Saft Lithium round cell LSH14 LF-U with 3.6 V and 5.8 Ah

The Saft LSH14 LF-U is a high-performance lithium thionyl chloride battery (Li-SOCl2) in size C, which is assembled with U-shaped solder connections for flexible and robust mounting. It combines the spiral-shaped high-performance technology of the LSH series with versatile connection options. With a rated voltage of 3.6 V and a capacity of 5.8 Ah, it is the ideal choice for demanding devices that require high energy output and flexible installation.

Highlights at a glance

• Flexible mounting: U-shaped solder terminals (LF-U) for versatile installation positions
• High current carrying capacity: Developed for high continuous currents up to 1300 mA
• High capacity: 5.8 Ah for a long-lasting and powerful energy supply
• High pulse capacity: Reliable output of pulses up to 2500 mA
• Spiral technology: Optimised for fast energy output with minimal voltage drop
• Robust: Hermetically sealed stainless steel housing for maximum operational safety

Maximum power for demanding applications

The Saft LSH14 LF-U was designed for use in professional devices that require high performance and a wired connection. The U-shaped solder connections enable a secure connection using cables. Typical applications include emergency transmitters (ELT, EPIRB), military equipment, professional power tools and industrial applications where the power source cannot be placed directly on the circuit board.

Superior spiral technology for high currents

In contrast to batteries with a wound design (bobbin type), the spiral design of the LSH14 maximises the active electrode surface. This enables a significantly faster chemical reaction and therefore the delivery of much higher currents with stable voltage behaviour. This ensures reliable and constant performance of your application even under high load.

Efficiency and guaranteed safety

The cell is hermetically sealed with a glass-to-metal seal to minimise the risk of current leakage and has a non-flammable electrolyte, which significantly increases operational safety. The LSH14 LF-U complies with the IEC 60086-4 safety standard and is UL certified, making it suitable for safety-critical applications with high power requirements.

FAQs about the Saft LSH14 LF-U lithium round cell

What does the designation LF-U mean?

The LF-U labelling describes the type of connections on the battery. "LF" stands for solder connection and the "U" specifies their shape as U-shaped solder lugs. These allow cables to be soldered on or used in certain holders, which offers a high degree of flexibility during installation.

What is the main difference to the Saft LS26500?

Although both batteries are size C, they are optimised for different purposes. The LSH14 LF-U is designed for high power and high current output thanks to its spiral technology. The LS26500 is optimised for an extremely long service life with very low power consumption.

For which applications is this version with solder connections suitable?

This version is ideal for high-performance 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 source.

Does the LSH14 have a higher self-discharge rate than an LS battery?

Yes, due to the spiral design with a larger electrode surface, the self-discharge of the LSH series tends to be slightly higher than that of the LS series. Nevertheless, it offers excellent shelf life and durability for a high-performance battery.

Is the LSH14 LF-U rechargeable?

No, the LSH14 LF-U is a lithium primary battery and must not be recharged under any circumstances. Any attempt to charge it is dangerous and can lead to the destruction of the cell or to a deflagration.
