The ER series includes various sizes and capacities, catering to a wide range of needs. The key characteristics that define these batteries are their high operating voltage, wide temperature range, independence from cell orientation, superior shelf life, and reliability, and their spiral structure, which is ideal for high current discharge applications.
2. High Operating Voltage and Stability
One of the most notable features of the ER series batteries is their high operating voltage of 3.6V. This voltage remains stable throughout most of the application lifetime, ensuring consistent performance and reliability. The stability of the operating voltage is crucial in applications where precise power delivery is essential. For instance, in medical devices, electronic locks, and security systems, a consistent power supply is vital for optimal performance.
The stability of the operating voltage is achieved through the use of the Li-SOCL₂ electrolyte.

This is in contrast to some other battery chemistries, which may experience a significant voltage drop as they approach the end of their discharge cycle.
3. Wide Temperature Range
Another key advantage of the ER series batteries is their wide temperature range, which spans from -55°C to +85°C. This makes them suitable for use in extreme environments where traditional batteries may fail to perform. For example, in military and aerospace applications, where equipment may be exposed to harsh conditions, the ability to operate reliably across a wide temperature range is crucial.
The wide temperature range of the ER series batteries is achieved through the use of advanced materials and design techniques. The electrolyte and anode materials are specifically chosen to maintain performance over a broad temperature spectrum. Additionally, the battery's spiral structure helps to distribute heat evenly, preventing localized overheating and ensuring consistent performance.
4. Performance Independent from Cell Orientation
Unlike some other battery types, the performance of the ER series batteries is independent of cell orientation. This means that the batteries can be used in any orientation without affecting their performance. This is particularly beneficial in applications where space is limited, and the battery may need to be positioned in a non-standard way.
The independence from cell orientation is achieved through the use of a spiral wound electrode design. In this design, the anode, cathode, and separator are wound together into a spiral shape. This configuration ensures that the battery's internal resistance remains consistent regardless of its orientation, allowing for consistent performance in any position.
5. Superior Shelf Life and Reliability
The ER series batteries offer superior shelf life and reliability, with a shelf life of over 10 years at room temperature. This is significantly longer than many other primary battery types, making them ideal for applications where long-term storage is required. Additionally, the self-discharge rate of these batteries is less than 1% per year, ensuring that they retain their charge over extended periods.
The superior shelf life and reliability of the ER series batteries are achieved through the use of high-quality materials and precision manufacturing techniques. The electrolyte and electrode materials are carefully selected to minimize chemical degradation over time. Additionally, the battery's spiral wound design helps to prevent internal shorts and leaks, further enhancing its reliability.
6. Spiral Structure and High Current Discharge Capability
The spiral structure of the ER series batteries is not only beneficial for their independence from cell orientation but also for their high current discharge capability. The spiral wound design allows for efficient ion transport and electron flow, enabling the batteries to deliver high currents without significant voltage drop.
This high current discharge capability is crucial in applications such as power tools, emergency lighting, and remote-controlled vehicles. In these applications, the ability to deliver a high burst of power quickly is essential for optimal performance. The spiral structure of the ER series batteries allows them to meet these demands, making them an excellent choice for high-power applications.
It is worth noting that some ER series batteries may require activation before they can deliver medium currents. This activation process typically involves applying a small initial load to the battery, which primes the electrolyte and electrode materials for optimal performance. Once activated, the batteries can deliver consistent high currents over their entire discharge cycle.
