  Wow, I actually get a whole bunch of new devices...

  I put circuit python on a RPi Pico, and then using the HID library I got it to pretend to be a mouse when plugged into a computer.

  But when it's plugged into a computer, it also appears as a mass storage device (that's how you update the python code).

  So how is it appearing at two devices? I assumed it was setting up a virtual USB hub and "attaching" two devices to it, but that doesn't seem the be the case. When I run lsusb I only see one device. I'm so confused

  Ah yeah, I don't really count those because they include a battery management system - they aren't just a cell. But you're right. It's an AA lithium-ion.

  That's a good one.

  I used it to write Christmas cards. I'm always so bad at those.

  The fact the batteries can run down to zero isn't the issue

  Yeah, I only mentioned that to explain why you won't find lithium-ion chemistries in AA, AAA, etc., batteries.

  Your quora link was great btw. That might be the first time I've seen useful information on that site.

  Those are lithium-ion batteries (like in your phone, laptop or drone), and you'll never find an AA or AAA with a lithium-ion chemistry because the devices that use AA & AAA don't contain the under volt protection that li-ion batteries require. (If you run a li-ion battery flat, you've essentially destroyed it).

  Typical AA & AAA chemistries (e.g. NiMH rechargeable and alkaline non-rechargeable) can happily be run down to 0v.

  It seems very odd that @Familyman's device specifically advises against using rechargeable batteries. The device couldn't be damaged by the lower voltage of rechargeable batteries because alkaline batteries would also have those lower voltages at some point.

  I bought some off-brand batteries in bulk recently. They were a lot cheaper, and I assumed they'd be worse but at least comparable to the branded batteries. But it turns out they were a total scam, and they went flat within days (when I'd normally expect them to last a year). @Familyman maybe you just have a batch of bad batteries?

  Yes good point. I've bought a lot of IKEA rechargeables with that assumption too

  Get yourself some decent rechargeable batteries. Eneloops are good.

  But yeah, 2 days seems pretty bad. My eufy doorbell lasts months
