I don't think there's much doubt that the little disk is an RFID, but I still don't understand what's going on with this thing.

Speculation: The device this attaches to keeps track of the battery, identifying it by its RFID tag, and ceases to accept that tag after so many hours of service or whatever it logs. Both the battery and the tag may be fine, but the device won't use it. Inkjet printer cartridges use a similar trick to discourage refilling. With those, you have to use a little reset device to trick the cartridge into thinking it's new again.

Any way the laryngoscope might be 'reset' somehow? A firmware upgrade or something like that?
Please sir
How can you reset the battary after replacement process
