Meanwhile, I have all 64 of these batteries in use. In Gene set to standard batteries, is not discharged this almost. While I can not tell you how this looks after storage for 3 years, since I load the batteries immediately after use and then insets within the next 3 to 4 months, but at least during this period, I have not experienced any self-discharge.
For longer storage periods but I would to my past experience trust the manufacturer's instructions.
As capacity batteries are listed as printed with min.1900mAh.
However, according to charger (BC-700 Technoline) the actual capacity varies between 2.32 and 2,39Ah. This is, after all, almost 25% more capacity than expected.
Even after 3 years show that the oldest batteries still in full swing. That was not to be expected in a specified number of charge cycles but.
I use the batteries by the way both as cross-country skiers in remote controls and clocks (analog, is now running more than 2 years), as well as utilities in portable radios and flash units (for example, DSLR).
The latest generation is no longer the way of Sanyo, but Panasonic, Sanyo has been taken since.
