This is a bulk pack of 10 standard-capacity 4680mAh batteries compatible with Zebra's TC53, TC58, TC73 and TC78 series rugged Android mobile computers — the same touch-computer family widely used in retail, logistics and field-service settings. Selling in a carton of 10 rather than as a single unit reflects that this is aimed at organisations managing a fleet of these devices (a warehouse, courier depot or retail chain), where batteries are typically ordered in bulk to keep spares on hand for hot-swapping and to replace batteries as they age out across a device fleet, rather than for an individual device owner buying a single spare.
