Narrative:

Upon arriving at XXX, it was discovered that a battery had been loaded onto my aircraft. The labeling of the battery indicated that this was a 12 volt automotive battery. The battery was tagged as a piece of checked baggage. The battery was not in a battery box nor was it carried as part of a wheelchair. Further, no mention of the battery was made on the manifest. At no time prior to arriving at XXX was the crew made aware that we were carrying this hazmat. The owner of the battery was not even on my flight. The owner had actually arrived at XXX the day before and made a claim for the lost battery. On the claim itself he described his lost bag as a 'boat battery!' from the ticket agent in ZZZ to all the rampers who handled the battery, I'm stunned that nobody refused this shipment.
