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.


For its time an impressive tool cell, but the capacity is low by today's standard.

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
