Question: Will this battery be the correct battery for the Harmony One?
Document: I thought my 4 year old Harmony One had bit the dust. It would occasionally re-set itself; would constantly lose the correct time and would not hold a charge for more than 2 or so days. I bought this replacement battery and the Harmony One is like brand new! Keeps perfect time; lasts 4-5 days without a charge. Great price, great, quick service/delivery. Very good purchase.
Correct product, arrived quickly and worked as described. I'll certainly order the same ones again when I need to replace them in the future.
This is the exact same battery that came in my Harmony One remote. No issues with it. Works as it should.
I know the battery was the correct replacement but it did not work, nor accept a charge. When I took out of the package the appearance of the battery appeared rounded or swelled in the middle hence, I don't know if that was the problem or not. I received a full credit back from Amazon due to his being defective. Thanks Amazon!
This is the exact replacement for my Harmony one and it works great after replacing the battery and giving it a full charge.
This is the one that you need for your harmony. Don't be surprised when your old one is hard to pry out. They swell. But this is a great battery after almost 6 months of use.
Installed battery and got error message (contact customer support) from remote when installed in cradle,. Would not recommend for Harmony One
This battery has been working well and holding a good charge in our Harmony One remote for a few weeks now. Would recommend to anyone needing a replacement battery.
Although It was listed as the correct replacement, it would not charge. I kept getting an error. I went directly to the Logitech site and ordered it from them, twice the price; but worked.
Gave my harmony one new life!I can finally go a few days without charging my remote! It was getting so annoying! Wasn't willing to drop $350 on a new harmony remote!Thanks for finally supplying a spare battery logitech!!! !
Answer: Yes it us. That's what I used it in.
