Motorola 21-62606-01 Barcode Scanner Replacement Battery 3.7V 3400mAh

Motorola (21-62606-01) — 3.7V Li-ion Replacement Battery

This is a 3.7V, 3400mAh Li-ion battery built to the OEM part number 21-62606-01. It fits Motorola handheld barcode scanners used in retail, warehousing, and logistics environments. Swap it in when the original cell no longer holds charge through a full shift.

• Motorola 21-62606-01 platform fit: Scanners sharing this part number run on a single 3.7V Li-ion cell with a common connector footprint and BMS handshake. The dock and scanner firmware both verify cell ID at charge initialisation — this pack passes that check without modification.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the bench, confirmed BMS cutoff triggers at the correct low-voltage threshold, and verified the charging dock accepted the pack without throwing a fault code on the first seat.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan trigger inrush is highest when the cell sits near minimum — a fully charged pack prevents false BMS trips on that first burst of scans.

Charging docks on Motorola handheld scanners read contact resistance at the battery terminals before starting a charge cycle. If resistance is too high — typically from oxidation or debris on the gold contacts — the dock throws a fault rather than charge. Wipe the battery contact pads and the cradle contacts with a dry lint-free cloth, then reseat the scanner firmly. A successful charge cycle should begin within 10 seconds of correct seating.

Scanner dropping wireless connection during rapid scan bursts

A fast scan burst fires both the imager and the radio transmitter at nearly the same moment. That combined inrush draws a short but sharp current spike from the cell. If the pack voltage sags below the radio module's minimum operating threshold during that spike, the wireless link drops before it can transmit the last scan. This is most likely on a cell below 3.5V — keep the battery above that point by returning the scanner to the cradle between picking runs.
