Battery won't hold a charge. the red light is flashing on the charger so based on the other coments on this site, I have a bad battery. sounds like Worx has a on going problem that they aren't addressing

I had the same issue with my Worx battery.
Check to see if you are eligible to receive a new battery replacement:

Worx has supplied cheap batteries for years, even if you buy a new battery it will fail very quickly. Ditch the poor quality trimmer and buy a gas or plug in trimmer from your local hardware store, it will save you a lot of agony, trust me I've been there.
