BATTERY DRAINING WHILE PARKED?
TAKE CONTROL OF YOUR POWER.
Quick battery isolation, solid brass conductivity and convenient rotary control for 12V–24V vehicle electrical systems.
Stop Unwanted Battery Drain.
Disconnect Power in Seconds.
Rotary Battery Disconnect Switch with Voltmeter — a practical battery isolation solution featuring durable conductive materials, easy rotary operation and compatibility with suitable 12V–24V battery systems.




PARKED YOUR VEHICLE — ONLY TO FIND A WEAK BATTERY?
Parasitic electrical draw can slowly drain a vehicle battery even when the engine is off. Long storage periods, unused accessories and inconvenient battery access can make power management frustrating and leave you facing an unexpected no-start situation.
ANTI-LEAKAGE BATTERY DISCONNECT SWITCH
Protect your vehicle battery from unwanted electrical drain by disconnecting it from the vehicle's electrical system when not in use. Ideal for cars and other compatible 12V–24V applications, helping preserve battery charge during parking and storage.

SOLID BRASS & DURABLE CONSTRUCTION
Crafted with high-quality solid brass and conductive copper-alloy components, the switch provides excellent electrical conductivity and corrosion resistance. Durable construction supports reliable battery connections and long-lasting everyday use.

INSTANT POWER CUT-OFF WITH ROTARY KNOB
Disconnect or reconnect battery power with a simple twist of the rotary knob. Convenient for vehicle maintenance, seasonal storage and reducing the risk of unauthorized vehicle operation by isolating battery power.

ADVANCED BATTERY LEAKAGE PROTECTION
When switched off, the battery isolator interrupts the electrical connection to help prevent parasitic discharge and reduce exposure to certain electrical faults while the vehicle is inactive. A practical addition for long-term battery power management.

QUICK & EASY BATTERY TERMINAL INSTALLATION
Designed to mount directly onto compatible 16–19mm battery terminals without complicated wiring modifications. The straightforward terminal-mounted design simplifies installation and makes battery isolation convenient to operate.

CHECK COMPATIBILITY: Confirm your battery uses a suitable 16–19mm terminal and that the switch meets your vehicle's voltage and electrical requirements.
INSTALL: With the vehicle switched off, disconnect the battery safely and mount the switch onto the compatible battery terminal. Secure the connections according to the vehicle's battery service instructions.
CONNECT THE VOLTMETER: If using the voltmeter function, ensure it has the required positive and negative battery connections for correct operation.
CONTROL POWER: Turn the rotary knob to disconnect battery power during storage or maintenance, then reconnect it before normal vehicle operation.
