This review is from: Logitech Li-ion Battery for Harmony One Remote 880 890 720 900 (LATEST VERSION)) (Electronics)
It looks exactly like the original one I replaced in my harmony remote. I needed to discard the original battery because it swelled so much that it was deforming the battery compartment cover. The battery came promptly and I am happy.
