If you're on hn, you might not be opposed to replacing the battery yourself. Here's a teardown that exposes it [0]. It may be difficult to source a replacement battery, I would check aliexpress/ebay (usually better than mouser/digikey for these). At minimum, you would need some tiny screwdrivers and a soldering iron (battery wires soldered directly to board).

It requires finding a supplier who has the exact or comparable part. Joe's has them although they're used but they do have long lives.
