HKJ, I just compared this cell to the Keeppower IMR 2250mAh (Panasonic CGR18650CH) on your comparator and they look identical. Any thoughts?

The usual high standard review, HKJ, thanks. More useful for US members, I expect, as I’ve never seen this brand before.

My guess is that most 2250mAh batteries are based on very few actual cells and the CGR18650CH is one of the few.
