As a homeowner I’ve had Ryobi lithium batteries for over a decade. Other than having added a couple battery packs from deals and a couple batteries from tools, I’ve not had a single one of my batteries fail. All are being stored at the maximum charge. Some don’t last quite as long these days, to be expected with age, but not one has actually failed even from being dropped off ladders onto concrete. I did, however, have a Dewalt at work that died from falling 4 feet to the carpet floor. I’ve only had one Ryobi tool fail in that time, and those circumstances were questionable since someone had borrowed it.

Experiences are localized and subjective.
