A 12V battery isolator designed to prevent parasitic drain and enable remote power cut-off for cars, campers and boats. Owners gain peace of mind when vehicles sit unused for days or weeks. Is the compact remote-controlled solution from XUZIE Battery Isolator Switch the right fit for your vehicle?

⚡ At a Glance
  • Power Management: Automatic cut-off at 11.9V with ultra-low 3mA standby to avoid deep discharge
  • Best for: Owners of cars, RVs, ATVs and boats who need long-term battery protection
  • Not ideal for: 12V systems with engines over 4.0L or non-standard electrical setups

Operates at 12V/240A with remote on/off control and two remotes included. Designed to simplify battery maintenance and reduce unexpected flat batteries.


Longer battery life – Thanks to ultra-low standby current and automatic cut-off

Monitors battery voltage and initiates a power cut when voltage falls to 11.9V ±0.2V, with a 180-second delay before full disconnect. Standby current is only 3mA, minimising parasitic drain while parked.

Fewer dead batteries during long storage periods and reduced need for jump-starts. Ideal for seasonal vehicles and seldom-used equipment.

Remote anti-theft and convenience – With two wireless remotes for instant disconnect

Includes a wireless remote control system with two remotes for hands-free operation, so power can be cut without opening the bonnet. Safety lockout prevents shutdown if voltage exceeds 13.2V, avoiding accidental cut-outs while driving.

Quickly disable vehicle electronics to deter opportunist thieves and simplify maintenance tasks. Remote control saves repeated manual terminal handling.

Durable, diagnostic-ready design – With corrosion-resistant materials and leakage display

Built from corrosion-resistant components and pure copper wiring to improve conductivity and longevity, and rated to withstand 500A surge currents. Includes a leakage display panel showing Low (0.5–2A), Mid (2–5A) and High (>5A) ranges for basic diagnostics.

Reliable performance in a range of temperatures and load events, with simple visual indicators to help pinpoint parasitic drains. Suitable for harsh marine and off-road environments.

✨ The 4 Key Reasons for XUZIE Battery Isolator Switch
  1. Quick installation - Wiring and fitment often completed in under five minutes
  2. Remote cut-off - Two remotes allow instant power disconnect from outside the vehicle
  3. High surge tolerance - Handles 500A surges to protect against starter current spikes
  4. Leakage diagnostics - Three-stage leakage display helps spot parasitic draws quickly

❓ Frequently Asked Questions

Q: Will it stop my battery draining while the vehicle sits unused?

A: Yes. Automatic cut-off at 11.9V ±0.2V together with an ultra-low 3mA standby current prevents parasitic drain during long periods of inactivity.

Q: Can the isolator shut down while driving by mistake?

A: No. A safety lockout activates when voltage exceeds 13.2V to prevent accidental shutdowns during normal driving conditions.

Q: Is it compatible with my car or boat?

A: Compatible with 12V electrical systems and recommended for engines under 4.0L; fits standard negative terminal sizes of 9-13mm and 15-17mm.

🏆 Our Verdict

Suitable for owners of cars, RVs, ATVs and boats who prioritise battery longevity and simple anti-theft measures. Remote-controlled disconnect combined with low standby draw and diagnostic indicators makes for straightforward, reliable battery management. Strong construction and practical features deliver ongoing value through fewer flat batteries and easier maintenance.
