Does this use aaa or aa battery or a built in rechargeable battery?

Hi Pencil, Logitech Signature M650 Wireless Mouse includes AA battery.

Can i use the existing unified receiver with this mouse?

Hi Schira, The mouse can be connected via Bluetooth Low Energy or Logi Bolt USB receiver only.

will two logitech wireless mice interfere with one another in the same workspace, ie. one for a laptop and one for a workstation pc?

I don't believe they would as each one's dongle is inserted into a different computer. Now, as far as bluetooth is concerned, I would imagine they wouldn't so long as each computer is made to only connect with one and not the other. As for myself, I do have a Logitech M650 with it's dongle plugged into my Windows laptop and a Logitech M525 with it's dongle plugged into my Chromebook and have never had any problems with one interfering with the other when both computers and mice were turned on and being used at the same time. Hope this helps!
