Saft LS14250 3.6V 1/2 AA Lithium Battery

When a device needs to run reliably for years without a battery change, the Saft LS14250 is the battery engineers and technicians reach for. This 3.6V 1/2 AA lithium cell is built around lithium thionyl chloride (Li-SOCl2) chemistry, which delivers more energy per ounce than virtually any other primary battery type available. Whether you're replacing a battery in a security system, a utility meter, or a memory backup application, the LS14250 is a trusted solution.

Built for the Long Haul

One of the standout qualities of the LS14250 is its exceptional shelf life. Thanks to an extremely low self-discharge rate of less than 1% per year, this battery holds its charge for up to 10 years in storage. That means devices can sit dormant for extended periods and still power up reliably when needed. It's the kind of dependability that makes the LS14250 the go-to choice for installations where swapping batteries isn't easy or practical.

Stable Voltage. Extreme Conditions. No Problem.

The LS14250 maintains a steady 3.6V output throughout most of its discharge cycle. That flat, stable voltage curve is important for devices that rely on consistent power to function accurately, like meters and data loggers. The battery also performs in temperatures ranging from -76°F all the way up to 185°F, making it suitable for outdoor installations, industrial environments, and applications exposed to harsh weather.

Compact Size, Serious Capacity

The 1/2 AA form factor measures just 0.57 inches in diameter and about 1 inch in length, but packs 1,200 mAh of capacity into that small footprint. The bobbin-style construction maximizes the amount of active material inside the cell, which translates directly to higher energy density and longer run times. At only 0.3 oz, it's a lightweight option that fits into tight spaces without sacrificing performance.

Where the LS14250 Gets the Job Done

This battery is designed for low-drain, long-life applications where reliability is non-negotiable. Common uses include:

• Security systems and alarm transmitters
• Utility and automatic meter reading devices
• Computer and PLC memory backup
• Real-time clocks and data loggers
• Tracking and telemetry systems
• Invisible fence and pet containment systems
• Wireless sensors and remote monitoring equipment

It's also a widely used replacement for PRAM batteries in older Apple computers, dive computer batteries from brands like Suunto and Aladin, and a variety of industrial control systems.

A Reliable Name Behind the Battery

Saft is one of the most respected names in primary lithium battery manufacturing, with a long track record supplying cells for industrial, military, and mission-critical applications around the world. The LS14250 is made to Saft's rigorous quality standards and meets IEC 60086-4 safety requirements. The stainless steel housing with hermetic glass-to-metal sealing protects the cell against moisture and corrosion, even in demanding environments.
