RE: BAttery discharging
Hook up the battery press the red battery until the right battery you ar cycling come up then press the green button. Then press the yellow button untill you see cycling comes up discharge/charge once this screen appers hold down the green button until it starts to discharge. When it finfish discharging it will start charging in the bottom right hand corner of the screen it will show the mah the battery ahs held when fully charges so if you are charging a 2000 mah battery and this bottom right number is close to 2000 you know that the battery is good and fully charged.
