Edit: 2400mAh x 1.5V = 3600mWh.
Re: Costco deal - the AAs are fine but lithium AAAs usually have less capacity than NiMH, the circuitry to get them to work at 1.5V takes up too much room in the AAA form factor.

USB-C to USB-C chargers (PD) stay at 0V until the device tells them to turn on. Devices without 5.1k Ohm resistors on their Configuration Channel (CC) pins cannot initiate this, causing the charger to remain off as the charger doesn't even "know" that's its plugged into anything.
This is the case on many cheaper devices with usb c, for example the R36s and many other Retro handhelds that were posted here on SD only charge with USB-A to USB-C cables.
I did with a different brand. Unfortunately they did not last 3 months before I got a low battery warning.
My Blinks with the lithium batteries have all gone at least 2 years. Even the front door where Amazon and solicitors trigger them every other day lasted 2 years.
My 2 cents is to stick with lithium non rechargeable.
The $9.49 ones I posted earlier for the 8 pack are listed as 2500mWh and have gotten 1500-1600mah on discharge tests at 300ma/100ma respectively.
Thanks for sharing!

At $9.49, I wouldn't necessarily call the 8 pack a deal though, since they've been that price for months now so its become the regular price. That being said, I would certainly buy more if I needed them especially over a more expensive 4 pack.
2,400mAh means if you discharge it at 2,400 mA it will last 1 hour. In reality it's less, because the rating is provided under much smaller discharge current, but that's the gist of it. 1.5V is the voltage it produces. Note that for many of these batteries it will not be 1.5V for the whole discharge cycle. Rather, it will drop abruptly to a significantly lower voltage (1V or so) well before the 2,400 mAh are used.
it is scam
it is scam
Real world discharge @ 1A is about ~1600mAh. So about the same capacity as AA NiMH, but at constant ~1.5V
