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.

I haven't taken it apart to replace them yet so not sure what batteries are in it. I used to use rechargeables but haven't the last couple of times as they don't last very long in comparison. Is there a type of battery I should be looking to replace them with?

We are heading into summer here. The last couple of days have probably been only 20C but some days they may have 30C temps when the door is in the sun.

Is this your charger? I didn't even realise such a thing existed, I might ask Santa for one for Christmas!

    Yes! That is what I have and I absolutely love it least fiddly charger experience ever. Just drop them in any old way and there's always charged batteries in the bottom tray. And also I used a Christmas gift card to buy it.

    But if that's overkill they make a regular sized more traditional 4 battery charger that also works with their lithium batteries. But I really am a fan of the full ostaton.

    Be warned they don't make lithium AAAs so the ones bundled are just NiMH. Only the AAs are lithium. I got the one without the screen that you linked and the freaking thing has WiFi and Bluetooth so it's now integrated into my Home Assistant instance. 😆 A battery charger.

    You can find the integration on HACS/Marketplace

    Haha that's awesome! I am totally going to investigate this a bit more, maybe I'll buy it for myself for Christmas! Unfortunately I am pretty sure the door lock takes AAA so it might not help my immediate problem if they don't do lithium AAAs.
