Monitor Multiple Batteries

Multiple battery monitors can be named and monitored from the one device, so you can keep an eye on an entire garage of cars, check that second battery in your dual battery setup or even the battery in your caravan or boat. You can set periodic notifications of your battery’s condition or set warning notifications when the battery drops below a certain voltage.

Monitor Cranking Voltage Using the OzCharge App you can perform a crank test, this will test the voltage level during the starting sequence of your vehicle. If the voltage is 9.6 or higher, everything is ok. If it’s lower than 9.6 volts, it may indicate there is an abnormality such as an ageing or a damaged battery. The battery charge level is recorded daily and is formulated into a graph over time so that you can stay alert to any trends that may indicate potential battery failure before it’s too late. Run Charging Tests The OzCharge App can also run a charging test which will analyse the effectiveness and health of the alternator. The app will warn the user if the alternator is determined to be unhealthy or showing sub-standard charging performance.
