G&G airsoft problems?

i have a G&G GR16 blowback airsoft gun with a Intellect AA 2000 MaH. one day i was out firing it (in the prone postition) when it stopped shooting, so naturally i figured the battery was dead. i let it charge and i reconnected it to the gun, still nothing. no click or anything when i pull the trigger. i have a smart charger so i know i didnt overcharge it. i checked the fuse, its fine. i check the connections to the motor. theyre fine. i open it to see if the wireing is cut, its fine. i dont see anything wrong with it yet it still wont fire. ive only had it for a month and a half. im unable to check to see if its the gun or the battery because i dont have a spare battery :(
