A 12 second loop following one battery pack after a flight. The pack drops in warm at the first station, Inspect, where a magnifier checks it. A pack that passes moves on an arc to Cool, where its warm tint and a thermometer fall, then to Charge, where a compatible charger with a supervising eye fills a charge bar, then to Store, where its terminals are capped and it goes into a case. Each station gets a tick as it is completed. With the swollen pack selected, the pack puffs up at Inspect, gets a red cross and drops into Quarantine instead, and the other stations are skipped. The still frame shows the good pack stored.
