Harmony One-880-890-900 OEM Battery
We have some OEM Logitech batteries that are the 'non-swelling' type. We use these in the shop for testing purposes, so they are not new, but they typically charge fully and hold the charge. Li-On batteries do have a shelf-life and we don't know how old these are, so we can't guarantee longevity. But, we can confidently say that these are legitimate Logitech batteries (not counterfeits) and that they will not swell like the notorious 'blue-labeled' battery. If you prefer to purchase a new battery, please review our guidance on this which will help you avoid purchasing counterfeit or incompatible batteries. Please note - we will not ship these batteries out of the United States, so please, only order if you are in the USA.
