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.















[size=+3]Conclusion[/size]

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.



[size=+3]Notes and links[/size]

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

Another great review, thank you. If I can make a request for your reviews. Could you possibly list good sources of where to buy the item you review at a good price. Or at least where you got it.

Where to buy an items, often varies with your location, there is also the problem with CPF, they do not like that kind of info in reviews, it is for the market place.

But I do always specify where I get the batteries, look for the supplier field in the info box (Because Sibeile send the batteries to me, I list them, but when I buy batteries you will find shop name and often a SKU in that box).
