This is a little protective battery clip for the NP-FW50 series of batteries from Sony, used in cameras like the a6500. It has a Full/Empty indicator - you simply load the battery with the arrow facing to what it is, Full or Empty. This will allow you to quickly check to see if the battery you're about to grab is ready to use or ready to charge.
