Ryobi are actually the first batteries that I genuinely dislike; I have 8 year old Black & Decker drill whose battery still works great. Similar experience with some other manufacturers. But we went all-in on Ryobi at Home Depot a few years ago, and we now have to buy 2-4 new batteries a year. Then after 12-18 months, the battery shows as defective on its charger.... brutal.

(probably less-than-average usage patterns as we are lazy house owners; stored inside, not abused)

That pretty much echoes the reputation Ryobi tools have. ie. the tools themselves are really good but the batteries don't last.
