Saft Lithium round cell LS26500PLUS with 3.6 V and 8.5 Ah

The Saft LS26500PLUS is a highly specialised lithium thionyl chloride battery (Li-SOCl2) of the C-class, developed specifically for demanding applications with high pulse current requirements. It combines a very high nominal voltage of 3.6 V and an exceptional capacity of 8.5 Ah with the ability to reliably deliver high current pulses. This makes it the ideal energy source for long-life applications that require periodic high peak loads in addition to a low base current.

Highlights at a glance

• Optimised for pulse loads: Ideal for applications with high peak current requirements, such as radio modules
• Very high capacity: 8.5 Ah for maximum runtime and energy density
• High pulse capability: Reliable delivery of high current pulses (up to 2 A)
• Minimal voltage drop: Low voltage drop even with high loads
• Extremely long-lasting: Low self-discharge for a long shelf life and operating time
• Robust: Hermetically sealed stainless steel housing for maximum operational safety

Powerful for modern wireless and tracking applications

The Saft LS26500PLUS was specifically developed for use in professional devices that use transmission pulses for data transfer. It is ideally suited for smart metering (electricity, gas, water meters with radio module), asset tracking, industrial IoT sensors, alarm systems and other applications that require long autonomous operating times along with high peak current needs.

Optimised technology for pulse applications

The proven lithium thionyl chloride technology of the PLUS series has been specially developed for the requirements of modern electronics. The internal construction of the cell minimises the voltage drop during high current pulses (passivation effect), ensuring stable and reliable device operation throughout the entire lifecycle. This guarantees maximum efficiency and data transmission security.

Efficiency and guaranteed safety

The cell is hermetically sealed with a glass-to-metal seal to minimise the risk of current leakage and contains a non-flammable electrolyte. This significantly increases operational safety. The LS26500PLUS meets the IEC 60086-4 safety standard and is UL certified, making it suitable for safety-critical applications.

FAQs about the Saft LS26500PLUS lithium round cell

What does the "PLUS" designation mean for this battery?

The "PLUS" designation indicates the special suitability of this Saft battery series for applications with high pulse current requirements. Compared to the standard series, the PLUS series can supply significantly higher currents for short periods, which is essential for devices with radio or transmission modules.

What is the difference from the standard Saft LS26500?

The LS26500PLUS offers a higher capacity of 8.5 Ah than the standard LS26500 (7.7 Ah). However, the key difference is its optimised ability to handle high current pulses with a lower voltage drop, ensuring reliability in wireless applications.

For which devices is the LS26500PLUS particularly suitable?

It is optimal for all professional devices that operate at low current for long periods of time but periodically require high currents to transmit data. Examples include smart meters, GPS trackers, industrial wireless sensors and security systems with transmission module.

Is the LS26500PLUS rechargeable?

No, this is a lithium primary battery, which is not rechargeable. Any attempt to charge the battery is dangerous and may result in cell destruction, leakage or explosion.

How should the LS26500PLUS be disposed of correctly?

As a lithium battery, it is subject to special disposal regulations. It must be taken to appropriate municipal collection points or specialist retailers. Disposal via household waste is not permitted.
