Battery charging problems

I recently bought a used Acer Aspire 5100 and bought two replacement batteries. Since I received them I have been trying to get them to charge without much success. I have discharged and tried to recharge them at least a dozen times. Most of the time I can only recharge them to about 37%. Occassionally it gets up to 57-65% and then the next time it is back only to about 37%. The battery that I got with the computer charges completely to 100% but I don't know for how long which is why I got the spare batteries. What is wrong?

    Hello,

     

    For information, the original batteries are 6 cells - 4000mAh or 8 cells - 4800mAh.
