How Long Do Lithium Batteries Last? (The Complete Answer)
Wondering how long do lithium batteries last? Get the definitive answer on lithium battery lifespan, factors affecting longevity, and battery care tips in our guide.
This date is a useful reference point for estimating the battery's shelf life, which is usually specified by the manufacturer. Shelf life can range from a few years to more than a decade, depending on the battery type and storage conditions. How Can Lithium Battery Shelf Life Be Extended?
The cycle life of a lithium-ion battery refers to the number of charge and discharge cycles it can undergo before its capacity declines to a specified percentage of its original capacity, often set at 80%.
Lithium batteries can hold a charge for several months when not in use, thanks to their low self-discharge rate of around 2-3% per month. This makes them ideal for applications like backup power systems and seasonal equipment. However, factors like storage temperature and battery health may affect performance. 4.
In contrast, Lithium Polymer (LiPo) batteries—commonly found in drones and remote-controlled devices—typically offer a lifespan of around 2 to 5 years, while Lithium Manganese Oxide (LiMn2O4) batteries, used in power tools and specialized equipment, generally provide a lifespan of approximately 3 to 7 years.
