Shelf life

Normally, the lifespan is 1 year. If the manufacturer's manufacturing level is not high, or the quality control is not good, its lifespan will be greatly shortened. The batteries of domestic first-line brands can basically guarantee this life. If the use environment is very ideal (sealed, normal temperature, no interference such as moisture), its life will be further extended, up to 3 years. Domestic lithium manganese dioxide batteries have been continuously improved in recent years, and their performance is getting closer to the level of Japanese batteries.
