[size=+3]Sanyo UR18650SA 1200mAh (Red)[/size]
Official specifications:
A old fairly high current cell with low capacity (Datasheet is marked 2008).
The discharge charts looks good, capacity is constant at any current and the two cells matches.
[size=+3]Conclusion[/size]
This is an older high current cell for tools, the last 10 years has improved cells significantly.
[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.
