ER321270S High temperature LiSOCL2 Battery Advantages

1. Super high temperature performance

Super high temperature performance usually refers to the ability of the product or material to maintain its normal performance and function at high temperatures.  In the field of energy, the battery with high temperature performance can ensure its normal operation and long service life under high temperature conditions. In order to achieve super high temperature performance, the design and material selection of the product or material need to meet certain requirements. high temperature Battery LiSOCL2 primary battery ER321270S will be work well in the environment of 150 ℃ for a long time.

2. Small self-discharge: 

The self-discharge rate of the high temperature Battery LiSOCL2 primary battery ER321270S is less than 1% at room temperature, and the storage period can reach 10 years in an environment below 35 °C. which will make sure the battery have longer storage life, according to Long-term production inspection and customer use tracking, the life span can reach 10 to 15 years.

3. High capacity

Stable high operating voltage and high capacitance; High energy density,high stable current.

In the field of battery technology, high energy density battery materials can store more energy in a limited volume or mass, thereby increasing the capacity and energy density of the battery. 

4. Safety

Safety value design and material selection are exquisite, safe and reliable, and make you worry-free on the explosion risk.

Battery safety is a very important issue, especially for rechargeable batteries. A battery explosion or fire can cause serious personal injury and property damage. Therefore, battery safety has always been a key issue in the field of battery technology. The battery safety issues mainly include: battery short-circuit, over-discharge, battery mechanical damage and use environment.

The high temperature battery ER341245S ER341270S battery is internally designed to prevent short circuit, over-discharge protection, and can be used in high temperature and high humidity and other harsh conditions,Safety, reliability and performance at high temperatures up to 150 °C.

5. All stainless steel outer body, metal glass sealing structure, non-combustible inorganic electrolyte.
