The ER26500 battery is a primary lithium battery. This means that it cannot be recharged. It uses lithium thionyl chloride (Li-SOCl₂) as its chemical composition and has a cylindrical shape. This battery operates at a voltage of 3.6V. The name "ER26500" refers to its size, which has a diameter of 26.2 mm and a height of 50.5 mm. It is classified as a size 'C' battery. The ER26500 size C 3.6 V batteries are ideal for devices that operate at higher voltage. The strong voltage and good discharge characteristics make them a top choice for many purposes. These batteries are designed for devices that require continuous, stable power, such as water meters, GPS trackers, industrial sensors, and security systems.
