Narrative: My flight began at ZZZ1 with the intent to fly direct to ZZZ for touch and goes and return to ZZZ1. I have flown this particular airplane multiple times with no issues. The start; taxi; and run-up were normal and no different than any other time; except that the strobe lights were blinking slower than usual but working as expected.The airplane was flown earlier; and no issues were reported; hence there was no reason to suspect a problem. I did two take-offs and landings before departing to ZZZ; I had no issues. During a normal approach to landing at ZZZ; all-electric equipment failed at an altitude of 300 feet from touching down on Runway XX. I was forced to immediately clear the runway and exit onto the first taxiway I saw; Taxiway XX; I had a disabled radio; transponder; and ADS-B.Although clear from the tower for a touch and go; I could not continue the flight safely with disabled equipment; therefore a go-around was not an option. Luckily; I have a handheld radio and was able to contact the control tower to explain what happened; and request directions to the parking area. I had to deviate from the touch and go clearance since I dint know what else was wrong with the airplane and continuing the flight would have been unwise.After arriving at the parking area; I talked to the mechanic who was only available by phone and asked me to go through my checklist again to troubleshoot the issue. I made multiple attempts to restart the airplane; loud cabin speaker noises could be heard as the power switch was turned on as if there was a short circuit in the system; but all fuses were okay and there was no power to start the engine. The mechanic determined that I had a dead battery and it could only mean that the airplane suffered an alternator failure on landing; grounding the airplane immediately.The flight club from which I rented the airplane has multiple airplanes of the same make and model and provided me with one so I could fly back to ZZZ1. The return flight was uneventful.




Synopsis: PA28 pilot reported that on final approach all electrical equipment failed. After a successful landing; it was determined that the battery was dead.
