SAFT LS 14250
The SAFT LS 14250 is a 3.6 V primary lithium battery in 1/2 AA size. It is used where a stable power supply is needed over a very long period, and where the battery typically does not need to be recharged or replaced often. The battery is based on lithium-thionyl chloride chemistry and is constructed as a bobbin cell, which is known for being well-suited for low currents over a long service life.
The capacity is 1.2 Ah at less than 1 mA, +20 °C, and with a 2.0 V cut-off. In practice, this means the cell is well-suited for equipment with low and steady consumption. The open-circuit voltage is around 3.67 V, making it relevant for applications that require a high nominal voltage in a compact cell.
The construction is hermetically sealed with a glass-to-metal seal and a stainless steel casing. Furthermore, the electrolyte is non-flammable. These are features that are particularly valuable in professional equipment where operational reliability and long service life are highly prioritized.
The cell can be used in a wide temperature range from -60°C to +85°C. The recommended continuous current is up to 35 mA, and it can handle pulses up to 100 mA. This makes it suitable for equipment that normally runs on low consumption but occasionally draws a short current spike.
It is designed for long-term applications with a typical lifespan of 5 to 20+ years and complies with, among others, UL 1642, IEC 60086-4, and UN transport regulations. The manufacturer's datasheet can be viewed here: See manufacturer's datasheet
Typical applications
The LS 14250 is typically used in equipment where the battery must last for many years and where there is no need for high continuous current. This can be in measuring equipment, electronics with memory backup, sensors, and other industrial or automation setups with low power consumption.
