Additional Note: The MR43 is a Mercuric-Oxide cell of the same dimensions as the A186/LR43. The MR43 cells are no longer manufactured because of their toxicity. If your requirement is to replace an MR43, you may consider using the Alkaline A186/LR43 in its place.

Technical Specifications: Maxell Alkaline Batteries [Button Cell]

The Maxell LR 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 & thermometers; to small toys & lighted key chains.  Maxell's 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 of Maxell Alkaline Button Cell Batteries:

  • 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.

Positive reaction:  MnO2 + H+ +e-  MnOOH
Negative reaction:    Zn + 2OH-  ZnO + H2O + 2e-
Total reaction:  2MnO2 + H2O + Zn  2MnOOH + ZnO
