Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V ±0.2V, instantaneous current: 500A. This disconnect switch helps prevent car battery drain caused by long-term parking, line aging, or leaving lights on. It helps preserve battery charge, providing effective protection and extending battery life. Smart 12V car disconnect switch automatically cuts off power after 120 seconds when battery voltage drops below 11.8V to conserve power. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation is then only possible via the manual switch. Automatic cutoff function disconnects power after 120 seconds if voltage falls below 11.8V. Remote control is disabled when voltage rises above 13.2V to prevent unintended power-off during vehicle operation; power can only be controlled using the switch button. This car battery disconnect switch helps prevent power loss due to extended parking, electrical faults, wiring degradation, or forgetting to turn off lights, effectively protecting and extending the life of the car battery.
