Lithium Ion Rechargeable Batteries and Chargers

Lithium-ion (Li-ion) batteries are a type of rechargeable battery. They are currently one of the most popular types of
battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of
charge when not in use.

Though these batteries are about the same size as the common one-time use batteries, most of the Li-ion batteries
produce 4.2 volts of output when fully charged, so they will instantly overpower and destroy the devices which are not
designed for Li-ion batteries. Check your application specs before you use these batteries.

The 5 digit number is deciphered like : 18650 = 18mm ( diameter ) X 65mm ( length ) where the last ' 0 ' stands for
cylindrical cell. Learn more about Li-ion Battery.
