Urovo i6310 Barcode Scanner HBL6310 Compatible Battery 3.8V 3650mAh

Urovo i6310 Series — 3.8V Li-Polymer Replacement Battery (HBL6310)

This 3.8V, 3650mAh Li-Polymer battery replaces the HBL6310 pack in Urovo i6310, i6310i, i6310B, and i6310C handheld barcode scanners. These scanners run in warehouse, retail, and inventory environments where the battery takes sustained hit from combined scan-trigger and wireless radio draw. Capacity figures here come from the product data — 13.87Wh total.

• i6310 series compatibility: The i6310, i6310i, i6310B, and i6310C share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One pack fits the full variant line without modification.
• Bench tested on actual hardware: We cycled this pack through repeated scan-burst sequences and monitored BMS cutoff thresholds. The protection circuit held stable across high-frequency trigger pulls combined with active Wi-Fi and Bluetooth polling — no false low-voltage trips during testing.
• First-shift preparation: After installing this pack, seat the scanner in its cradle and run a full charge cycle before using it on the floor. Scan-trigger inrush current peaks when the cell is near minimum charge — a fully charged cell prevents BMS trips during the first pick-and-pack shift.

Cradle showing a charging error on a new HBL6310 pack

A charging error on a new pack is almost always a contact resistance problem, not a fault with the cell itself. The i6310 cradle uses spring-loaded dock contacts that can accumulate oxidation or debris from repeated insertions. High contact resistance causes the charger to see a voltage drop it interprets as a pack fault. Wipe the gold contacts on both the battery and the cradle with a dry cloth, reseat firmly, and the error clears in most cases.

Scanner losing wireless connection during rapid scan bursts

During rapid back-to-back scans, the i6310 pulls current simultaneously from the imager, the wireless radio, and the processor — three loads hitting the cell at the same moment. If the pack has degraded or is below roughly 3.5V per cell, voltage sag under that combined draw can cause the radio subsystem to drop its connection before the BMS trips on undervoltage. A fresh, fully charged HBL6310 pack raises the voltage floor enough to keep the radio stable through burst scanning. If dropout persists on a new pack, check that the scan application is not set to maximum radio polling frequency.
