The battery disconnect switch is a reliable safety device designed to interrupt the electrical circuit of a vehicle when it is parked for an extended period. Using a magnetic release principle, it ensures a safe disconnection of the power source and protects the battery from self-discharge. The device helps prevent electrical failures and costly repairs, while the remote control function allows it to be operated without physical contact.

Main features

  • Magnetic release mechanism Features a modern relay-type control that uses a magnetic principle to interrupt the circuit and precisely controls the flow of power.
  • Low standby consumption The low 3 mA standby current prevents unnecessary battery drain even when parked for long periods in the garage.
  • Automatic power interruption If the voltage drops below 11.8 V, the switch automatically disconnects the power after 120 seconds to protect the battery.
  • Remote control The included remote control allows you to safely operate the switch from a distance without physical contact with the device.
  • Safety against accidental disconnection When the voltage exceeds 13.2 V, the remote control function is automatically locked to prevent accidental disconnection while driving.
  • Professional installation system The negative connection method ensures stable operation and easy installation without complex procedures.

Who is it suitable for and how to use it?

The battery disconnect switch is ideal for cars, trucks, and other vehicles that are parked for long periods. It is perfect for those who want to protect their battery from self-discharge, prevent electronic failures, or avoid a forgotten headlight being left on. It is also useful for drivers who are concerned about old electrical systems or frequent battery replacements due to excessive discharge.

Buyer questions

Q: How does the magnetic release mechanism work?
The switch uses a relay-type control with a magnetic principle that precisely controls the flow of power and reliably interrupts the circuit when needed, protecting the battery from over-discharge.

Q: How is this switch installed on the car's battery?
The device is installed using a negative (minus) connection method, which ensures stable operation and allows for installation without complex procedures or additional special tools.

Q: Can the switch be operated while driving?
No, for safety reasons, when the voltage exceeds 13.2 V, the remote control function is automatically locked to prevent accidental disconnection of the vehicle while in motion.

The battery disconnect switch is a reliable and economical solution that helps extend battery life and protect your car from electrical failures during long periods of inactivity. It is perfect for everyday use and vehicles that are rarely used.

  1. Customer

    It’s difficult to install. It works for now, but it seems like I’ll have to use it for a while to see its durability.
    First of all, it works and it’s really good.
    I highly recommend it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !
    Oh right, this is a photo of the installation of the all-new K7.

    I bought it with distrust that it would work, but surprisingly it does. Installed in a Mercedes 1.8K W211. I have an electric thief, I bought it and installed it right away, it works. I was afraid that during starting with the engine, it would stop working but it’s okay.

    It arrived just 4 days after ordering with fast delivery.
    I attached it to the vehicle, tested it, and confirmed that it was normal.
    It was difficult to install due to the structure of the car, but the operation is perfect, so I hope it can be used for a long time.

    I am using it well.
    It’s great that you can prevent battery discharge in advance.
    The part that attaches to the battery terminal depends on the shape of the battery.
    If you loosen the hex wrench and change the direction, the contact will be better.
    Please refer to this and apply accordingly.
    The remote control’s on/off function is accurate and works well even from a distance of about 10 meters.
    It was an excellent choice to make the purchase.

    It appears to work as advertised.

  15. Customer

    It works well, but it cancels the door lock and you have to open it with the key.

    Question: With Manual Switch

  16. Customer

    A very practical device to prevent draining the battery, works well remotely and makes a small beep. The only comment is that you can accidentally press the buttons and activate the battery.
