SANYO UF103450PN capacity test

I've previously tested prismatic 103450 batteries from Panasonic and Maxell made 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 Battery also offers this cells with 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.

SANYO UF103450PN capacity test results:
SANYO UF103450PN datasheet pdf
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 with Maxell ICP103450AHR but not with Panasonic 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.

Samsung 50E capacity test - 5000mAh or not?

Samsung INR21700-50E is a 21700 size cell which is being sold as 5000mAh one while in its official datasheet the capacity is mentioned as "Min. 4900mAh". I've tested it to find out it's real capacity. The battery was bought from my reliable supplier ( Queen Battery ) and tested  with  ZKETECH EBC-A20  and a self-made battery holder.

Samsung 21700 battery battle: 50G vs 48G vs 50E

Samsung has a good lineup of 21700 Li-ion batteries and when i tested INR21700-50G i thought it would be interesting to test INR21700-48G cell too because the new batch of 48Gs came in green heat shrink tube (the version i tested before was gray). Then i added 50E results to comparison as they are very close in capacity and max discharge rate. The batteries were bought from Queen Battery which is my reliable supplier of genuine cells and tested with ZKETECH EBC-A20 and a self-made battery holder. It's a PC-connected battery tester supporting 4-wire measuring and discharging at up to 20A. 50G and 48G cells were tested using my battery holder v.4.0. A detailed video about it is available on my channel. I've followed all the prescriptions of the IEC61960-2003 standard concerning battery's capacity measurement.

Li-ion 21700: LG M50 5000mAh vs Samsung 48G 4800mAh discharge capacity test

Hi guys! I've tested two high capacity 21700 cells - LG M50 (5000mAh) and Samsung 48G (4800mAh). The latter i had already tested before and the re-testing of another cell showed almost no difference with previous test results. The M50 is a new cell which is being sold as 10A one, but in its datasheet the maximum discharge current is mentioned as 7.28A. Nevertheless i've also discharged it at 10A to look at it's behavior. The cells i've bought from Queen Battery . As always, I've tested with ZKETECH EBC-A20 and a self-made battery holder. It's a PC-connected battery tester supporting 4-wire measuring and discharging at up to 20A.
