Key Features
1. High Energy Capacity — 19,000mAh
The ER34615 provides up to 19Ah nominal capacity in a compact D-size cylindrical format, making it suitable for long-life industrial and IoT applications.
2. Stable 3.6V Operating Voltage
The Li-SOCl₂ chemistry provides a high and stable nominal voltage, helping reduce the number of cells required in many low-power electronic systems.
3. Extremely Low Self-Discharge
The battery can achieve a self-discharge rate of less than 1% per year under suitable storage conditions, supporting long-term standby applications.
4. Wide Operating Temperature Range
Designed for demanding environments, ER34615 cells are commonly specified for operation from -55°C to +85°C. Actual performance and available capacity may vary with temperature and discharge rate.
5. High Energy Density
The Li-SOCl₂ system offers high energy density and long operating life, making it well suited to devices where battery replacement is difficult or costly.
6. Long Shelf Life
With very low annual self-discharge, ER34615 batteries can provide a shelf life of 10 years or more when stored under appropriate conditions.
7. Hermetically Sealed Construction
The cylindrical cell can use a stainless-steel case with hermetic glass-to-metal sealing, helping protect the internal chemistry in demanding industrial environments.
8. Non-Rechargeable Primary Cell
ER34615 is a primary lithium battery and is not designed for recharging. It should be used with an appropriate load and battery management/protection design.
