And I got a 7.2v battery(of course I got a connector):
http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=1365

The problem is that I don't know how long I should charge the battery. Is there anyway I can calculate the charge time by using the specs. or something?

Status: offline 		yeah, so if you figure out how much you took out of your pack roughly then times that by 140% and then divide that by 375mA

so if you used 1800mAh then times that by 1.4 you get 2520mAh and then divide that by 375mA, or about 6.5 hours

Basically with these packs you should notice the pack get slightly warm when it's done charging. If it's not warm when you take it off the charger, then it's probably not charged.
