Do We sell a battery for the CS510 and CS520?

Answer: Nope!

This battery comes with a special tool to help Customers get the battery in and out of the headset a bit more easily.

WE DO NOT CARRY IT BUT WE CAN SPECIAL ORDER IT. THE ETA IS 7-10 DAYS.

Part # 202599-03

However, your Customer needs a battery a lot sooner, you can order a geniune Plantronics battery that will be thin enough to fit into their headset. It just won’t come with the special tool.

The part number for this beauty is: 65358-01!

We usually have this in stock, but sometimes they run out, so check with Shipping to see if these are in before promising a time for your Customer.
