PowerGuard AutoCut – Remote-controlled battery disconnect switch

Reliably protects your battery from deep discharge – manually or automatically (depending on the model).

Battery empty after just a few days? Not anymore with the PowerGuard AutoCut!

Forgotten consumers, parasitic currents, or long standstill periods can strain any car battery. The PowerGuard AutoCut disconnects the battery via remote control – and depending on the model also automatically during undervoltage.
This keeps your vehicle ready to start, even after several weeks.

Why our customers love this product

✔ Protects against deep discharge
Depending on the model, the device automatically disconnects the battery at about 11.8 V – before the voltage becomes critical.

One button press is enough: power on/off – conveniently from inside the vehicle.

✔ Versatile use
Ideal for cars, motorhomes, vans, SUVs, boats, motorcycles, and more.

✔ Copper clamps for stable conductivity
High-quality connections ensure secure contact and low heat generation.
