ACBungji Battery Disconnect Switch Car Negative Terminal 6V 12V 24V Cut Off Knife for Marine Boat Rv Vehicle (Motorcycle Battery Disconnect Switch-80A)

After installing several electrical accessories to an ATV, I wanted a switch to shut down power for long periods when the machine wouldn't be used. I was looking at more typical battery switches like on larger battery systems. I have one on a boat with two batteries. The battery well on the ATV, under the seat, is space limited though. This small switch sits on top of the battery bolted into one of those terminals with a square nut sitting within it. I find these difficult if you are adding any extra wires/terminals because the bolt then won't reach the nut unless you prop it up with a small wedge like a micro screwdriver or toothpick. The other side of this switch has a nice long bolt for adding multiple wires with ring terminals easily. The simple switch seems to operate fine, just unscrew the knob until power is disconnected. Easy install and the price is right. I used it on the negative side to interrupt the ground but I suppose it could be used on the positive instead. I would recommend it.

Goldwing had a battery draw, didnt wanna diagnose it. This darned thing fit just fine under the panel, works perfectly. Great little added security. You'll wanna get longer hardware than what is supplied with it, but I'm sure you'll figure something out like I did. cheers

This acts as you’d expect; cheap piece of metal that can quickly open the circuit. There is a 90° bend that I found limited my mounting options but I believe most battery terminals shouldn’t have an issue. Good for a cheap solution.

It doesn’t seem cheap and it functions as it is supposed to. Must have for motorcycles that drain your battery.

This was put on our 2020 Waverunner VX Cruiser. When installing, the original battery bolt was too short (I see a few others had the same problem based on their reviews). I noticed there is a nut under the terminal that falls a few cm when the bolt is removed. I put the original bolt back into the nut and slid a zip tie under the nut to hold the nut higher and in place. The original bolt was long enough to catch after that and I simply pulled the zip tie out once it was connected. No extra parts or filing necessary. Works as advertised. Now we'll see if it holds up to my son's riding.

The ACBungji Battery Disconnect Switch Negative Terminal seem to build up carbon or soot so as they sometimes need a bit hard of torquing to get them to reconnect. They work, but not as good as I had expected/desired.

These things are Battery savers, on my newer ATV's And Tractors they discharge quickly if you leave them idle for a while I was jumping them because they didn't have enough pwer to start after istalling these switches I no longer have that problem you just turn the Knob when your done and turn it on again later when you use the vehicle and the battery never discharges. I have purchased 6 of these so far and they work great

Dangerous. The insulating sheath between the two metal bits that the screw is supposed to disconnect is ineffective unless the assembly is perfectly aligned. Budge it left, right, up down, anything, and it re-makes contact without the screw in it.It seemed like it worked. Then I bumped it while the disconnect screw was removed. It made contact and it Kept that contact. Started my motorcycle and let it idle with the disconnect screw removed. I had to wiggle it around hard it get it to lose contact.Whoever designed this had no concept of what it was really intended to do.
