EasyPack EZPack XL Barcode Scanner 3.7V 1800mAh Compatible Battery

EasyPack EZPack XL / Poliflex 750 — 3.7V Li-ion Replacement Battery (56446 702 099)

This 3.7V 1800mAh Li-ion battery replaces the original pack in the EasyPack EZPack XL and Poliflex 750 barcode scanners. It matches the OEM voltage rail and connector format for both models. Capacity is 1800mAh (6.66Wh), sourced against part numbers 56446 702 099 and 251802-62.

• EZPack XL and Poliflex 750 compatibility: Both scanners share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol — which is why one pack covers both. The fuel gauge data line communicates remaining capacity to the host device identically on each platform.
• Bench tested on actual hardware: We cycled this pack through simulated scan-burst loads — alternating laser trigger pulses and wireless polling intervals. The BMS held cutoff thresholds correctly and the protection circuit tripped cleanly at the expected low-voltage floor without false positives during inrush.
• First-shift preparation for pick-and-pack environments: After installing this pack, seat the scanner in its charging cradle and run a complete charge cycle before the shift starts. Scan trigger inrush current is highest when the cell is near minimum voltage — a fully charged cell prevents the BMS from tripping on the first heavy burst of the day.

Cradle showing a charging error on a new pack

Charging docks on the EZPack XL and Poliflex 750 read contact resistance as part of the charge initiation handshake. A new pack with oxidised or contaminated contacts can register above the dock's acceptance threshold, triggering an error before any current flows. Wipe the gold contacts on both the battery and the dock slot with a dry lint-free cloth, then reseat firmly. If the error clears, run the full charge cycle before pulling the scanner for use.

Scanner losing wireless connection during rapid scan bursts

During a fast scan sequence, the radio transmitter and the scan trigger fire almost simultaneously, creating a combined inrush spike that a degraded or low cell struggles to supply without voltage sag. When cell voltage dips below the radio module's minimum operating threshold mid-burst, the wireless link drops — often without any low-battery indicator showing on screen. This is not a radio fault; it is the battery failing to hold voltage under stacked load. Charge the pack fully before the shift and confirm resting open-circuit voltage reads at least 3.9V before docking the scanner for use.
