Despite the apparent lack of love for the Ryobi Plus One battery tools I actually like them pretty well except for one thing. They have a problem where the batteries easily get to a discharged state and won't take a charge. The "smart" electronics prevent it from charging despite the battery actually being fine. I wasted a few expensive batteries before i learned that there is a work around.
I find they will take a charge if I directly charge the cells even for a few seconds bypassing the electronics. Once I do that they will charge normally again in the regular charger. To do that I just open the case of the battery and connect the main plus and minus on the cells to another ryobi battery pack for 10 seconds or so. It is a fairly minor annoyance to do that once in a while and IMO worth it given the cost of new batteries.
Google will provide lots of details and probably better more detailed directions.
Bottom Line:
Don't throw away those Plus One batteries when the charger shows them as bad they can probably be revived. I have not noticed that the revived ones have been any the worse than the others in my rotation.
