I replaced them in April. Should have had another 6 months or more but instead the charge is now at 1%... previous batteries lasted almost 18 months.

No particularly interesting history. Automations locked or unlocked it about 6 times over that 2 day period.

Not a question, just a frustration.

Home Assistant graph showing the day and time along the bottm (about 12 noon on 10 November to 12 noon 12 November) and the graph shows a line largly straight going from 50% to 1% over this two day period.

Either your current batteries are a worse brand the last one, or your hardware has developed a problem. The strong loss within a few days points into that direction. Condensate, maybe?

    I'll probably replace the batteries and see if it happens again. It's a bit humid but not cold here as we head into summer, so maybe?

    Depending on how the batteries are mounted you could probably make a usb battery shim with a long enough cable, some planning and then never ever having to think about it again

    I don't think there's a way to do that without making it look odd! I have a home assistant notification when the batteries get low, and they normally last over a year, so I'm happy to just change them as needed 🙂
