This is a test of old, ordinary non-LSD Sanyo cells, branded as 2700 mAh typical, 2500 guaranteed. Cells are courtesy of Nikola Goranov. The ones tested here are three years old, which, judging from my experience, is not "too old" for Sanyo cells. Yet, this is not a real test as I only measure two cells here, and I can't really discharge them fully due to limitations of my device. Anyhow, the one-hour test showed 2300 mAh, which is one of the best for the AA format, and is expected given that the cells aren't LSD. The 5-day self-discharge rate is acceptable at 5%, but the one-month is worrying at 16%. Even though, the cells had almost 2000 mAh there, which is more than most LSD brands, too - but the nice thing about LSD is that capacity levels out after some time, whereas the non-LSD varieties continue to drop more and more.
