Battery Pefrorm Reset

[qazthinkzaq]

Hi,
I have a ultrabey battery wich have 79% of its original capasiti.
I used Perform Reset and now i have 56% of capasiti.
I did it twice the batteri recharges then charge and thats it no message. I didn't use my compurer for about 5-7h.
Can i Fix it?
When i used Perform Reset is there a OK mesage or something like this?
Best regards
