Review: Works great - Bought to replace a Harmony One swollen battery, which seems to be a common issue. I've used this battery for a month now and so far no issues, in fact is seems to last longer than the previous battery (Which is probably due to a defective battery). 10/22/13 Update to my review, I felt compelled to write a follow up since I've seen so many negative reviews. I've used this battery for almost 3 years now with no issues and am really surprised on how many people had defective batteries. Maybe I've been lucky but I've noticed I can't go more than a couple of days on a single Charge (Which happens due to aging battery) but that's been OK since we put the remote back on the charger by the end of the day. I haven't had a problem with the stock charger charging the battery nor have I had the pleasure of this battery failing.
Review: Perfect for Logitech - Had a Logitech Harmony all in one remote. Sadly they have stopped producing them. Ours was acting strange rebooting not turning on devices. Replaced the original battery with this one and it’s good as new.

### ⭐⭐⭐ AEC Review
*by A***N on August 16, 2012*

The rechargeable battery worked great upon arrival when I installed the unit. Now I need to purchase a new battery, because for some reason the battery wil not hold a charge long. Amazon's service was good, however; the suppliers service/product was not to good, for me.
