Saft Lithium round cell LS26500 with 3.6 V and 7.7 Ah

The Saft LS26500 is a high-performance lithium thionyl chloride battery (Li-SOCl2) in size C, developed for demanding industrial applications with very high energy requirements. It offers a nominal voltage of 3.6 V and an exceptionally high capacity of 7.7 Ah. Thanks to its extremely low self-discharge and robust construction, it is the ideal choice for long-life applications where maximum reliability and a long, maintenance-free operating life are required.

Highlights at a glance

• Very high capacity: 7.7 Ah in the C size for maximum runtime
• Powerful: High and stable operating voltage of 3.6 V
• Extremely long-lasting: Very low self-discharge of under 1% per year
• Reliable: Excellent response behaviour even after long storage
• Robust: Hermetically sealed stainless steel case for maximum operational safety
• Versatile: Usable in a wide temperature range from -60 °C to +85 °C

Powerful for energy-intensive applications

The Saft LS26500 is the perfect energy solution for professional and industrial devices that require a high amount of energy over a long period. Its high capacity makes it the first choice for meters for gas, water or electricity (metering), memory backup systems (memory back up), buoys, tracking systems as well as industrial controls. Thanks to its ability to deliver stable performance even at low temperatures, it ensures the functionality of your devices under all conditions.

Efficiency and guaranteed safety

The proven lithium thionyl chloride technology guarantees reliable energy output over many years. The cell is hermetically sealed by a glass-to-metal seal to minimise the risk of leakage, and features a non-flammable electrolyte which significantly increases operational safety. The LS26500 complies with safety standard IEC 60086-4 as well as being UL certified and thus demonstrates its suitability for safety-critical applications.

Robust Li-SOCl2 technology for industry

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 right up to the end of the discharge cycle, even after long periods of storage. The robust construction protects the cell reliably against corrosion and environmental influences, ensuring the functionality of your application over the entire product lifetime.
 

Characteristics

FAQs about the Saft LS26500 lithium round cell

What does the size C mean?

The C size describes a cell that has the same height as a standard AA battery but has a larger diameter (approx. 26 mm compared to 14.5 mm). This larger diameter allows a significantly higher capacity.

Is the Saft LS26500 rechargeable?

No, the LS26500 is a lithium primary battery and must never be recharged under any circumstances. Any attempt to charge is dangerous and can lead to cell destruction, leakage, or bursting.

For which applications is the LS26500 particularly suitable?

It is optimal for professional applications with high energy requirements and low continuous current that must operate autonomously for many years. These include in particular meters (smart metering), long-term data loggers, maritime buoys and demanding security technology.

What is the difference to the Saft LS17500?

Both cells have the same height, but the LS26500 (size C) is thicker than the LS17500 (size A). Due to the larger volume, the LS26500, with 7.7 Ah, offers a much higher capacity than the LS17500, with 3.6 Ah, and enables longer runtimes.

How must the LS26500 be correctly disposed of?

As a lithium battery, it is subject to special disposal regulations. It must be handed in to the relevant municipal collection points or specialist dealers. Disposal with household waste is not permitted.
