Saft Lithium round cell LS14500 LF-U with 3.6 V and 2.6 Ah

The Saft LS14500 LF-U is a high-performance lithium thionyl chloride battery (Li-SOCl2) in AA size, which is assembled with U-shaped solder tags for flexible and robust mounting. This special version is based on the powerful LS14500 cell and offers a nominal voltage of 3.6 V as well as a high capacity of 2.6 Ah. Thanks to its extremely low self-discharge and high reliability, it is the ideal energy source for long-lasting industrial electronics.

Highlights at a glance

• Flexible mounting: U-shaped solder tags (LF-U) for versatile installation positions
• High capacity: 2.6 Ah in the standard AA size for maximum energy density
• Powerful: High and stable operating voltage of 3.6 V
• Extremely long-lasting: Very low self-discharge of less than 1% per year
• Robust: Hermetically sealed stainless steel housing for maximum operational safety
• Versatile: Can be used in a wide temperature range from -60°C to +85°C

Powerful for versatile industrial applications

The Saft LS14500 LF-U was designed for use in professional devices where the battery is not soldered directly onto a circuit board but requires a flexible connection. The U-shaped solder tags enable a secure connection by means of cables or in special battery holders. Typical areas of application include memory backup systems, alarm systems, medical devices, counters and industrial control units that require a reliable and long-lasting power supply.

Efficiency and guaranteed safety

The proven lithium thionyl chloride technology guarantees reliable energy output for many years. The cell is hermetically sealed by means of a glass-to-metal seal to minimise the risk of leakage current, and it has a non-flammable electrolyte, which significantly increases operational safety. The LS14500 LF-U complies with the IEC 60086-4 safety standard and is UL certified.

Robust Li-SOCl2 technology for professionals

Lithium thionyl chloride chemistry stands for superior energy density and an exceptionally long service life. Compared to other battery technologies, it offers a stable voltage level right to the end of the discharge cycle. The robust construction reliably protects the cell against corrosion and mechanical stress, thus ensuring the functionality of your application throughout the entire product service life.
 

Characteristics

FAQs about the Saft LS14500 LF-U lithium round cell

What does the designation LF-U mean?

The designation LF-U describes the type of connections of the battery. "LF" stands for solder tag and the "U" specifies their shape as U-shaped solder tags. These allow cables to be soldered or used in certain holders, providing a high degree of flexibility during installation.

Is the Saft LS14500 LF-U rechargeable?

No, the LS14500 LF-U is a lithium primary battery and must never be recharged under any circumstances. Any attempt at charging is dangerous, damages the cell and can lead to leakage or deflagration.

What is the difference compared to versions with pins (e.g. 2PF)?

While versions with pins (PF) are designed for direct mounting in suitable holes on a circuit board, the U-shaped solder tags (LF-U) offer more flexibility. Cables of different lengths can be soldered to them to position the battery freely in the device housing.

Can this battery be used in normal devices for AA batteries?

No, this battery is exclusively intended for professional electronics with an operating voltage of 3.6 V per cell. The voltage is more than twice that of a conventional 1.5 V AA battery.

For which applications is this version with solder tags suitable?

This version is ideal for applications where the battery is not mounted directly on a circuit board. It is often used to replace older batteries with soldered cables or in devices that require a flexible, wired connection to the power supply.
