yes.... you can use any 6 volt battery. i use a 6 volt from an emergency lighting system. 6 volts is 6 volts the size of the battery does not matter. the more amp hours the longer it will last. for the guys that have cameras that take 8 d sized batterys which equals 12 volts they can hook up a 12 car battery and run the camera all season. only bad thing is the weight and draging it into the woods. this alsowould notvoid your warranty.
