Buy: Plantronics 930 mAh R3 Battery Pack for Calisto 600 Series

I am the owner of a Calisto 620 which according to my Plantronics Hub the battery life is now always at 50%.  No matter how long I let the battery charge for.  It is an older model, so I thought the battery was no longer holding a charge.  I purchased this new battery and once more tried to charge my device, but to no avail.  The Plantronics Hub still reports 50%.  It will get lower to 25%, but never higher than 50%.
So either the Plantronics Hub reporting is faulty or the "new" battery I purchased is faulty.  I gave a rating of 3 stars, because I do not know which it is.  The battery arrived in tact and on time, so that was good, but that's about it.
I will say it functions fine on 50% no complaints there which is why I am not interested in purchasing a new one.
