Lithium iron disulfide (LiFeS₂) batteries are known for their excellent high-rate discharge performance and lightweight structure. These features make them an ideal power source for portable and high-drain devices. The LiFeS₂ batteries provide a stable 1.5V output and operate efficiently across a wide temperature range, ensuring consistent performance even in harsh environments. With a shelf life of up to 10 years and superior energy density, LiFeS₂ batteries are well-suited for demanding applications such as digital cameras, smart door locks, wireless sensors, and backup power systems. Their long-lasting, maintenance-free design makes them a preferred choice for both consumer and industrial use.
