I have about fifteen RYOBI P103 batteries which when placed in the charger do exactly what they are supposed to do as far as the red light blinking and then the green light blinks for about 2 minutes and turns a solid green indicating a full charge but has no charge. What causes this?

I was recently told that the lithium ion does not like cold temperatures so you may need to bring the batteries and charge into a warm location and wait until they reach a warm temperature and then charge them.

I've open the charger and found that Q4 is open. But they have removed the part number from the component so you can't get a replacement.

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!

Yes you can that is an automatic charger when it is fully charged it shuts down the charging portion but keeps the charged light lit however this does not effect the battery.

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.
