Better than a replacement, clear progress

Logitech has had to sell a bad series of batteries on the Harmony One, because many of us have had the same unpleasant experience: the original battery that swells (which is very difficult to remove) and a heavy loss of autonomy (the remote takes only the evening).

Fortunately, this replacement battery works perfectly despite its low cost. I use it quite extensively for over a year, she not only did not swell, but I have seen no loss of autonomy. Very often I do not recharge it for over a week and I've never been caught short.
Highly recommended!
