Lithium Ion (L-Ion) rechargeable batteries are a very common technology employed in many consumer electronics. The below suggested best practices and general information will help you achieve the maximum battery performance over the product’s expected lifetime.
The typical estimated life of a L-Ion battery is 300-500 charge cycles (fully charged-fully discharged-fully recharged) or 2-3 years, whichever occurs first.
L-Ion batteries will slowly discharge when not in use. Do not leave batteries unused for extended periods of time, neither in storage nor in the product. When a battery has been unused for 6 months, charge or dispose of the battery based on charge status.
Rechargeable L-Ion batteries have a limited life and will irreversibly and gradually lose their capacity to hold a charge. Run time decreases as the battery loses capacity.
Elevated temperatures can cause permanent loss capacity and negatively impacts the cycle life. Whenever possible, keep L-Ion batteries in cool conditions to preserve the capacity of the cells.
