Features

  • Practical and Functional: When battery kill switch intelligently detects car battery leakage, it will automatically disconnect the battery main switch and lock 60% of the power for the next start the vehicle, thus to protect the battery and greatly extend battery life.
  • Durable and High Temperature Resistant: The car battery disconnect switch is made of plastic insulated shell and thick copper, the shell is 200 degree heat resistant and copper is highly rust-proof, which makes the switch durable and not easy to deform.
  • Low Consumption: The battery kill switch consumes 0 power when it is in standby, the large silver contacts allow it to withstand 1200A large instantaneous current for 0.1-0.3 second. For reference, the car start current is 200A-300A.
  • Electricity Leakage Display Function: The switch is designed with 3 indicator lights to show different leakage degree, after the vehicle is turned off, the function is automatically turned on. The "medium" light is on, indicating medium leakage 0.5A-2A, "serious" light indicates leakage 2-5A or so, "Super serious" light indicates that the leakage is very serious 5A or more.

    • Battery kill switch
So far so good. Had a drain that could never be found in 2015 honda civic hybrid. This kills the vehicle completely as to not kill the battery every month or two. Only been 1 month so far.

    • I should have gotten this years ago!!
This was bought for my 2012 Jeep Wrangler, due to my battery dying after an unknown amount of time..This is easy to install and works instantly. The fact that it also has a feature that when the battery falls belows 11.9V, it will auto shut off, which will allow you to start up your vehicle (or whatever you have this installed on). ... show more

    • Good Deterrent
Review Image by Virgo Queen Virgo Queen
Good Antitheft deterrent system for a cheap price tag if used in the right conditions, if the vehicle is a newer year and or if it has lots of electronics this isn't for your vehicle, this will totally kill power to the vehicle, basically leaving it in limp mode, so when you activate it everything will loose memories, Like Radio, clock and things of sorts that have constant power running to them, over all a good system for simple vehicles like old school work trucks and vehicle with the least amount of electronics like old JDM vehicles, works and performs as advertised, not bad for price range. ... show more

    • Flimsy
It does what the ad says it does, I installed it today and so far pleased, but it's a little flimsy so be sure to tighten all nuts and posts, mine came very loose

    • Remember to turn it off
Review Image by Rayford Rayford
I had a parasitic drain I couldn't find on my back/sometimes transportation with 275000+ miles. The device put it back in service for my infrequent use. When this car is done I'll move it to my primary vehicle for anti-theft use.

    • It works!
I like that it has a sensor that tells you if you have drain on your battery. Had it for a month works well. Only problem was when stuck in traffic not moving, it would shut off? It would start back up after turning it back on. I think it was getting below 9.6 V. I think if I put it in neutral or park it would let motor rev higher and wouldn’t have that problem. ... show more

    • Unit works, but not the remotes.
The unit was very easy to install and works from the buttons on top. The only issue is that neither remote works and I can’t find any instructions on how program the remotes.
