With the intAct Battery-Guard and the free Apple or Android app, you can now quickly and easily check the charge status of your battery. Only with a consistent, positive charge state of the battery is full capacity and usability guaranteed. The positive charge state also prevents potential early damage or failure of the battery. After simply connecting it to the battery using ring terminals and downloading the app, you can access the current voltage value. The transmitter is suitable for 6 V, 12 V, and 24 V batteries. The range is approximately 6 meters. The four-color, tachometer-like display shows the charge status in dark green (fully charged), light green (partially charged), orange (discharged), and red (deeply discharged). Additionally, the voltage value is displayed alphanumerically. If the minimum voltage is not reached, a reminder for soon recharging the battery will be issued. With the app, the voltage of up to 5 batteries can be monitored, provided that an intAct Battery-Guard is installed on each battery.
