Lithium ion batteries are one of the most common rechargeable batteries in portable electronics. They are known for having one of the best energy densities, no memory effect, and a slow loss of charge when not in use, in comparison with other chemistries of rechargeable batteries. These AAA-sized batteries can be used in a variety of applications where standard AAA cells are called for, but always double check the specs before using a Li-Ion cell in a device you are not sure on.
