Two more 16340 arrived the other day ..

Graph shows the results for 5 ( 0.5A ) discharge cycles : ( 0.5A discharge to 3v termination )

I also did a current discharge test after the discharge testing :

Efest 16340 : 1.79Amp

Olight 16340 : 1.53Amp ( Battery Dia - 16.3mm , Length - 34.2mm )

Keepower 16340 : 1.67A ( Battery Dia - 16.4mm , Length 35.7mm )

Conclusion:

The Olight comes closest to factory capacity claims ( 650mAh ) returning 613mAh in one test , while the Keepower with a 700mAh capacity claim falls rather far short with a 579mAh best test . Even though the Keepower battery discharges at a higher current , I like the Olight better . The Olight is smaller , has better capacity and should fit inside a lot more flashlights . Both batteries appear to be decent quality , so check out the results and make up your own mind .

Thanks OL. What equipment did you use to test and record your results?

Discharge was done with a Turnigy Hobby charger - Discharger .. http://hobbyking.com/hobbyking/store/__7523__Turnigy_Accucel_8_150W_7A_Balancer_Charger.html

For testing current , just a hot-rod flashlight ..
