We have a car with some sort of current leak... if the car is left shut off for a length of time, the battery dies. Unfortunately, humidity, temperature, moon phase, which direction the coyotes are migrating all seem to affect the "length of time". Bottom line, its unpredictable - you might have a dead battery after 20 minutes, or the vehicle might hold the charge for weeks.So - I installed a manual switch on the vehicle. When you wanted to drive, you had to pop the hood, switch the battery on, close the hood... then when you got where you were going, you had to figure out if you wanted to risk a dead battery, or go through the hood/switch/hood sequence again.Being able to do this with a remote is AWESOME. No more hood/switch/hood thing, no worrying about whether the coyotes and moon were in the right paces... just click the remote and the battery is disconnected/connected.The manual that comes with this gadget is absolutely pathetic, and really conveys no useful information. Can you accidentally turn the car off while in motion? Manual doesn't say. Is there a bit of voltage allowed to keep clocks/alarms running? Manual doesn't say (the answer is an unequivocal NO). Connecting the thing is easy enough, but use extreme caution, as there is a lot of unknowns in what can happen.I highly recommend this device but please be careful with the remote, especially when the vehicle is moving.

My old motorcycle circuit has some leakage. Now I install this battery and open it. After using the motorcycle, I press the remote control to solve the leakage problem of my motorcycle.

This is simple to install, and completely resolved the issue with dead batteries in my truck. The two key fobs make it easy to switch the battery on or off. The terminals are removable and rotate both ways, and it fit perfectly in my '99 F-250. I highly recommend this battery cutoff device.

The Csyibeielec Kill Switch is great for vehicle security and safety. This smart switch allows me to remotely disconnect my car's battery, preventing theft or unauthorized use. The 12V design is compatible with most vehicles, and the compact size makes it easy to install. The remote control feature is convenient and reliable. Whether I'm parking in a sketchy area or storing my vehicle for an extended period, this kill switch gives me confidence.

This battery kill switch has become an invaluable addition to my old Jeep. I've always been a bit paranoid about leaving it parked for extended periods, worrying about a drained battery from a faulty light or some other electrical gremlin. This switch gives me complete control, and the added peace of mind is worth its weight in gold. I just flip the switch before I leave it for a few weeks, and I know the battery is safe.

I wanted to have a switch for the secondary battery on the truck so got this- Did a couple tests before installing to make sure it would do what I wanted. in the auto mode it allowed charging and shut off when the batter got under 12v ( I put a small load on the batter and waited for it go under 12.3) the remotes are a super nice touch, might even be a bit of a deterrent if you didn't know the controller was there and tried to steal the vehicle. only *problem* would be if you have a super tight area for install, there was only one way that it would fit on my battery. All in all super nice and Im happy that it does what i need!

After having my battery go dead numerous times because "someone" turned on an overhead light and forgot to turn it off, my son installed this battery disconnect switch. So far, so good, haven't had any incidents that I know of, but one never knows when the lights will be left on, and it's always so inconvenient to have a dead battery. I have high hopes for this little gadget.
