Query: sloooooow charge and won't hold a charge for a reasonable amount of time

I'm very disappointed with this purchase. The charger is incredibly slow, only usable for overnight charging, and the batteries won't hold a charge for any decent length of time. If I put freshly charged batteries in my camera, I can take a good number of pictures, but if I leave the batteries idle for any length of time, say a week, they're dead the next time I want to use them.
