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 product works amazing my truck has been having a power issue where it kills my battery after installation I've been able to conserve my battery and prevent a theft that's right my truck was broken into and they tried to drive away with it but couldn't start it it does not take up much space the size is perfect worth the money and it's easy to install I love the little remote and build quality is top shelf

It works very well, no complaints. The remote is a very welcome upgrade. Keep the remote in view when installing, or keep a manual cutoff switch in the loop and keep it off during installation: I kept telling my girlfriend not to push the remote's on-button while I was installing only to discover she was accidentally sitting on it lol, but otherwise it remains off on initial power connection until you turn it on. Everything just works - that said, the reason I bought these is because something in each of the cars kept the voltage up, so if your car has this inherent voltage problem, no voltage auto-off switch will work, so if that's also your use-case, you'll always want to use the remote to turn off the car rather than wait for the device to do so, although it does appear to correctly shutoff when the voltage drops: so even if you do forget, the device will still shut off long before the battery is fully drained, so it'll still turn on! Win-win. Also, unrelated to the device's quality, a really good trick is that you can install terminal connectors that screw together and-or have a screw whose point pushes a metal plate onto the post, and both provide a much sturdier connection than regular terminal connectors, and you can fit them onto this device quite easily. If the fasteners are loose on either post, the battery won't charge during use and you may lose power steering/ac/dash/etc, which is not fun, so ensure the terminal connections are secure! Bottom line is that these work phenomenally well, and the first one I bought worked so well, I bought a second one for my girlfriend's car, and they have even held up in the relentless sun. Easily worth the price.

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.

Had to reorder. The 1st one did not turn on. Had to send it back and br replaced. Customer service was top notch and replacement sent as requested. Unit working fine. Thanks for the great service.

This product works great. Has accessories to modify the installation. bought one for my RV and like it so much bought one for my boat

It worked great at first then eventually I had to disconnect it because it started to fail. It didn’t even last a year.

Works like a charm! No more popping my hood every stop to undo the battery. I got this because of a parasitic draw and was skeptical, but it works great.

Was broken, had already been hooked up as a person could see on the terminals . Had no function. Guessing they didn’t read the instructions and hooked it to the positive side not according to instructions..
