Im trying to charge my Ryobi battery but the charger keeps blinking green and wont charge the battery, why??
My Ryobi 18V One+ charger blinks green while it's charging. When the battery is fully charged, the LED goes to a solid green. However, one battery recently had a faulty cell. After several hours on the charger, the green and red LEDs both were blinking. That indicated that the battery failed late in the charging sequence. It didn't fail the initial testing by the charger. The other battery I charged that day charged fine.
The extended capacity batteries can take 12 hours to charge in my experience. The regular batteries take less time. The charge time will depend on the battery chemistry(The older NiCd batteries take longer to charge then the Lithium batteries.)
I hope this helps. Assuming you aren't dealing with a cold or hot battery or charging environment, if you have any suspicion about a faulty battery, replace it.

(Note: I have a 12V drill as well. Those batteries takes longer to charge for the same relative capacity than the 18V NiCd batteries.)

Does this happen to both batteries or just one if it is both then i would suspect the charger is bad and not the battery

More than likely a defective battery sinse the other ones charge fine..
Bring it back for exchange of another one..

Bothights on indicates a problem with the battery. You cam try cleanibg the battery terminal with a Q-tip moistened with alcohol. Allow it to dry completly before tryin to recharge. If that doesn't work the battery may be defective or broken. If it was dropped that could cause the damage.

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.

I had the same problem. No need to repeat it here, but I found this solution worked for me. In case I didn't embed / post it right, copy / paste this into your browser: http://youtu.be/GhRQZEeQzP0 Hope that helps
