Just got me one of these, but the instructions are quite brief, so I have a couple of questions. First, the power supply has a red light on it, I assume this will change to green once the battery is fully charged? I noted the light glowed green before I plugged it into the AC. Second, with a loss of power, will the pump still maintain its normal program, or does the switch to battery power automatically put the pump into a lower power state so it will last longer on the battery? Thanks!
