18650 2500mAh High Output Li-Ion Rechargeable Battery

Safe and Reliable Rechargeable Battery Solution

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. They offer a higher maximum current output than the standard 18650 batteries. 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.

Common applications for 18650 cells include: 
Laptop computers 
LED flash lights 
Electric vehicles 
Power tools 
Converting AA or AAA powered products over to higher performance (providing voltage matches). 

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.
