SONY US14500VR2 is the second 14500-size Li-ion battery which i've tested. 14500 is the same AA size we used to see in alkaline and Ni-MH batteries. It assumes 50mm in length and 14mm in diameter. SONY US14500VR2 is rated at 680mAh (min) at 3.6V and comes without protection PCB. Tests were done using ZKETECH EBC-A20 , which supports up to 20A discharge, 4-wire measurement and is PC-connected. I've used version 3.0 of my battery holder based on 0.5mm thick pure copper terminals I've followed all the prescriptions of the IEC61960-2003 standard concerning battery's capacity measurement. Before each discharging cycle each battery was charged at standard current mentioned in its datasheet to charge end voltage (4.2V) (cut-off at 0.1A, which is the lowest supported by EBC-A20). Before each discharging or charging i've held a 1-1.5hrs pause. The environment temperature was 23.5-24.5°C. To be sure in results i've done each test minimum twice (usually 3-4...

Everyone knows that UltraFire and other *Fires are Chinese brands who sell re-wrapped crap marked as 6000mAh, 8800mAh or even 12000mAh Li-ion cells but TrustFire doesn't use crazy ratings like that. 14500 is the same well-known AA size - 14mm in diameter and 50mm long. 900mAh looks pretty real for that size so let's check is it real or it's just another *Fire.
