All may not be lost. To "awaken" stored cells you need to exercise them a bit. It helps to start with a 0.1C charge for 16 hours. Then you need to discharge at 0.5C down to 0.8 volts. Then you need to discharge again at 0.1 amps to 0.8 volts. Now you can do another 0.1C charge for 16 hours. Follow this with a 1C discharge to 0.8 volts, again another discharge at 0.1 amps to 0.8 volts. Now you can charge normally.
In stubborn cases you may have to do a few cycles of normal charges followed by normal discharges to 0.9 volts, but this "conditioning" usually gets you back up to very close to the same performance that you had before.
I had a set of cells that were really stubborn. It took just over 50 cycles to bring them back to normal performance. Now they are working fine. The first discharge on these cells, after a forming charge, gave me around 800 mAh. These were 2400 mAh cells. At a 3 amp discharge rate, these cells started at around 700 mAh and recovered to around 2100 mAh.
Before you throw these cells out, you may be pleasantly surprised that a little time spent cycling them may produce "like new" performance.
C är den nominella kapaciteten för batterierna enligt tillverkaren, i ditt fall 2000mAh, för att göra detta behövs en "dum" laddare som laddar med ca 200mAh.
lessnade och köpte ett 4pack GP batterier istället

2700mAh.. men det kan ju vara bra att veta i framtiden!
Laddaren jag har är en Nikon MH-70, som följde med kameran...
Hur många mAh den ger ut har jag ingen aning om men den kostar ~4-600 och ska ladda 2000 mAh batterier på ca 2½ timme så den bör ge ut 800mAh iallafall
