Honeywell ScanPal EDA70 Replacement Battery 3.78V 8850mAh

Honeywell ScanPal EDA70 / EDA71 — 3.78V Li-ion Replacement Battery (50141821-001)

This 3.78V Li-ion battery carries OEM part number 50141821-001 and fits the Honeywell ScanPal EDA70 and EDA71 rugged mobile computers. It runs at 8850mAh (33.45Wh) and slots into the same bay as the original pack. Both scanner models share the same battery connector, voltage rail, and BMS handshake protocol.

• EDA70 and EDA71 compatibility: Honeywell built the EDA70 and EDA71 on the same hardware platform — identical battery bay geometry, the same 3.78V nominal rail, and a shared BMS communication line. One pack covers both units without modification.
• Bench tested on actual hardware: We cycled this pack through repeated scan-trigger bursts and active Wi-Fi polling sessions. The BMS held voltage within spec across burst draws and did not trigger a false low-battery cutoff during back-to-back scan cycles.
• Cradle charge before first shift: After installing this pack, seat the EDA70 or EDA71 in its charging cradle and let it complete a full charge cycle before use. The scan trigger inrush current peaks highest when the cell sits near minimum — a fully charged cell prevents the BMS from tripping on the first pick-and-pack run of the shift.

The EDA70 charging cradle communicates with the pack over a data contact separate from the power pins. If that contact is dirty or the pack is not fully seated, the cradle throws a charging fault even though nothing is actually wrong with the battery. Remove the pack, wipe the gold contact strips on both the pack and the cradle bay with a dry lint-free cloth, then reseat the pack with firm downward pressure until the latch clicks. The fault clears once contact resistance drops below the cradle's detection threshold.

Scanner losing Wi-Fi mid-session during rapid scan bursts

The EDA70 runs its 802.11 radio and the scan imager simultaneously during active picking. Each scan trigger pulls a short inrush current on top of the sustained radio draw — if the cell voltage sags under the combined load, the radio subsystem drops its association before the BMS trips the full device. This shows up as a Wi-Fi disconnect during fast scan runs rather than a full shutdown. A cell that has aged or discharged below 3.5V sags further under dual load. Charge the pack to at least 3.8V before the shift and the voltage headroom keeps both subsystems stable through burst scanning.
