Cotchear, a professional battery product manufacturer founded in 1995, is our mission to provide high-quality products with ultra-high cost-effectiveness. As a professional international battery product manufacturer, each battery has undergone professional testing and meets the highest safety standards.

The AG4 / LR626 battery, with a metal construction and a zinc/manganese dioxide chemistry, delivers a standard voltage of 1.55V and a short circuit current of 0.3A. Designed for storage and operation at temperatures below 45°C, this button battery measures approximately 6.8mm in diameter and 2.6mm in thickness.

Featuring a high capacity of 20mAh and durable performance, the AG4 / LR626 battery utilizes chip upgrades for stable and consistent discharge. Its unique U-shaped sealed steel shell structure effectively prevents liquid leakage, while the nickel-plated stainless steel outer layer provides strong sealing, short circuit protection, and anti-leakage properties.

The use of stable manganese dioxide as the positive electrode material and high-quality zinc metal for the negative electrode ensures a stable voltage output, effectively protecting electronic equipment. Furthermore, the battery is mercury-free, making it a healthy and environmentally friendly choice.

It is important to note that the AG4 / LR626 battery should be kept away from fire and not recharged. Additionally, it should be stored in a dark, cool, and dry place, and kept out of reach of children, as swallowing the battery could cause choking and other bodily injuries.

To ensure optimal performance and safety, it is recommended to avoid stacking the batteries together, as this can lead to short circuits and affect the battery's lifespan. When inserting the battery, users should ensure the correct orientation to avoid short-circuits.
