HL18650V Cold-Storage Scanner Battery Pack
Project Challenge
Handheld barcode scanners in cold-chain warehouses must keep working throughout long shifts in refrigerated and frozen storage areas. Low temperatures can reduce the available capacity of a conventional scanner battery, while voltage drops may interrupt barcode scanning and inventory updates. The battery pack also needs to fit the limited space inside a handheld device.
UltraXel Solution
UltraXel designed a compact 1S1P cold-storage scanner battery pack using the HL18650V low temperature 18650 battery cell. With 3.6V nominal voltage and 2.9Ah capacity, this cold weather 18650 battery configuration is intended to support handheld scanning in refrigerated warehouses. The pack design can be adapted to the scanner’s space and connector requirements, with operating performance verified in the final device.
