Alkaline Button Batteries

Product details

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.

  • Features

    • Excellent cost-performance. Unlike silver oxide batteries that use the precious metal, silver, alkaline batteries feature good cost-performance because they use low-cost manganese dioxide as its active material.
    • Superior leakage resistance. Like silver oxide batteries, the LR battery is manufactured using Maxell's original leak-resistant processing that suppresses the electrolyte from rising up and seeping out — a common phenomenon of alkaline electrolytes.
    • Excellent heavy load characteristics. The LR battery offers excellent heavy load characteristics and employs a separator featuring low internal resistance, good liquid holding properties and high-drain characteristics.

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.
