Seems I had completely forgotten about this category. Well...
When I first got the MacBook, I mentioned that it needed to have the battery serviced. That was over three years ago.
In July 2018, I purchased a new battery for it. The old one finally got to the point that it was swelling and pushing the track pad up, causing it to break through the deck.
Otherwise, I'm using it still, transporting it back and forth to the office for work and using it at home for general computing needs.
