features
Ideal for memory backup
It displays stable working voltage under long light load discharge.
High energy density, voltage 3V
3V (nominal voltage), about twice as much as alkaline button battery and silver oxide battery. It is a battery with high energy density.
Stable discharge characteristics with low internal resistance and high operating voltage
Use high conductivity electrolyte. It reduces the internal resistance and provides a stable working voltage.
Therefore, not only at room temperature, but also at low and high temperatures, the operating voltage has almost no change, showing a stable power.
Excellent liquid resistance and high storage properties
Use organic electrolyte that is not easy to leak. Compared with the battery system using alkaline electrolyte, it has excellent leak resistance.
In addition, the highly sealed sealing structure and sealant treatment achieve a self discharge rate of about 1% per year.
Excellent heavy load discharge characteristics
