How to use

Install the 18650 battery in devices that specify compatibility with 18650 Li‑Ion cells and observe polarity markings. Use a compatible charger designed for lithium‑ion batteries and follow the charger manufacturer’s instructions. Do not attempt to force the cell into a compartment that does not match the 18650 size. Allow the battery to reach room temperature before charging if it has been stored in cold conditions.
