Car Battery Remote Disconnect Switch with LED Display, 240A 12V Auto Shut Off
Protect your battery, simplify vehicle security, and stay informed with the Car Battery Remote Disconnect Switch with LED Display. Built for 12V systems (also compatible with 24V), this unit is rated for 240A continuous current and can handle up to 500A in surge, making it a robust solution for cars, RVs, boats, ATVs, and trucks. The combination of a magnetic latching relay and intelligent LED voltage display provides secure, energy-efficient battery isolation while letting you monitor voltage in real time. Say goodbye to unnoticed parasitic draw and unexpected no-starts caused by forgotten accessories or long-term parking.
The switch disconnects your battery remotely, safeguarding electronics and extending battery life by preventing hidden power drain. Its magnetic latching mechanism ensures stable disconnection with very low standby current (about 3 mA), so your battery isn’t taxed when the vehicle sits idle. Real-time voltage feedback helps you decide when to start the engine or charge the battery, adding an extra layer of peace of mind during travel or storage. With a negative-ground installation approach, this unit pairs with common vehicle electrical layouts for straightforward setup.
Designed for versatile use and easy retrofitting, this device supports automatic power shut off based on battery voltage. If the voltage falls below 11.8V, the system powers off to prevent deep discharge; when voltage rises above 13.2V, the remote control is automatically disabled to avoid accidental operation. This combination helps protect the battery, wiring, and connected electronics from common faults during long-term storage or busy travel days.
Benefits & Tips
- Preserve battery health during long-term storage by automatically disconnecting parasitic loads.
- Stay informed with the LED voltage display, so you know the battery status at a glance before starting the engine or relaxing at the marina.
- Install confidently with a negative connection design and clear voltage thresholds that reduce the risk of over-discharge or unintentional remote operation.
