The rated current is low for a IMR cell, and the actual test confirms that the cell cannot deliver high current.

The cell does very well up to 2A, but the tracking between the cells is not perfect.

Conclusion

This cell has better than rated capacity, the current capability is fine for a ICR cell, but low for an IMR cell.
I will rate it as a acceptable cell.



Notes and links

According to Sibeile the IMR text will be removed from the next batch of cell.

Thanks for this first Sibeille review. It solves the yes or no IMR mystery if even the factory (is it a factory or a rebranding firm?) is leaving the IMR claim. Pity though, I would not have minded a new source for IMR batteries.

Ah, missed that one, thanks. Their batteries at least appear to be consistant in not being IMR..

Seems like Sibeile just smacks an IMR label on just about any battery.
