Elan HR30 Remote Compatible Battery 3.7V 1800mAh Li-ion

Elan HR30 Remote — 3.7V Li-ion Replacement Battery

This 3.7V, 1800mAh Li-ion cell replaces the original battery in the Elan HR30 Remote barcode scanner. It fits the handheld unit used in retail, warehouse, and inventory management workflows. No OEM part number is published for this pack — match by fit model before ordering.

• HR30 Remote platform fit: The HR30 Remote draws from a single-cell 3.7V rail shared across its laser or imager module and wireless radio. Both systems pull from the same pack simultaneously during a scan burst, so the cell must handle combined inrush without triggering a BMS undervoltage cutoff.
• Bench tested on actual hardware: We cycled this pack through repeated scan-burst sequences and monitored BMS response under combined radio and imager load. Voltage held stable above the cutoff threshold across the test window, and the protection circuit recovered cleanly after simulated deep-discharge events.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before starting pick-and-pack. Scan trigger inrush peaks when the cell is near minimum voltage — a fully charged pack prevents false BMS trips on the first trigger pull of a shift.

Cradle showing a charging error on a new pack

Charging docks on the HR30 Remote sense current flow through the pack's contact pads. If the contacts on the replacement cell or the cradle bay have residue or oxidation, the dock reads a high-resistance connection and flags a charging fault rather than beginning a charge cycle. Wipe both the pack contacts and the cradle pins with a dry cloth, then reseat the scanner firmly until the dock clicks into position. If the error clears, the contact surface was the problem — not the cell or the dock electronics.

Scanner losing wireless connection mid scan burst

During a rapid scan sequence, the HR30 Remote fires the imager and transmits the decoded data over its wireless link at the same instant. That combined draw — imager plus radio — creates a short inrush spike that can sag cell voltage below the BMS cutoff if the pack is below roughly 3.2V. The scanner drops its wireless session to protect the cell, then reconnects once voltage recovers. Keep the pack above 20% charge during high-frequency scanning runs to stay clear of that sag threshold.
