The UMAC Series is said to have high energy storage capacity, low internal resistance, fast charging and discharging and the ability to withstand load fluctuations. It is designed to be used as a secondary battery in the same way as a capacitor. It is also claimed to maintain flat voltage characteristics while accommodating a wide range of load characteristics.
Because of its small capacity and use of chemically stable materials, thermal runaway does not occur. This means that smoke or fire will not occur should a short circuit happen. The UMAC Series has a high rate of charge/discharge cycles and is capable of 10 cycles per hour with a maximum discharge rate of 30mA. It is also said to feature an extended cycle life with a capacity recovery rate of 90% or higher after 1000 cycles.
Besides wearable devices, other uses for the UMAC Series include as a backup power supply for electric home appliances and electronic devices such as mobile phones and information terminals.
