Burgermeister- Why are you using a 4.5ah battery? The ADF-75 comes with a 7.5ah battery. If it is a 4.5ah battery that could be part of your problem. Also, if your battery discharged all the way and was like that for more than about 36hrs it will not hold a full charge for very long.
I am not trying to be difficult but with the new panels and timers battery life has not been a problem in our testing. Our testing was equal to more than 4 months of the feeder going off 2 times a day for about 7 seconds with no battery problems.
I can get you a new panel and battery to see if that works.
