Principle and reaction

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.

　


Features

●Excellent cost-performance
Unlike silver oxide batteries that use the precious metal, silver, the alkaline battery features good cost-performance because it uses low-cost manganese dioxide as its active material.


●Superior leakage* resistance
Like silver oxide batteries, the LR battery is manufactured using the Maxell s original leak-resistant processing that suppresses the electrolyte from rising up and seeping out ¡X a basic 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.
(* Leakage is defined as an unintended escape of liquid from a battery.)

　


Applications

Mini-game machines, electronic calculators, electronic clocks, electronic watches, measuring instruments, electronic lighters, electronic thermometers, cameras, compact radios, and various types of remote controllers, etc.
