The Samsung ICR18650-28A cell is 4.3V rating 18650 Battery cells for those request high drain applications with 6A discharge current. At 4.25V you can get 2750mAh while with 4.3V it is 2850mAh. In our cycle life testing, 2A charge 2A discharge capacity falls from 2350mah (because we apply 0.5A cut off charging model, which doesnot release the capacity in full) to 2100mah after 510cycles, say 0.45mAh per cycle drop only. This is very good cell if you use it at 4.2v only and donot care about the capacity potential unused.
