Good Price, Solid Performance
So far the battery has performed great. I work 10 hour days and probably am on my headset at least 5 hours of that. I would recommend as of 2 weeks of use.

Great Replacement Battery for the Price
I used this to replace the factory original battery for my Plantronics headset and could not be happier. The battery came with some charge, but I let it fully charge before using it. I have been using it for 9 months and have not seen any issues so far. The battery has lasted in my headset for over 3 hours of continuous calls.

Works just like the factory part.
Keeping the headset in the charger tends to eat away at battery life if you are not using it all the time. Replacement battery is easy to install; it takes a little work to tuck all the wiring in between the battery and connector but it does fit. Headset works great now.

Quick replace, works like new
The original had gotten where it would not hold a charge. I was looking for a new hands free headset when I saw the battery replacement. The battery works great & cost much less than a new device. Win, win., as I always like the one I had which is about 8 yrs old, and now works like new again.

Works perfectly
It’s a battery. It charges and makes the headset work. That’s what it’s supposed to do. It did arrive 1 week earlier than expected!
