How to remove battery cover in Plantronics headset

I have an old Plantronics CS70 NC wireless headset. The battery is dying. When I checked the owners manual, I was shocked (Shocked, I say) to discover that the headset has to be mailed back to Plantronics to have the battery replaced. An Internet search turned up several companies that sell replacement batteries, biut none of them have instructions. The problem is that I cannot figure out how to open the battery cover. It has a little Phillips screw, which I removed, but that doesn't seem to hold the cover on. There is another round "cap" that appears to require a special tool. I've uploaded several photos: I called Plantronics. The tech told me that that unit is no longer supported and I need to upgrade to the newer model. I told him that the device works fine. It's just that the battery is dying. He was not sympathetic. I asked him if he could suggest a way that I could remove that cap. He first said that he is not allowed to give out that information and then that he does not have that information. One website said that the battery is soldered in place. This is the last Plantronics product I will ever buy. I tried grabbing the little edges with needlenose pliers and tweezers. No joy. It looks like it is threaded. I'm wondering whether I could epoxy the head of a Phillips screw to the cap and use that to unscrew it. Any better ideas? I don't care too much if I damage it. It's almost useless as it is and Plantronics will not repair it.

Thanks for the follow-up, and the photos of the battery and the hobby holding device -- I had never seen one of those.

Glad it all worked out.

Visit our video on how to replace your CS70n battery we carry these batteries in stock as well and offer a repair service to have it done. A lot of knock off batteries will work the same as a dying battery, so be careful.
