to get it. It also increases the likelihood of corrosion on the connections.

I purchased these for a car with an intermittent vampire drain on the battery. It would always disappear whenever I started pulling fuses and metering things. Instead I just got a battery switch. These were very easy to install since they use the factory post terminals. You may need to bend your factory wire a little bit since the post will now be horizontal instead of vertical, but mine was a breeze to do.I first tried a knife style battery switch, but it didn't last long and the connection was getting loose. I have a stereo in my car that can draw upwards of 100amps at once, and I was getting a heck of a voltage drop over the knife switch. No such problem with these screw terminals. They make a really nice tight connection and I don't see any additional voltage drop through them. They also won't wear as quickly because they don't rely on spring action like the knife switches.Had them for about 4 months now with no issues. Will update the review if I find any in future.

The shipping was fast. They look identical to the picture on the website and seem decently well made. They fit fine, went on easy and best of all, a 1/4 turn and no more dead batteries. I mounted it on an old tractor I have. Takes about 5 minutes to install. The screw/knob section is removable for a "theft deterent". I would most likely misplace it if I did that, so that is not an option I will explore, but it is an option if you are so inclined. Happy so far.

So it showed in ad on Amazon that you turn the dial and it disconnects the power. Well it does but then you have 2 pieces and a bolt that has to screw in and out every time. And it is brass so the treads will spaul and jam. I thought this was a switch disconnect. Disappointing. All ready setup the return and ordered different style
