Narrative:

Due to battery failure; I lost all electronics; radios; egt monitor; and gear operation failure upon take off/climb when I retracted the landing gear with the gear lever. I initially squawked 7500 in error before correcting squawk to 7600. I was finally able to get partial (very intermittent) communications with ATC on my second radio. ATC cleared me to return and land. On my initial return to airport; the gear was not down so I executed a go-around in order to manually pump the gear down in to place. Then; I returned to the airport and safely landed. Upon safely landing; I taxied to [FBO]; called FSS to close my flight plan; and then called the tower. [Maintenance shop] on the field diagnosed that it was a bad battery and made the necessary repairs.
