HitechReplacement Cordless Phone Battery for Plantronics CS50, CS55, CS60 Wireless Headset

I replaced a nonworking official battery pack which had seen a few years of use (at least) and no longer held enough charge to last through a 2 hour telephone call.This replacement seems to be doing a fine job, with the charge now lasting fine through 2 and 3 hour meetings with no problem. It wasn't too tricky to fit into the headset holder. This long capacity pack was slightly larger than the original battery and required a little fiddling to get in place (the wire coming off it is pretty short, so you might need to try putting the battery in label side down if it doesn't reach facing the other way).(I'll try to follow up in a year or two--as part of a battery is how well it lasts under ordinary use.)

I bought this battery back 6 months ago and got it on time, I installed it on my CS50 Plantronic Audio Device. It works like a charmed. That is why I bought 2 more as some of my co-workers need batteries and where I am are pretty expensive.The first time, item came on a timely manner (tracking number and all). This second time, unfortunatly (the 2 batteries) have not arrived Nov 02nd (since Oct 21st) as there was no tracking assigned to the shipment and of course got lost... I've contact the reseller on Nov 01st and they advised they will send me a new order with tracking number... I'll wait on it! I will keep an update.So far overall product is affordable and reliable! Good product

I would've given this a 5 star but like other reviews the connector doesn't fit at all! but with a pick tool (or sewing needle) you can remove the connector from the old battery and replace the on on the new battery. Take a pic first of the connector for wire orientation. Lift up on the plastic locking pin with tool or needle then remove one wire at a time. carefully do the same on the other connector. Reinsert and check that it locks. Repeat process for the other wire and wa-la! your done.

Inexpensive replacement that seems to be as good as the original. Charges quickly and I have had it in use for about 6 hrs. without getting a low battery status. It is a tight fit installing it and removing it but it will fit and it can be removed.

Slightly too big to fit easily in our Plantronics CS 50/55 wireless headsets. It takes some effort to get them crammed in, but, once done, they seem to work well.

Some reviewers wrote having trouble inserting the battery - I didn't have any problems. The fit is snug - but the packaging does have enough give - just don't be afraid to fold in the rough edges and firmly push the battery in. Also of note is the power wire on this battery is much longer than the original - just fold it into the gaps/space and then put the cover back on - it all fits in the end.Once the battery was inserted - the phone charged up and now works like new again. For the price - I bought two just in case I got a bad one. Now I've got a spare when this one goes out.

This battery charges up well and then the charge lasts a few hours. I installed it in wireless headphones and it does a terrific job. Plays music for several hours.

I've had my CS-50 headset for about six years now and the original battery no longer lasts the entire day. While my experience with this battery is limited to three days, I can say that it lasts the full ten hour day and seems to work well. Again, this is a limited time frame in which to judge a battery, but so far, so good. And for less than $5 it seems to be well worth the price. It fit perfectly, and I haven't had any of the connection/size issues that some other reviewers have had. Again, I figured that for less than $5 it was worth the risk and it's paid of so far.
