I bought these July 2025 for $13 and they are still going strong. I have another similar style and haven't tried to cross the batteries/chargers, but this one definitely lasts longer than the other. I just use these for blink cameras and charge them at 5V-1A (pretty sure that is what the manual called for and made me question the charge rate claim) while I think the other called for 3A, all my generic batteries I'd rather do at 1A while I'm at home and aware of it charging just in case
I use similar (1.5V Lithium) batteries in my Quest controllers. When I get a low-battery warning for my controller, I have about 10 minutes left due to their steep voltage drop-off.
For this SD, the price is good but the capacity is lacking...

this is like saying i have 80 in my pocket and you have 100 in your pocket.. expect you have 100 pesos and i got 80 dollars.. unit matters, and matters a lot.
a 1.5v Li battery can certainly be discharged at 1.2V with buck converter and it can providing a much higher current drawing at 1.2V. if you try to discharge a 1.2 battery at 1.5v (with things like boost converter, your will get much less current draw. AH comparison only make sense with the voltage fixed. it is completely meaningless with voltage is not fixed. otherwise you can claim two or three of you enloop somehow is much bigger than battery found on the macbook...
Using these to power onn LED strips with USB packs for glow disc golf.
