Honeywell Voice A700x Replacement Battery 3.7V 6600mAh

Honeywell Voice A700x / Voice A700 — 3.7V Li-ion Replacement Battery

This is a 3.7V, 6600mAh Li-ion battery for the Honeywell Voice A700x and Voice A700 mobile computers. These handheld devices run voice-directed work and barcode scanning in warehouse and logistics environments. The pack slots into the same battery compartment as the original and connects through the same dock charging contacts.

• Voice A700x and A700 compatibility: Both models use the same 3.7V single-cell Li-ion architecture and share the same battery bay dimensions and contact layout. The BMS handshake is identical across the two, so one pack covers both without any firmware or connector difference.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Voice A700x platform. The BMS responded correctly to the cradle charge signal, balanced the cell to 4.2V at full charge, and tripped the under-voltage cutoff at the expected threshold during deep discharge simulation.
• First-shift cradle protocol: After installing this pack, place the scanner in its cradle and complete a full charge cycle before use. The scan trigger inrush current is highest when the cell sits near minimum. A fully charged cell prevents false BMS trips on the first pick-and-pack shift.

Cradle showing a charging error on a new pack

A charging fault on a brand-new pack is almost always a contact resistance issue, not a cell problem. The Voice A700x cradle uses spring-loaded gold contacts, and oxidation or debris on either the dock or the battery contact pads raises resistance above the threshold the charger circuit tolerates. Wipe the three contacts on the battery base and the corresponding cradle pins with a dry lint-free cloth, then reseat the pack firmly. If the error clears, the cell was fine — the contact was the issue.

Scanner losing wireless connection during rapid scan bursts

During a fast scan sequence, the imager and the wireless radio fire simultaneously, creating a combined inrush current spike. If the cell voltage sags below the radio module's minimum during that spike, the wireless link drops before the BMS trips. This is more common at the end of a shift when cell voltage is already low, or on a degraded original battery where internal resistance has climbed. Swap to a fresh, fully charged pack and run the same scan sequence — if the drops stop, voltage sag was the cause, not the radio hardware.
