IMAYCC Kill Switch for Car, 12V Remote Battery Disconnect Switch 240A, Car Battery Kill Switch Anti Theft, Automatic Cut/Shut Off Switch for Auto, RV, ATV,Truck, Boat.

This is easy to install. i use it as a disconnect switch when working on electronic stuff on the vehicle so no short-circuits.best of all, it detects a drain on the battery and disconnects it before it is completelly drained. no more dead battery.

I had bought a cheaper one, and that thing destroyed two car batteries. So I spent the extra money and got this one. It works perfectly. Way better than the cheaper one. I have a lowered YukonThat people seem to want to steal and this has totally shut them down. Ipad it six months with no issues.

Update February 2025: The switch has failed after 4 months of use. And it failed oddly: it constantly shows 10.9 volts, just below the 11.0 volt threshold to allow the Jeep to crank. When I remove the switch and connect the battery back to the original leads, the battery shows 12.4 volts, and when running the alternator shows 14.2 volts, so the problem is this switch. I just replaced it with a simple blade switch; no electronics to fail. Cannot recommend this anymore.[Original post in October 2024]So...the first disconnect switch received did not work straight out of the box. But I immediately sought a replacement, which Amazon delivered the next day. I installed it the same way and it works great so far.I'm using this on a secondary vehicle - an old Jeep WJ Grand Cherokee with 300K+ miles. These vehicles were notorious for having tight wiring harnesses that eventually rub and break, causing a phantom draw that discharges (and ruins) the 12V battery. With the mileage that high, I really didn't want to waste time and energy tracking down the shorted wire causing the phantom draw, and this seems like a simple solution. It is...I wish I had found this switch before I ruined a battery.I use the "OFF" feature to disconnect the battery after each drive; this does mean clock time resets each time. I always wait a few seconds (5 - 10) before cranking to allow all the systems to restart, but it works and does keep the battery usable.I have not tried the automatic shutoff feature which leaves the battery "ON" and disconnects the battery when the charge drops too low, but again, this is my back up vehicle. I don't care if the clock resets each time.The black tape on the negative terminal isn't part of the permanent setup. That was just added during installation to prevent shorting/sparking the terminal while tightening the bolts.

This product has been a battery saver! no pun intended. also a great security device as well on our classic cars.

after return the first one that did not work, got replacement that worked as advertised and installed easily on my 1990 jeep, could not make it work on the 1990 mustang .so there are cars that it will not work on even with the adapters

Easy to install and works well!

Works like it said

The idea remote shut off it’s nice but my last only two months, and I was having an issue with shut off by itself sometime even on the stoplight and if you have remote start, sometimes after being shut off, you have to go back in the car turn the key on go back out and remote. Start your car otherwise you won’t be able to do it.
