  • 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 — a basic phenomenon of alkaline electrolytes.

* Leakage is defined as an unintended escape of liquid from a battery.

 

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.
