I really prefer using rechargable batteries instead of 'Throw away' ones. Not only because it does good for the enviroment but because they always seem to last longer. This is the case with these batteries. I bought them purely for my PSP dock which seems to go through a set of batteries everyday even with hardly any use! These batteries are really fantastic. I just charged them in a Uniross charger and they were done in around 20 minutes. Took them out of the charger, placed them into my dock, and I was amazed by the power. The volume was far exceeding the level capable from the standard batteries.
I think that 1000mAh is the most powerful AAA batteries you can purchase and this is probably why they are so powerful. So, at this price you really cannot afford to miss out on this fantastic opportunity, as they are very expensive in the shops. Just buy them, you won't be dissapointed!
