I was on a flight to ZZZ. I was on a runway heading cleared to 11;000 departure clearance from ZZZ1. When I entered a OVC layer ATC was unable to receive my transmission. I was able to hear ATC and they cleared me Direct ZZZ at maintain 11;000. I squawked 7600 when I was unable to hear the ATC. I slowly lost all my electrical power. I squawked 7700 when I started losing all the electrical systems. I continued to ZZZ and circled over the airport running through checklists and notifying our dispatch of the electrical failure. I went through an emergency gear extension. We found a clear spot south of ZZZ and then started circling over the tower until we got a green light to land. I had no abnormal annunciator indications during the flight. The annunciator panel was black during cruise. When I landed and started taxing back the electrical systems started coming back online. I had a #1 DC GEN; #1 INVERTER; #1 NO FUEL XFR; #2 NO FUEL XFR; #2 INVERTER; #2 DC GEN and the Garmin 530 started powering back on.
Reporter stated that Maintenance in ZZZ performed diagnostic testing on the aircraft and found no malfunctions with this aircraft's electrical system other than the battery being discharged. Reporter stated that Maintenance replaced the battery in ZZZ. Reporter stated that the Reporter then flew the aircraft back to ZZZ1 as a maintenance ferry flight and that no electrical malfunctions were experienced on that flight.
An BE200 Pilot reported total electrical failure during flight.
