The Premium button battery is a compact, light and economical alkaline battery with a nominal voltage of 1.5V. The LR (alkaline) battery is less expensive than SR (silver oxide) batteries and is practical for a wide variety of portable electronics, ranging from calculators to small toys to lighted key chains. Premium based on many years of experience and know-how in the field of silver oxide batteries, the LR battery boasts high quality and high reliability.
The button-type alkaline battery uses manganese dioxide (MnO2) as its positive active material and zinc (Zn) as its negative active material. Potassium hydroxide (KOH) is used as an electrolyte.
