Rated 5 out of 5 by from Good price, free shipping, works as expectedAlways concerned with no-name batteries so I prefer to purchase OEM. Easy order, quick shipping, work great! Hours on the phone per battery (bought two).

Rated 5 out of 5 by from Charged up againQuick delivery and now I have a decent battery that will last longer between charges. My previous Plantronics battery was dying during conference calls. Spent the extra money to get a real Plantronics replacement and not an after market generic brand.

Rated 5 out of 5 by from Less than a year to liveThis is my 4th replacement battery. I got a year out of the first one, but the last 2 have not faired as well. One day they just stop holding a charge. I simply am not happy with the life span of these batteries. Love the headset, but not the batteries they require.

Rated 5 out of 5 by from Replacement battery receivedThe new replacement battery works fine with my Savi 440 headset. so far so good - it's exactly like the original. I really was looking for the replacement battery with the on/off switch and couldn't tell if this was it. I ordered a new Savi 440 headset for a coworker a while back and the battery had the on/off switch. That would've been great if I could've rec'd that one. As it stand whenever I leave to transport I must to remove the battery from the headset. Otherwise I logon in the morning and the headset is dead - then I have to wait for it to recharge before I can use it. The 2 batteries now should help. The original battery is not holding the charge like it used to when it was purchased 4 or so years ago. I'm still EXTREMELY happy with my headset :)

Rated 5 out of 5 by from Replacement BatteryThe battery on my original headset went bad after two years, not holding a charge for more than 30 minutes. The new one is functioning well and back to normal use for 3-5 hours at a time.

Rated 5 out of 5 by from Works great!I use my Plantronics headset most of the day. The initial battery from a few years ago was not holding a charge very well, so I ordered this replacement battery and now it runs just like new.
