1. Low self-discharge rate:

The core of this battery pack lies in its use of lithium-thionyl chloride (Li-SOCl2) chemistry. Li-SOCl2 batteries are known for their high specific energy, which translates into longer operating times for devices powered by them. This chemistry also exhibits a low self-discharge rate, ensuring that the battery retains its charge for extended periods, even when not in use. The Er18505 SPC1520 model, specifically, offers a compact size with a high capacity, making it suitable for use in space-constrained environments.

2. High discharge current, especialy for pulse discharge current:

The addition of the EPC1520 capacitor to this battery pack further enhances its performance. Capacitors are known for their ability to store and release energy quickly, providing a burst of power when needed. By combining the steady power supply of the Li-SOCl2 battery with the instantaneous power delivery of the capacitor, the battery pack is able to meet the demands of high-drain applications while maintaining stable performance.

3. Long storage life, No voltage delay and passivation.

One of the key advantages of the 3.6V Er18505 SPC1520 Primary Li-SOCl2 Battery ER18505H Plus EPC1520 Capacitor Battery Pack is its excellent shelf life. Li-SOCl2 batteries are renowned for their long-term stability, and this particular model is designed to retain its performance for years, even under extreme conditions. This makes it an ideal choice for applications that require reliable power sources that can be stored for long periods without significant degradation.

4. High energy density, high capacity.

Moreover, the battery pack's high energy density allows it to provide a significant amount of power in a relatively small package. This is crucial in applications where space is limited, such as in handheld devices, sensors, and remote monitoring systems. The compact size and lightweight nature of the battery pack also contribute to its ease of use and portability.

5. Safety. 

Safety is another crucial aspect of this battery pack. Li-SOCl2 batteries are known for their stability and low risk of leakage or explosion. The Er18505 SPC1520 model incorporates additional safety features to ensure reliable and safe operation. This includes the use of high-quality materials and rigorous manufacturing processes to minimize the risk of defects or failures.
