Why does everyone not have one of these? Easy install at the battery. Fob added to the keychain. This device isolates the battery preventing any drain and preventing unauthorized startup. Should be used by all the folks that have these car models that are getting stolen. Now, when you isolate the battery everything stops working, like your remote door unlocker, the car radio, etc. Just be warned about that. I have a car that needs juice to the clock, so the clock is no longer set right. But that is a small price to pay. Excellent product.

I had a problem with my 2012 Honda CR-V which had a small parasitic battery drain that would drain the battery over one or two days and I had to literally jump start it every weekend and sometimes it would die when I had to park it you know for longer period of time at the airport. I still didn't want to give up on my Honda CR-V which has over 200,000 miles and I was patient enough to jump start it and sometimes disconnect the battery when I travel out but this device that I've bought has been a miracle you know with the remote it's pretty easy you know I get out of the car lock the car and disconnect the battery and I have a peace of mind that when I get back, my car is gonna start. Works just as advertised and the remotes seem to be pretty good even for a distance of 20 to 25 feet so I'm pretty happy with the purchase.

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.

I've had this for about a year as a band-aid fix for a parasitic draw on my LS swapped RX7. I haven't been able to track down the issue yet and my battery would die after about a week if I didn't drive it enough. After using this for a year and turning the battery off every time I'm done using it my battery has stayed full and have had no issues. It's slightly more expensive then some other alternatives but it was been extremely convenient and worked as advertised with no issues. With my battery being relocated and covered in the trunk it has saved me a great deal of time. Be warned though some settings like your radio stations and other things may not save and be reset using it this way.

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.

It works well, but the batteries that come with/in the remote are garbage. Replace those as soon as you get it and you’ll have a great product. It’s easy to install and works as it should…IF the remote control batteries are replaced.

The media could not be loaded. It works, it’s installed but here’s my critique: A thief will open the hood noticing a dead battery and push the “On” button. This should be be a feature. I understand it is a fail safe, however relays are very ancient tech and are reliable for over a decade. No need for a manual “ON” button. The fitment was awful. My battery tie down, and the cell caps were in the way. I had to finagle things inappropriately out of the way to get it to fit. I also had to flip my Negative terminal as the post provided is too narrow. This box should simply be put on leads that would allow you to hide it anywhere in the vehicle. Something I may do anyway. With leads you could easily attach it to your fuel pump, ignition, ECU etc.. seems a very missed opportunity here. Overall would not buy or recommend for security, only for battery drain.

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.
