Datalogic SP5600 Barcode Scanner Replacement Battery 3.7V 1800mAh

Datalogic SP5600 Datacollector — 3.7V Li-ion Replacement Battery

This is a 3.7V 1800mAh Li-ion battery for the Datalogic SP5600 and SP5600 Datacollector handheld barcode scanner. It replaces the original cell when capacity fades and the scanner can no longer hold a charge through a full shift. Voltage and capacity match the original pack exactly.

• SP5600 and SP5600 Datacollector compatibility: Both models run the same 3.7V single-cell architecture with the same connector pinout and BMS handshake. One battery fits both variants without modification.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger and wireless radio draw. The BMS responded correctly to inrush spikes at low state of charge and did not trip into protection mode under normal operating loads.
• First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before putting it into pick-and-pack rotation. Scan-trigger inrush current is highest when the cell sits near minimum, and a fully charged pack prevents false BMS trips on the first shift.

Cradle showing a charging error on a new pack

The SP5600 cradle reads battery state through the dock contacts on the base of the scanner. If those contacts carry oxidation or debris from a worn-out pack, the cradle throws a charging fault even though the new battery is fine. Wipe the gold contacts on both the battery and the cradle with a dry cloth, then firmly reseat the scanner. The charging indicator should turn solid within 30 seconds of a clean connection.

Scanner losing wireless connection during rapid scan bursts

Back-to-back scanning in a busy pick line puts simultaneous load on the imager and the wireless radio. At high burst rates, combined inrush can momentarily sag the cell voltage below the radio module's minimum operating threshold, dropping the connection. This is more common when the battery is below 20% charge. Keep the pack above that level during intensive runs, and if dropouts persist, check that the wireless polling interval in the SP5600 configuration is not set to its shortest value.
