My relatively new TH 70 lb fish feeder stopped working, despite battery charging & rated as "good." When I called about the problem, I was told this is often a battery issue. The voltage is fine, and that's what is measured as "good", but the amperage is not measured. Low amps means the motor doesn't work, regardless of voltage. They recommended trying a new battery to see if this is the problem.
Don't know if this will fix it, but I did want to pass this along to my fellow pondmeisters.
I talked to them about the batteries. It seems that they are having battery quality control issues too. I don't know where they are sourced from, but they said they might last a year, or 7 years - it's strictly the luck of the draw. All I can say is that during the winter, turn all the feed stations to "off" if you aren't feeding the fish and leave the battery plugged into the solar charger. If you want to bring it inside, put it on a trickle charger or a battery tender. I had 2 batteries go bad on me and they were slightly over a year old.
