Unwrapped Unmarked Cells (Likly Sanyo NCR18650BD 3Ah 18650 Cells

My supplier is calling these cells Sanyo NCR18650BD however all my research has netted zero evidence of a cell by that name existing. I'm open to suggestions if anyone has further insight on the model. I believe they are actually Sanyo NCR18650BD cells based on my test results. At 1A discharge ~90% are testing at 2.8-2.9ah At 5A discharge ~90% are testing at 2.4 - 2.5ah The other 10% varies pretty wildly. The cells are standard 18650 size with a button top. We are guaranteeing these cells at 80/80(AKA at least 80% of the cells will have at least 80% of 3.2Ah capacity at 1A discharge rate) PLEASE READ! Due to the close proximity of the positive (button) terminal and the rest of the battery acting as a negative terminal we strongly recommend that the cells be wrapped and an insulator ring be added before they are put in a charger. If used incorrectly they will short. Last image shows the Positive (red) and Negative (blue) sections of the battery. The specs for the Sanyo BF cells are
