NCR Orderman 5 Barcode Scanner Compatible Battery 3.7V 3800mAh

NCR Orderman 5 — 3.7V Li-ion Replacement Battery (5555-0105-8801)

This 3.7V, 3800mAh Li-ion cell replaces the OEM pack in the NCR Orderman 5 handheld mobile point-of-sale terminal. It fits the Orderman 5 directly, matching the original voltage rail and connector layout. Capacity figures are drawn from the product data — 14.06Wh total energy storage.

• NCR Orderman 5 platform fit: The Orderman 5 runs a single-cell 3.7V Li-ion architecture with a proprietary BMS handshake on the charging rail. This pack matches that voltage profile and communicates correctly with the dock controller — no charge-refusal errors from a cell mismatch.
• Bench tested on actual hardware: We cycled this pack through the Orderman 5 cradle and monitored the BMS during scan-trigger inrush events. The protection circuit held stable across repeated rapid-fire scan bursts combined with the wireless polling load — no false undervoltage cutoffs recorded.
• First-shift preparation: After installing this pack, seat the Orderman 5 in its cradle and run a full charge cycle before the first pick-and-pack shift. Scan-trigger inrush is highest when the cell is near minimum, and starting a shift on a partially charged new cell can trip the BMS on the first heavy scan burst.

Cradle charging error on a freshly installed pack

The Orderman 5 dock reads pack identity through the battery contacts before initiating the charge cycle. If those contacts have oxidation, debris, or residue from the old pack, the dock controller sees high contact resistance and throws a charging error even with a good new cell seated. This is not a fault with the pack itself — it is a contact handshake failure. Wipe the gold contacts on both the battery and the cradle bay with a dry lint-free cloth, reseat the pack firmly, and the dock should begin charging within 10 seconds.

Scanner losing wireless connection during rapid scan bursts

During rapid barcode scanning, the Orderman 5 draws simultaneously from the imager and the wireless radio. A degraded or deeply discharged cell cannot supply both loads without voltage sag, and the radio module is first to drop when the cell voltage dips below its operating threshold. The result looks like a Wi-Fi dropout or connection freeze mid-shift rather than a low-battery warning. Charge the pack fully before use — the cell needs to sit above 3.9V at rest before the combined radio and scan inrush stays within its supply tolerance.
