About this item

【Powerful and Versatile】- The battery disconnect switch is a must-have for protecting vehicles and electrical equipment batteries. With a capacity of up to 125A continuous and 500A crank current, it is suitable for cars, boats, trucks, RVs, and more.

【Enhanced Safety】- Designed to prevent unauthorized use and battery drain, the battery cut-off switch effectively cuts off power flow from the vehicle's battery. This reduces the risk of electrical fire and ensures the battery remains in optimal condition when not in use.

【Convenient Operation】- The battery kill switch is easy to use. Simply engage power by tightening the green knob, and disconnect all power by slightly loosening the knob. Before installation, ensure that the negative battery post and battery clamp are clean for optimal performance.

【Wide Compatibility】- The battery disconnect switch is compatible with most top post terminals (15-17mm cone battery negative post). Please ensure that your vehicle operates at 12V voltage and 125A current and that it utilizes a knob-type disconnect switch.

【Premium Durability】- Crafted from heavy-duty solid brass, the Battery Disconnect Switch is highly resistant to rust and corrosion. This ensures long-term durability and reliable performance, providing you with peace of mind during your battery's operation.

I use this on my boat and my cars not only is it great for security but if you have any little drain on your battery this will fix the problem super easy to install


Great for keeping a vehicle with an slow or unexplained battery drain from killing your battery! fast and easy to turn on and off the battery...


Shuts off car battery with just a few turns of the green knob. Perfect for when towing on a tow dolly that requires ignition key be in the on position to keep steering unlocked. Would also be great to prevent car theft by just taking the green knob completely off the battery disconnect. Good if you want to prevent battery discharge for vehicles that are stored. Works great very happy with purchase.

This is the first Battery disconnect device I have ever purchased. I just purchased a Classic car and a friend of mine sent me the description of your Battery disconnect device.
I like it because I store my car in a commercial facility. They only let you use electrically on an one hour timer. So hooking up a trickle charger is almost useless. Your Battery disconnect keeps the battery from running down and is also a very good security device.


Compact, Easy to Install, and Easy to Use. What a find! Good for storing a car over the winter and keeping the battery fresh.
