LS14250 Button Cell

Updated: 2026-11-07

Overview

The LS14250 is a cylindrical lithium thionyl chloride (Li-SOCl2) battery, known for its high energy density and long operational life. It is commonly used in applications requiring reliable, long-term power with minimal maintenance. Due to its stable voltage output, it is favored in critical systems like medical implants and military hardware. The battery operates under harsh environmental conditions, making it suitable for remote sensors and emergency equipment. Its non-rechargeable design ensures consistent performance until depletion, with a shelf life of up to 10 years under optimal storage conditions.

Physical and Chemical Properties

The LS14250 battery features a nominal voltage of 3.6V and a typical capacity of 1.2Ah. Its lithium thionyl chloride chemistry provides a high energy density, outperforming alkaline and other lithium-based batteries in energy-to-weight ratio. The electrolyte consists of thionyl chloride (SOCl2), which acts as both the electrolyte and cathode material. The battery's metal casing ensures durability and resistance to leakage. Due to its chemistry, it is stable across a wide temperature range (-40°C to +85°C), making it ideal for extreme environments. However, improper handling can lead to hazardous reactions, necessitating strict safety protocols during use and disposal.

Main Applications

LS14250 batteries are widely used in medical devices, such as implantable neurostimulators and diagnostic tools, where reliability is critical. Their long shelf life and stable discharge curve make them indispensable in these applications. In industrial settings, they power remote sensors, metering systems, and automated equipment. Military and aerospace sectors utilize them for communication devices and emergency locators due to their resilience. Their niche in IoT devices is growing, particularly for low-power, long-duration deployments.

Safety and Storage

Proper storage of LS14250 batteries involves keeping them in a dry environment at room temperature (15°C–25°C). Exposure to moisture or high temperatures can degrade performance or cause leaks. Avoid stacking batteries to prevent physical damage or short circuits. Safety precautions include using insulated tools during installation and avoiding mechanical stress. Disposal must comply with local regulations for lithium batteries due to their reactive components. Incineration or crushing can lead to hazardous chemical releases.

B2B Procurement Guide

When procuring LS14250 batteries, verify supplier credentials, such as ISO 9001 certification, to ensure quality consistency. Bulk purchases often yield cost savings, but confirm batch testing reports for performance reliability. Key procurement considerations include compatibility with end-use devices, lead times, and warranties. For specialized applications (e.g., medical or military), suppliers must provide documentation meeting industry standards. Regional shipping regulations for lithium batteries may affect logistics.
