Saft Lithium battery LSH 20 3.6V 13Ah with axial drainers

The Saft LSH 20 is a high-performance 3.6-volt lithium primary battery in size D (mono), which was developed for professional and industrial applications with high energy and power requirements. Based on lithium thionyl chloride technology (Li-SOCl2), it is specially optimised for applications that require both a long service life and the ability to deliver high current pulses. This variant is pre-configured with axial wire leads for direct and secure PCB mounting.

Highlights at a glance

• High current load capability: Developed for applications with high continuous and peak current requirements (high drain).
• Maximum capacity and energy density: With 13 Ah, an extremely energy-rich battery for long, self-sufficient operating times.
• Extreme longevity: Low self-discharge provides a shelf and service life of over 10 years.
• Extremely wide temperature range: Reliable performance under the most extreme conditions from -60 °C to +85 °C.
• Industrial configuration: Equipped with robust, axial wire leads for easy and secure PCB mounting.

Reliable energy for critical high-current applications

The Saft LSH 20 is the preferred energy source for demanding applications where a long service life and high pulse currents are required. Its main field of application is powering radio modules (e.g., in remote meter reading), GPS tracking systems (asset tracking), oceanography, military uses, and security technology. It is the ideal solution when devices remain dormant for years but must deliver high power immediately when required.

Superior lithium thionyl chloride technology

The lithium thionyl chloride technology (Li-SOCl2) of the LSH series is designed for high performance. It offers the highest energy density of all primary lithium chemistries and a very stable voltage during discharge, even at high loads. The cells are hermetically sealed and distinguished by maximum safety and reliability, making them the first choice for critical and hard-to-reach applications.

Developed for industrial integration

As an industrially pre-configured cell, the LSH 20 with axial wire leads is optimised for efficient and process-secure manual or automated PCB assembly. The robust connecting wires ensure a permanently secure and vibration-resistant solder connection. With this cell, Saft offers developers and manufacturers a reliable and extremely powerful platform for designing durable and low-maintenance products.
 

Characteristics

FAQs about the Saft LSH 20 lithium battery

What is the difference between the LSH and LS series from Saft?

Both series are based on Li-SOCl2 technology. The LSH series (high drain, e.g., LSH 20) is optimised for applications with high current requirements (high pulse and continuous currents). The LS series (low drain, e.g., LS 33600) is designed for applications with very low continuous current over an extremely long period (up to 20 years), such as pure backup buffering.

What does "axial leads" mean?

Axial leads are connecting wires that are routed centrally from the two flat ends (terminals) of the cylindrical cell, i.e., along the longitudinal axis of the battery. This configuration is ideal for horizontal mounting and threading the wires through holes in a printed circuit board (through-hole technology, THT).

Is this battery rechargeable?

No, under no circumstances. This is a lithium primary battery. It must not be attempted to recharge it under any circumstances. Attempts to charge are extremely dangerous and can lead to fire or explosion of the cell.

How should this battery be disposed of?

Batteries must not be disposed of with household waste. As an industrial battery, it is subject to the provisions of the Battery Act. Please hand in the empty battery to the designated industrial or municipal take-back points to ensure proper and environmentally sound recycling.
