Honeywell ScanPal EDA5S 3.85V Replacement Battery 3050mAh

Honeywell ScanPal EDA5S — 3.85V Li-ion Replacement Battery (50177747-001)

This 3.85V, 3050mAh Li-ion battery replaces the OEM pack in the Honeywell ScanPal EDA5S mobile computer. It fits the EDA5S directly and matches the original voltage rail and connector spec. The pack carries OEM part numbers 50177747-001 and BAT-EDA5S.

• EDA5S platform fit: The ScanPal EDA5S runs a 3.85V cell architecture tied to its BMS handshake protocol. A mismatched voltage or communication line will trigger an immediate charge refusal at the dock, so this pack is sourced to match the OEM voltage rail and connector pinout exactly.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the EDA5S platform. The BMS accepted the cell, reported state-of-charge correctly on the device status screen, and held stable voltage through repeated scan-and-transmit bursts without triggering a low-voltage cutoff.
• First-shift prep for the EDA5S: After installing this pack, seat the scanner in its charging cradle for a full charge cycle before putting it into pick-and-pack rotation. The scan trigger inrush current peaks when the cell is near minimum charge — a fully charged cell on first use prevents false BMS trips at the start of a shift.

Cradle showing a charging error on a new EDA5S pack

When the EDA5S cradle flashes a charge error on a new pack, the most common cause is contact resistance at the dock pins — not a fault in the battery itself. Dust, warehouse grime, or oxide buildup on the gold contacts blocks the low-level communication signal the charger uses to verify the pack. Wipe the battery contacts and cradle pins with a dry lint-free cloth, then reseat the device firmly. If the error clears after reseating, the pack is fine and charging will proceed normally.

EDA5S dropping wireless connection during fast scan bursts

During rapid scan sequences, the EDA5S draws simultaneously from the imager and the wireless radio — two inrush spikes overlapping in a short window. If the cell voltage sags below the BMS protection threshold under that combined load, the device cuts power momentarily to protect the cell, and the wireless stack drops its connection. This is more likely when the battery is below 30% charge. Keep the pack above that threshold during high-frequency scanning shifts and recharge before it reaches the low-battery warning.
