LRN04N

Updated: 2026-07-19

Overview

The LRN04N is a type of lithium thionyl chloride (Li-SOCl2) battery, known for its high energy density and extended operational life. These batteries are widely used in applications requiring long-term, reliable power with minimal maintenance. Lithium thionyl chloride batteries operate via a non-rechargeable electrochemical reaction between lithium and thionyl chloride, producing a stable voltage output. The LRN04N variant is particularly favored for its compact size and robustness in harsh environments.

Physical and Chemical Properties

The LRN04N battery features a cylindrical design with a metal casing, ensuring durability and protection for the internal components. The electrolyte consists of thionyl chloride (SOCl2), which reacts with the lithium anode to generate electricity. Key physical properties include a wide operating temperature range (-55°C to +85°C) and low self-discharge rates, making it suitable for extreme conditions. The chemical stability of the electrolyte contributes to the battery's long shelf life, often exceeding 10 years when stored properly.

B2B Procurement Guide

When sourcing LRN04N batteries, prioritize suppliers with certifications such as ISO 9001 or UL listing to ensure quality and compliance. Verify the battery's specifications match your application requirements, including voltage, capacity, and temperature tolerance. Bulk purchases often reduce costs, but ensure proper storage conditions are maintained. Request samples for testing before large-scale procurement to confirm performance and compatibility.
