Could have also been B-grade (or worse) 20Ah cells. Bear in mind there is normal variability in there too. The officially stated nominal capacity of the "20 Ah" cell is 19.6 Ah, but the very best ones will weigh in at 21 Ah.
oatnet said:I would believe that the large quantity of 20ah and 16ah cells I bought from cellman in 2009 were experimental or preproduction - and he only ran out of them because my second order bought every 20ah and 16ah cell he had left.
wb9k said:I'd have to say these were from experimental builds [...] possibly precursors to the 14Ah cell I'm familiar with today.
wb9k said:I'd have to say these were from experimental builds. The cells look like the real thing, but the part numbers on them are very strange, and looking them up in our system yields no results. That, and the 400g weight called out by Oatnet suggests to me these were experimental builds of lower Ah cells, possibly precursors to the 14Ah cell I'm familiar with today. The odd dimensions of some cells rings true as well--I've seen stuff like that around the office before. Any marks on the center of the cells' front faces, or does the linked photo show all the markings on these?
wb9k said:Outer dimensions are same as the 20Ah cell, only it's thinner. Not sure what the weight is offhand.
