Check the battery with your multimeter. If it reads below 36 volts (or whatever the cutoff point is) it may be damaged. But before you run off and buy a new one, use the multimeter to check the voltage from the charger.
Or borrow a good battery and see how your charger behaves.
that way, you can identify the cause of the problem

Hi, Thanks for getting back to me. The yellow and blinking red indicate a defective cell. Since it has lithium cells and is that new any repair to it would be a waste of your time. Ryobi tools purchased in 2008 have a 2 year warranty. I am guessing you probably got it at a home depot and you should return it under the warranty. All new Ryobi tools have a three year warranty. Good Luck! and Thanks for using fixya!

I have had exactly the same problem, and have replaced both the charger and the battery.
I think the problem lies in the contacts between the charger and the bayonet and the battery..
Soooo
I put a couple of peices of folded paper behind the battery, making a very very snug fit.
then, (this is a bit fiddly)
i carefully folded a slim peice of paper to wedge behind the charger pin and the back of the bayonet, so the pin is pushing against the front of the bayonet.
( to do this, position the paper over the pin and push into the socket at the same time.)
works like a treat :)
if you had exactly the same problem, it will be due to the charger wobbling around about the socket.
this ensures a tight fit and means it maintains contact all the time.
good luck, and i hope you haven't started to tear your hair out quite yet.

My charger do the same thing. I talked with the service people at Ryobi who said that the red led never goes out no matter how long you charge it. They suggested just charge it for 12 hours and then disconnect. Pretty dumb system, but that's apparently the way it is.

sound to me like you have a bad battery, a lot of ryobi batterys don't last like they should i have had the same problem, but my battery was less than a year old and i took it back and they give me a new one.

Worx has had issues with their chargers and their batteries. They don't seem to last as long as the machine does. A simple voltmeter test of the charger and any battery will tell the story. The charger's output rating should be printed on it and the battery also. Touch test leads from voltmeter to the two and check.
