Why choose it

The LS26500's bobbin construction and high-purity lithium anode enable exceptionally low self-discharge, ensuring that devices remain powered for over a decade in standby mode. Its wide operating temperature range allows deployment in harsh environments, from Arctic cold to desert heat, without performance degradation. The stable voltage plateau of Li-SOCl2 chemistry means your electronics receive consistent power until the very end of battery life, preventing data loss or erratic readings.

Ideal use cases

• Smart utility meters (electricity, gas, water)
• GPS tracking devices and asset trackers
• Wireless sensors and IoT endpoints
• Remote monitoring and data loggers
• Alarm systems and security devices
• Medical devices requiring long-term power

Good to know

The LS26500 is a primary (non-rechargeable) cell and must not be recharged. It should be stored in a cool, dry place and protected from short circuits. For applications requiring high pulse currents, consider pairing with a capacitor or using Saft's hybrid cells. Always follow local regulations for battery disposal.
