Redback – BATT LI-ION 18650-2.5A HI GHOUT

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).
