These high performance 18650 lithium ion 3.7V batteries offer high performance and long life from a compact package. They are 18.6mm in diameter and 65mm long. Lithium-ion rechargeables offer excellent properties for use in consumer devices, including excellent energy density and low maintenance. Lithium-ion do not suffer from memory effect and possess no regular cycling that batteries often require to extend their service life.
Note: These are an unprotected cell and should only be used in situations where a charging circuit is controlling the discharge and recharge of the cell. Incorrect usage of lithium cells can cause fire and advice should be sought before utilising them in any circuit for your project.
