Introduction

The LR41 / AG3 is a 1.5V alkaline manganese dioxide button cell engineered for compact medical and electronic devices. Using a high-purity zinc anode, MnO₂ cathode, and KOH electrolyte, it ensures stable voltage, low internal resistance, and leak-proof reliability.
With 32–38mAh capacity and excellent pulse discharge, it delivers consistent performance in thermometers, watches, and laser pointers. Compared with SR41 silver oxide cells, it offers a more economical, mercury-free solution; and versus lithium coin cells, it suits low-voltage precision circuits. Certified ROHS, CE, MSDS, the LR41 combines energy efficiency, durability, and environmental safety.
