This is a high capacity cell from 2012 where it was rated 2900mA, in 2014 the rating was changed to 2850mAh and model name changed from ICR to IMR.

The discharge curves matches very well, but the battery is not good at high current.

[size=+3]Conclusion[/size]

This is a good battery, but capacity and current handling cannot match the last generation cells.
