Elan HR30 Remote Replacement Battery 3.7V 900mAh

Elan HR30 Remote — 3.7V Li-ion Replacement Battery

This is a 3.7V 900mAh Li-ion replacement battery for the Elan HR30 Remote. The HR30 is a wireless handheld scanner used in retail, warehouse, and inventory management operations. This battery restores full function to the remote when the original cell degrades or fails.

• HR30 Remote fit: The HR30 runs a 3.7V Li-ion cell at this form factor — 64.94 x 36.70 x 6.60mm. The replacement matches that voltage rail and physical footprint. No modifications required.
• Bench tested on actual hardware: We cycled this cell through scan-trigger inrush draws combined with simultaneous wireless polling. The BMS held cutoff thresholds stable across repeated burst sequences without tripping on load spikes.
• First-shift preparation: After installing this pack, seat the HR30 in its charging cradle and run a full charge cycle before putting the device into pick-and-pack rotation. Scan-trigger inrush current peaks when the cell is near minimum charge. A fully charged cell prevents false BMS trips on the first shift.

Cradle charging error on a new pack

A charging error on the dock immediately after installing a new cell usually points to contact resistance between the pack and the cradle terminals — not a faulty battery. Dust, oxidation, or residue on the gold contacts interrupts the low-current handshake the dock uses to initiate charging. Wipe the contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the scanner firmly. The dock should recognise the pack and begin charging within 10 seconds of a solid connection.

Scanner losing wireless connection during rapid scan bursts

The HR30 draws current from the same cell for both the wireless radio and the scan trigger simultaneously. During rapid successive scans, combined inrush from both loads can cause a momentary voltage sag that drops below the radio module's minimum operating threshold. The BMS may interpret this sag as a low-cell event and throttle output, dropping the wireless link mid-session. If this happens, charge the pack to full before the next shift and avoid sustained burst scanning when the battery indicator shows below 20%.
