ER17335H 2/3A 3.6V

2/3A-size 3.6V Lithium Battery – High Capacity, Bobbin-Structure, Ultra-Low Self-Discharge, Extended Operating Life.

Product Overview

ER17335H 2/3A 3.6V

The ER17335H is a high-capacity, 2/3A-size 3.6V lithium thionyl chloride (Li-SOCl₂) battery designed with bobbin-type construction, making it an ideal choice for long-term, low-drain applications.


With a nominal capacity of 1900mAh and an impressive energy density of up to 700Wh/kg, this non-rechargeable battery delivers exceptionally stable performance, long shelf life, and outstanding reliability in harsh environments. It is widely used in smart meters, industrial automation, medical devices, and IoT systems that demand long-lasting power.


Engineered for extreme conditions, the ER17335H provides a stable output voltage with an ultra-low self-discharge rate (less than 1% per year at 25°C), ensuring a shelf life of over 10 years under optimal storage. 


Its advanced lithium metal anode and carbon-thionyl chloride cathode enable consistent performance during continuous and pulse discharge. Certified to UN38.3, UL, and CE standards, this primary lithium battery is globally recognized for its safety and reliability.


All SUNJ batteries are designed to withstand reasonably foreseeable misuse and are tested in compliance with international performance, safety, and transport regulations.
