AUTO-ID ASIA Barcode Scanner Replacement Battery 3.7V 1800mAh

AUTO-ID ASIA — 3.7V Li-ion Replacement Battery

This 3.7V 1800mAh (6.66Wh) lithium-ion cell is a direct replacement for the AUTO-ID ASIA barcode scanner. It fits handheld scanners used in retail, warehousing, and inventory management. Swap it in when the original cell can no longer hold enough charge to complete a shift.

• AUTO-ID ASIA scanner fit: The ASIA model runs a 3.7V single-cell architecture with a form factor of 55 × 35 × 11mm. This pack matches that envelope and voltage rail, so the scanner's power management circuit sees no unexpected signal at startup.
• Bench tested on actual hardware: We cycled this pack through repeated scan-burst loads and monitored BMS cutoff thresholds. The cell held voltage above the scanner's minimum operating point across the draw profile without triggering a false low-battery shutdown.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before putting it on the floor. Scan trigger inrush current peaks when the cell is near minimum, and a fully charged pack prevents false BMS trips during the first pick-and-pack shift.

Cradle showing a charging error on a new pack

A charging error on a freshly installed battery usually points to contact resistance at the dock, not a faulty cell. Cradle contacts collect dust, label residue, and skin oil from repeated insertions. High resistance between the dock and the pack's gold contacts causes the charger circuit to see an out-of-range response and flag an error. Wipe both the pack contacts and the cradle pins with a dry cloth, reseat the scanner firmly, and check whether the error clears within 30 seconds.

Scanner losing wireless connection during a rapid scan burst

During a fast scan burst, the imager draw and the wireless radio transmit pulse happen almost simultaneously. On a degraded or low cell, this combined inrush pulls the pack voltage below the radio module's minimum threshold — typically around 3.2V — causing the wireless stack to drop. The scanner may reconnect on its own, but the session data can be lost. Keeping the cell above 3.5V before a high-frequency scanning session avoids the sag that triggers this dropout.
