AA (14500) 3.6v Lithium Ion Batteries
Lithium Ion (li-Ion or LiCoO2) 14500 batteries are the same size and dimensions as regular AA batteries. AA Li-Ion batteries have a 3.2-3.7v (depending on Lithium type) rating and are commonly found in GPS units, diving equipment, and high powered LED torches and lighting systems. An AA Lithium Ion battery can be charged using one of Mr Positives Li-Ion battery chargers. These cells cannot be charged using a conventional AA battery charger. Doing so will cause irreversible damage to the battery.
Please note that AA lithium Ion rechargeable batteries are NOT a direct replacement for conventional AA batteries, they carry twice the voltage and are designed for specialised equipment. Do not use a Li-Ion rechargeable battery in conventional devices such as TV remotes, toys and digital cameras.
