Review on Power Up Your Ryobi One+ Plus Tools With An 18V Replacement Lithium Ion Battery - Works With P102, P103, P104, P105, P107, P271 by Sean Sitton

I was glad to read the positive reviews on this product. I can't say how long they will last since they are not OEM replacement parts but, the price was outstanding compared to the home center. We use these batteries for a Ryobi drill and weedwacker. Originally, we had 2 Robyn batteries. One stopped working quite some time ago. The remaining battery could not last through edging around a few trees, flower beds or sidewalk. We will do one more edging before all lawn maintenance stops for the winter. We will be anxious to see if this battery can last long enough to do the job without stopping to recharge and of course, in spring will it perform & do the job in its entirety on one charge. Hoping it won't start to lose significant power after several hard uses and we are back to square one.
