None of the batteries in any of my laptops work anymore.... I have zero choices to vote for!
I'm in the same boat. I have two old Dell Inspirons and the battery has failed in both. I just run them off of power, and hibernate/suspend-to-disk when done working (which I have configured to happen automatically when I shut the lid). It's not as nice as having a working battery, but it's useable. I could buy new batteries, but last I checked, the official Dell ones are several hundred dollars, and third-party knockoff ones are almost a hundred. That's not worth it for my 10 year old laptops that I got for free.
