Romero:

I have the same cell by the same manufacturer. Its several years old as yours appears to be, but still going strong after about the same very light damage to one outside cell. It has had around 15 cycles on it after the damage, always charged in a ceramic flower pot. Regardess, you take a chance on any damaged li-po. Give it a standard charge outside the house and leave it there after full charge. Let it sit for several hours and then disccharge & check out the charge. If its still around 1320 mah you are at your own risk. Keep it in a safe fireproof box at all times as you should do with all your lipos when overnight in the house. ENJOY
