Tracy, any idea how old that battery is? I read 18 months is average for a battery. Our local lumber company sells a "generic" batterythat is an exact fit for only $17. That's a cheap fix or test whichever way you want to look at it. Also,If you have electricity acess you can hook a battery charger to it to determine if that's the problem. Or remove the battery and take it to your garage and try to charge it. Note: When mine acted up I replaced the battery and problem solved and....it was exactly 18 months!! Let us know what you find out. Always need knowledge about these feeders. There may be a TH feeder trouble shooting guide on the WWW somewhere??
18 months, plus or minus a couple, is what I've gotten on my TH feeder batteries. That's usually the problem I run into, other than plants growing in the path of the feed and fire ants.
However, I did experience one instance where the solar panel was defective and had to be replaced. If you never see "charging" on the Menu, even when you put in a new battery, the solar panel is likely the culprit.
