Hi guys!
I've previously testedprismatic 103450 batteries from Panasonic and Maxellmade in Japan. This time i've tested the third cell from Japan - Sanyo UF103450PN. Like its competitors it's a low-drain Li-ion cell mainly used to power small devices and build battery packs.Queen Batteryalso offers this cells with protection PCB.
The video version of this test for those who prefer watching rather than reading:
Tests were done usingZKETECH 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 theIEC61960-2003standard 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 23.5-24.5C. To be sure in results i've done each testminimum twice.
SANYO UF103450PN
The cell which i've tested has the following marking:
Front: C SANYO TD UF103450PN
Back: 12231032
Specifications from UF103450PNdatasheet:
Rated capacity:1880mAh at 20C
Minimum capacity:1880mAh at 25C
Typical capacity:2000mAh at 25C
Nominal voltage:3.7V
Standard charge current:1.88A (1C)
Charge end voltage:4.2V
Charge cut-off current:37.6mA
Max. dischg current:3.76A (2C)
Discharge cut-off voltage:2.75V
Weight (max):38.5g
Measured DC IR is 52m? on fully charged cell at 1C/1.88A
The measured weight of my UF103450PN cell is 37.05g
Capacity test results:
At 0.2C (0.38A) capacity is slightly higher than 2000mAh and energy is about 7.62Wh. At 2A discharge UF103450PN's capacity is almost 1900mAh and at 3A just a bit lower than 1860mAh - nice result in comparison withMaxell ICP103450AHRbut not withPanasonic NCA103450.
CONCLUSION
SANYO UF103450PN is a good cell which complies to its specs. If we put together all three 103450 cells Panasonic would be the best, Sanyo the second and Maxell the outsider even at 4.35V charge. Queen Battery sells UF103450PN for $5.15/cell without shipping.
