These are NOT new and are scavenged from disposable items. However they are useful and if you can solder and understand the problems of charging and caring for these they seem to work reliably. There are you-tube videos regarding their use (for example see bigclive.com). If you would like some then message me with enough details that I can satisfy myself that you know about them, how to charge them and will not cause a small fire. If you do not give me this information I will not respond as they are potentially dangerous. They are mostly 1500mAh (20400) or 550mAh (13400).
