Datalogic 5-2043 Memor X Replacement Battery 3.6V 1800mAh

Datalogic Memor X3 / 5-2043 Series — 3.6V Ni-MH Replacement Battery

This is a 3.6V 1800mAh Ni-MH replacement battery for the Datalogic Memor X3 handheld barcode scanner and compatible models including the 5-2043, 5-2352, 5-2389, and EBS-16NMH. It fits the physical bay and matches the voltage rail the scanner's BMS expects. Capacity is 1800mAh (6.48Wh), sourced to match OEM spec.

• Memor X3 platform fit: The 5-2043, 5-2352, and 5-2389 all share the same battery bay geometry and 3.6V single-cell Ni-MH architecture. The BMS on these units does not require a proprietary handshake — voltage match and correct cell chemistry are what matter for the scanner to power on and hold connection.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on Memor X3 hardware. The BMS accepted the pack without error flags, and voltage held stable across sustained scan bursts combined with active wireless polling — the two highest simultaneous draws this platform sees in warehouse use.
• First-shift cradle cycle: After installing this pack, place the scanner in its cradle for a full charge cycle before deploying on the floor. The scan trigger inrush current peaks when the cell is near minimum charge. A pre-charged cell prevents false BMS trips on the first shift — particularly during rapid pick-and-pack sequences where the trigger fires repeatedly in quick succession.

Cradle showing charging error on a new pack

Datalogic cradles use contact-based charging — a thin film of oxidation or dust on the battery's gold contacts is enough to raise resistance and trigger a charging fault. This is not a battery defect. Remove the pack, wipe the contacts on both the battery and the cradle dock with a dry cloth or isopropyl alcohol, then reseat firmly. If the error clears, run a full charge cycle before returning the unit to service. Contact resistance above roughly 100mΩ is enough to cause the dock to reject the pack.

Scanner losing wireless connection during rapid scan bursts

The Memor X3 draws from the battery simultaneously for the imager, the wireless radio, and onboard processing. During rapid scan sequences, the combined inrush can pull voltage momentarily low enough for the radio module to drop its connection before recovering. This is more common with a partially depleted cell. If dropouts occur mid-shift, check the battery level indicator — if it reads below two bars, return the unit to the cradle. A fully charged cell maintains enough voltage headroom to sustain both the scan trigger and active RF transmission without sag-induced disconnects.
