[size=+3]Samsung INR18650-15M 1500mAh (Cyan)[/size]
Official specifications:
This is a fairly old high current battery (Datasheet from 2010)
The discharge curves match very well and the capacity is just about constant at any discharge current below rating.
[size=+3]Conclusion[/size]
For its time an impressive tool cell, but the capacity is low by today's standard.
[size=+3]Notes and links[/size]
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
