Specifications: Battery disconnect switch rated current: 240A, rated voltage: 12V, standby power consumption: 3mA, power-off threshold: 11.8V±0.2V, instantaneous current: 500A. Manual and remote control: This disconnect switch helps prevent car battery drain due to long-term parking, line aging, or leaving lights on. It helps preserve battery charge, providing effective protection and extending battery life. Smart car disconnect switch 12V: When battery voltage drops below 11.8V, the remote switch automatically cuts off power after 120 seconds to conserve energy. When voltage exceeds 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation is then limited to the manual switch. Automatic cut-off: If voltage falls below 11.8V, the remote switch disconnects power after 120 seconds. When voltage rises above 13.2V, remote control is disabled for safety during operation, and power can only be controlled via the switch button. Protect the battery: This battery disconnect switch helps prevent power loss from extended parking, electrical faults, aging wiring, or leaving lights on, effectively protecting and extending the life of your car battery.
