Camcorder batteries? - camcorder batteries

Hello, I have a Sony digital 8mm camcorders. He is 10 years, but do not see much. I have two batteries, the wine, for about an hour and the second is good good for about three hours. The second battery is manufactured by Sony for Sony, if it were not for the market. Problem if both batteries are fully charged, and they act as if they were about to die. So the three hours battery is completely charged, reading 2:56 that states that two hours and fifty to six minutes at full load. Then, when I said that the use of the battery works well for ten minutes, then cut, battery low indicator. The battery supplied with your camcorder does the same. Why is this so? Thanx, Robert
