The UMAL has a nominal voltage of 2.3 VDC, can supply 12 mAh with a maximum discharge current of 120 mA and withstands load fluctuations. It has an internal resistance as low as 200 mOhm and can operate over the temperature range of – 20 degrees C to + 70 degrees C.

The nominal charge voltage is 2.7 VDC and the UMAL is capable of fast charging / discharge. In particular the device’s high-rate discharge characteristics mean that a peak-assist capacitor is not required. It also has a charge capacity recovery rate of over 90 % after 5,000 charging cycles. The UMAL measures 2.0 x 14.0 x 21.0 mm.

The device has a chemically stable composition that does not cause a fire or smoke hazard even if the output terminals are shorted out. Mass production will commence in July 2016.
