All Noraxon sensors have Lithium Polymer batteries. These sensors are rated for a minimum of  300 charge-discharge cycles. Typical usage is 500 charge-discharge cycles. As the number of charge-discharge cycles increases the battery capacity slowly declines thereby reducing run time despite being fully charged.

Brand new batteries for Ultium EMG, Ultium Motion, DTS EMG, and Research Pro IMU sensors can operate for up to 8 hours when fully charged. If the run time of the sensors drops below 3-4 hours or to a level that is no longer suitable for the application, battery replacement should be considered. Only qualified technical personnel may perform maintenance. For battery replacement services, go to https://www.noraxon.com/battery-replacement/.

Brand new batteries for Core EMG sensors last up to 4 hours when fully charged. If the run time of the sensors drops below 1-2 hours or to a level that is no longer suitable for the application, battery replacement should be considered. Only qualified technical personnel may perform maintenance. For battery replacement services, go to https://www.noraxon.com/battery-replacement/.

NOTE: Battery replacement for Ultium EMG sensors is offerred completely free of charge. A quote for battery replacement of other sensor types based on the quantity is given in the battery replacement form.
