The intAct Battery Check app helps you to keep an eye on your battery together with the intAct Battery-Guard. The Battery-Guard is attached to the battery and transmits the measurement data to the app as soon as your smartphone is connected via Bluetooth. In the app, you can read the battery voltage in volts, the case temperature in degrees Celsius and the discharge state in percent (SoC). These values are also displayed in a history chart where you can select different time periods. You can also use the app to test and retrieve your battery's starting power and charging power. The intAct Battery Check app shows you up to four devices on the dashboard at the same time, notifies you of a critical charge state or unusual starting performance. You can also export the stored data at any time. In the trip overview you can see the times your battery has been charged (corresponding to your trips).
