My batteries came on time and I soldered them into my bluetooth speaker. Took a few hours for a full charge. Now the capacity is almost 24 hours at 1/3 volume . Up from 8-10 with original batteries. The original batteries were generic with the blue wrap just like these and they lasted 5 years. I had bought these other ones with the green label claiming really high amp hours, and they petered out after a few months , and had actually less capacity than the original batteries. Don't buy those , green label called SKY something or other, total crap . So far so good , and I would definitely go with any of the generic batteries with the blue wrap over most of the others with flashy names and unrealistic claims .

Got these for a vape. They hold a charge well, and drain slowly (as opposed to some which suddenly drop off after like 75-50%).

I got this because one of my solar lights was not working. The battery came with charge and my light works now!

maybe I did a bad soldering job, or maybe I got a bad batch, but using these to power my small meshtastic device and on full charge, it only lasts a few days when other 950mah (2000mah less than one of these batteries alone) can keep the device on for weeks. that's a pretty concerning ratio.
