Datalogic Kyman 94ACC1302 Replacement Battery 7.4V 3400mAh

Datalogic Kyman — 7.4V Li-ion Replacement Battery (94ACC1302)

This 7.4V 3400mAh Li-ion battery replaces the original pack in the Datalogic Kyman handheld barcode scanner. It fits the Kyman series used in retail, logistics, and warehouse inventory operations. Cross-compatible OEM part numbers include 94ACC1302, 700175303, 944501055, 944501056, 944501057, 944501088, 944551004, and 944551005.

• Kyman platform fit: The Kyman series shares a common battery bay geometry, contact layout, and BMS handshake across its variants. One pack covers the full range of Kyman units — the dock, trigger circuit, and wireless radio all draw from the same 7.4V cell architecture.
• Bench tested on actual hardware: We cycled this pack through the Kyman's BMS and confirmed the protection circuit responds correctly to scan-trigger inrush and wireless radio polling load. The BMS did not trip under combined draw at any state of charge above the low-voltage cutoff threshold.
• First-shift preparation: After installing this pack, seat the Kyman in its cradle and run a full charge cycle before deploying it on the floor. Scan-trigger inrush current is highest when the cell is near minimum voltage — a fully charged pack prevents false BMS trips during the first pick-and-pack shift.

Cradle showing a charging error on a new pack

Datalogic Kyman cradles verify battery contact resistance before initiating a charge cycle. A new pack with oxidised or slightly misaligned contacts can fail that handshake and throw a charging error even though the battery itself is fine. The fix is mechanical — remove the pack, wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat firmly until you feel the latch click. If the error clears, the contact resistance dropped below the cradle's threshold and charging will proceed normally.

Scanner losing wireless connection during rapid scan bursts

During a rapid scan burst, the Kyman fires the imager and maintains a wireless radio link simultaneously — both draw current at the same moment. On a depleted or degraded cell, this combined inrush can cause a brief voltage sag that drops the radio below its minimum operating threshold, cutting the wireless connection mid-session. This is not a firmware or network issue — it is a voltage delivery problem at the cell level. Confirm the pack is above 7.0V under load before the shift starts; if the sag persists on a fresh charge, the cell capacity has degraded and the pack needs replacing.
