If those CR2477s have similar current capabilities as a CR2450 then a single one probably wont work - see my attempts with CR2450s here and here.

And those button cells are quite expensive. If its small size you need what about a single AAA with a boost convertor to get 3.3v? Or a small LIPO like these 240mAh ones. Thats similar in size to an ESP-07 and should last a good few hours depending on the WiFi use.

Thanks! Is there a user-friendly way to charge such LIPO batteries? And about the coin cells - looks like it's a good idea to use 2 500-600 mAh connected in parallel. But in your case ESP8266 was sleeping most of the time. Does it mean that if you send 1 request on average every minute - they will die in 72 minutes?
