Quick battery question

[UndeadGhost]

Hey this is just a quick one but there's like 2 people in the tech section and I would really appreciate this answered quick. I just got a ics cxp and I have the special numchuck battery for it at 1600 mah. all my other guns are large type but I managed to find an old mini type charger with the specs: 9.6v 450maH on it. if the battery was completely dead how long do I charge for? safe to leave overnight?
