The SUNJ primary lithium battery used in smart meters adopts unique corrosion-resistant materials, with a stainless steel shell and cover, excellent low-temperature working performance and stable working voltage. The internal use of non flammable electrolyte makes it safer and has a longer working life compared to other primary lithium batteries. The annual self discharge rate at 25 ℃ is less than% 1, making it suitable for complex working conditions such as extreme high and low temperatures and high humidity.

As one of the major lithium battery manufacturers, SUNJ LiSOCl2 batteries have unique performance advantages, including higher capacity and energy density; A wider operating temperature range (-55 ° C to 85 ° C); Widely used in automatic meter reading systems (AMR), advanced metering systems (AMI), smart water meters, electricity and gas meters, and wide area network fixed communication equipment.
