What is the ER26500 Li-SOCl₂ Battery?
The ER26500 is a cylindrical 3.6V lithium thionyl chloride battery that comes in a C-size form factor. Renowned for its high energy density, exceptional shelf life, and stable output, this battery is built for applications that require reliable, long-term performance, especially in environments with extreme temperatures.

Top Features of the ER26500 9000mAh Battery
1. High Capacity – 9000mAh
One of the most important features of the ER26500 battery is its impressive 9000mAh capacity, which ensures extended operational time for devices. This makes it suitable for equipment that must run for months or years without being serviced, such as:
- Utility meters (gas, water, electricity)
- IoT sensors and devices
- GPS tracking systems
- Medical and safety equipment

With this high capacity, the battery can deliver consistent performance over several years, minimizing downtime and maintenance.
2. Chemistry: Lithium Thionyl Chloride (Li-SOCl₂)
The use of Li-SOCl₂ chemistry brings several advantages:
- Extremely high energy density (up to 650 Wh/kg)
- Stable voltage output around 3.6V throughout most of its discharge cycle
- Low self-discharge rate—typically less than 1% per year
- Long storage life of up to 10 years
This chemistry is ideal for mission-critical applications where replacement access is difficult, and battery failure is not an option.
3. Wide Operating Temperature Range
The ER26500 battery is engineered to operate in extreme conditions, with a temperature range of approximately:
- –55°C to +85°C
This feature makes it highly suitable for Saudi Arabia’s diverse environments, from desert heat to cold storage facilities. It’s especially useful in:
- Remote oil and gas installations
- Industrial control systems
- Outdoor surveillance units
4. Stable Voltage Output
Maintaining a steady 3.6V output during most of its discharge cycle is crucial for devices that rely on constant voltage to function optimally. The ER26500 excels in this area, ensuring electronics such as sensors and data loggers receive uninterrupted power without voltage drops that could corrupt readings or data.
5. Low Self-Discharge Rate
Thanks to its chemical composition and superior sealing, the ER26500 battery loses less than 1% of its capacity annually under room temperature storage conditions. This allows:
- Long shelf life before installation
- Reduced total cost of ownership
- Ideal for infrequent-use or standby applications
6. Superior Safety and Durability
Built with high-quality stainless steel casing and hermetic sealing, the ER26500 ensures:
- Leak-proof performance
- Resistance to corrosion
- No risk of swelling or thermal runaway
These features are essential for industrial reliability, especially in the petrochemical and defense industries where safety is paramount.
7. Compatibility with Industrial Applications
The ER26500 battery is compatible with a broad spectrum of devices, including:
- Data loggers and RFID devices
- Gas and water meters
- Remote sensors and wireless modules
- Tracking and telematics systems
ASKA Solution offers certified ER26500 batteries that meet industrial requirements in Saudi Arabia for safety, durability, and performance.
