Car battery switch with disconnect function
The battery is dead, even though the car has stood unused for days.
Anyone who parks their vehicle for an extended period knows the result: a drained battery that fails at the worst moment. The smart battery-disconnect switch made of copper reliably interrupts the circuit – manually at the push of a button or automatically – thus protecting against gradual energy loss. The result: the vehicle starts immediately even after a long downtime.

Benefits
- No more dead batteries after downtime: The disconnect switch interrupts the power flow as soon as the vehicle is not in use – parasitic consumers can no longer drain the battery unnoticed.
- No complicated disassembly when parking: Thanks to the straightforward installation process and broad vehicle compatibility, the switch can be operated at the push of a button once mounted – without tools for each application.
- No doubts about reliability in emergencies: The robust copper case is designed for extreme conditions – anyone needing the vehicle again after weeks does not have to hope that the battery still holds.

Specifications
- Function: Manual and automatic power disconnect switch
- Material: Copper
- Compatibility: Wide vehicle compatibility
- Package contents: 1 × Smart battery disconnect switch for cars

Application
- Installation: Attach the disconnect switch directly to the vehicle battery according to the instructions – no special tools required.
- Activate: Before longer downtimes, actuate the switch to interrupt the circuit and protect the battery.
- Turn back on: Before the next ride, reset the switch – the battery is fully charged and ready for use.
Pro tip: For vehicles with many control units, activate the switch after just 24 hours of downtime – modern electrical systems draw continuous power even in standby mode and deplete the battery faster than expected.
