Cyma Ak I Am Having Trouble With My Airsoft CYMA AK-47?

I am having trouble with my Airsoft CYMA AK-47? - cyma ak

I'm having problems with my Airsoft CYMA AK-47. Press the shutter button and drag the fire, but nothing. I think because I took the battery ... responsible for approximately 12 hours = (.
I do not think this would apply to them, but my cousin took it and ran a day earlier, and when I was back in security, which the security is no longer destroyed ...
As these events have taken place, the airsoft gun problems. I tried to recharge the battery and still does not work. I hope that you can quickly get my hands on one so my friends CYMA battery that you can attempt.
Thank you.
