(More customer reviews)I bought these batteries 2x8pack in early December 2008. The batteries are listed on Amazon as having 2300mah capacity, but the one they shipped were actually 2650mah. (That was the good news).
It was surprised that the batteries did not seem to hold charge for more than a few days... To be sure about this, I bought a La Crosse BC-900 charger and tested the batteries.
I refreshed and charged the batteries in many different ways. The number of cycles and the speed by which the batteries were charged/discharged did not seem to influence the measured capacity.
The BC-900 told me two things.
1) The true capacity is somewhat below the 2650 that is listed on the batteries. All were measured to be in the 2350-2570mah range.
2) The batteries loose their charge very quickly. Judging from betteries I had charge a week earlier, the batteries had lost about 50% in a week.
My conclusion is that these batteries are only valuable if you are using them in power intensive devices - devices that will use up the full capacity within days of them being charged.
It will be waste of your time to charge and store them for more than a week before use... These should be recharged right before use.
Called Duracell about the problem... and they were sufficiently helpful for me to add a second star to my rating.
