Rated 5 out of 5 by from Impossible to replace batteryI didn't want to have to invest in another headset from Plantronics, so at their suggestion, I purchased this little battery. It is impossible to plug in to the headset because it's so small and fits way too tight. The directions provided are brief and not a lot of help. It would be nice if the pieces really fit together. I'm looking for another headset, but I will go to another manufacturer. Sorry, Plantronics.

Rated 5 out of 5 by from Back to its old self!I have had my Plantronics headset for ~5 years and was having some random issues that I finally decided was related to its ability to hold a charge. Didn't want to give up my current headset because I seemed to have better call clarity and MUCH better tech support than any of my co-workers. Ordered a new battery and am I pleased to be back in business. Once ever 5 years, I will gladly pay to replace the battery. Thanks for making such a high quality headset, you have earned a loyal customer and a lot of recommendations to my co-workers!

Rated 5 out of 5 by from Works GreatI recently purchased the replacement battery for our CS50. My old battery would not hold a charge for more than an hour.  The new battery has greatly increased that.
