Datalogic 4420 Replacement Battery 3.7V 2400mAh Li-ion

Datalogic Powerscan 4420 — 3.7V Li-ion Replacement Battery (11-0023)

This 3.7V, 2400mAh Li-ion battery is a direct replacement for the Datalogic Powerscan 4420 handheld barcode scanner. It fits scanners used in retail, warehouse, and inventory environments where scan cycles run continuously across a full shift. OEM part numbers 11-0023 and 95ACC1302 cross-reference to this pack.

• Powerscan 4420 fit: The 4420 uses a dedicated battery bay with a three-contact interface that links the cell to the scanner's onboard BMS. Voltage must sit at 3.7V nominal — any deviation causes the scanner firmware to reject the pack at initialisation.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger draws and monitored BMS response across low, mid, and high state-of-charge. Cell voltage held stable under burst trigger loads, and the protection circuit responded correctly at both over-discharge and over-temperature thresholds.
• First-shift preparation for pick-and-pack: After installing, seat the scanner in its charging cradle and complete a full charge cycle before use. Scan-trigger inrush current peaks when the cell is near minimum charge — starting the first shift on a full cell prevents false BMS trips during the initial high-frequency scan bursts.

Cradle showing charging error after new pack installation

The Powerscan 4420 cradle reads pack status through the contact pins on the battery face. If those contacts carry oxidation, dust, or residue from the old pack, the cradle registers a communication fault and flags a charging error rather than beginning the charge cycle. This is contact resistance, not a faulty battery. Wipe the three contacts on both the battery and the cradle dock with a dry lint-free cloth, reseat the scanner firmly, and the cradle should show a normal charging indicator within a few seconds.

Scanner losing wireless connection during rapid scan bursts

The 4420 draws simultaneously from the radio transceiver and the scan trigger during high-frequency bursts. When the cell is below roughly 3.5V, that combined inrush pulls voltage down fast enough for the BMS to momentarily reduce current, which drops the radio link before the scanner can finish transmitting the read. The connection drop is not a wireless configuration issue — it is a low-cell-voltage symptom. Charge the battery to full before starting a burst-heavy scanning session and the radio stays connected through the combined draw.
