ER26500H C 3.6V

ER26500H C 3.6V Lithium Thionyl Chloride Battery – High Capacity, Bobbin-type, Ultra-Low Self-Discharge, Long-Term Reliability.

Product Overview

The ER26500H is a high-capacity, bobbin-type, C-size 3.6V lithium thionyl chloride (Li-SOCl2) battery, meticulously designed for low-drain, long-duration applications.


ER26500H offers a stable voltage of 3.6 V and an impressive energy density of 700 Wh/kg, enabling product miniaturization and extending operational life. These durable cells demonstrate an exceptionally low annual self-discharge rate of ≤ 1% per year, achieved through the use of high-quality raw materials and proprietary construction techniques that utilize the passivation effect.


With a nominal capacity of 8,500 mAh and an impressive energy density of up to 700 Wh/kg, this non-rechargeable lithium battery provides stable voltage and exceptional shelf life, making it ideal for devices that require reliable, long-term performance.


Designed to endure extreme environmental conditions, the ER26500H operates reliably across the industry's widest temperature range, from -55°C to +85°C. Its hermetically sealed construction provides superior leak prevention compared to crimped seals, making it ideal for critical applications such as utility metering, environmental monitoring, and various industrial IoT devices.
