Buy Battery-Guard Now

With Battery-Guard, you always know if your battery is fully charged or not -  quickly and easily. Don't get stuck with a dead battery!

The Battery-Guard is a Bluetooth device that can be connected to 6, 12 or 24V batteries to enable remote monitoring via smart phone. The free APP is supported by iOS 5, Android 4.3 devices, Windows 10 and higher. With a range of approximately 20 feet, it turns your phone into an accurate voltmeter while eliminating the need for a multi meter or access to the battery terminals.

In addition to a colourful speedometer style visual graphic of voltage level and numeric display, the APP also allows storing of 10 time stamped voltage levels for later review in a graphic format. Up to 10 transmitters can be labelled and connected, with vehicle images, in the APP.

The open ended terminals allow for easy installation on any battery just by loosening terminal hardware. When installed and secured to the battery with the 3MTM adhesive pad, simply turn on your Bluetooth and open the APP – no need to pair the devices. You can then measure the battery voltage, using the auto voltage selection, and assign a name to the transmitter.

Since the device is sensing voltage all the time, you can also use it to check the maximum voltage supplied by your charging system!  A very useful diagnostic.
