I have recently placed an order. I am wondering at the time of installation will I need to charge these balances or are they pre-charged? If I need to charge them is there a recommended charge per balance.

You will have to charge the balances, I usually give the spiral three to four turns to start. I then take precaution by trying the window sash to see if it will operate properly. Then I adjust it accordingly, adding more turns as needed.
