I have a 4 year old Dell XPS 15 and I just replaced the Li-ion battery for the second time. I guess that's not shocking.
But Dell wasn't even selling replacement batteries the first time. I did get a free one from them because they had a problem with the original batteries swelling. That replacement didn't swell, but the runtime had decreased dramatically. The no-name replacement (bought from Amazon) fit perfectly, and looked just like the Dell battery except for a sticker that I'm pretty sure covers the Dell name. It's a pretty nice laptop and I can't guarantee I'll be ready to retire it 2 years from now when this battery will probably need replacing. Amazon still has them in stock, should I order another one? Or is putting a spare battery on the shelf stupid, will it just gradually discharge and go bad? It's not very difficult to change the battery, would it help to swap batteries every 6 months or something? I actually saw something on the Internet that Li-ion batteries should be stored partially not fully charged. And of course they can't put anything on the Internet unless it's true.
