LXE MX7 Barcode Scanner Compatible Battery 7.4V 3400mAh

LXE MX7 — 7.4V Li-ion Replacement Battery (159904-0001)

This 7.4V 3400mAh Li-ion battery replaces the original pack in the LXE MX7 rugged handheld terminal. The MX7 is a data collection device used across warehouse, retail, and logistics environments for barcode scanning and asset tracking. Voltage, capacity, and connector match the OEM specification.

• MX7 platform compatibility: The MX7 series uses a shared battery bay and BMS handshake across its variants. OEM part numbers 159904-0001, 163467-0001, MX7A380BATT, MX7382BATT, MX7392BATT, MX7394BATT, and 161772-0001 all cross to this pack. The connector orientation and cell voltage profile match what the MX7 host controller expects on power-on.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on the MX7 platform. The BMS responded correctly to the host handshake, accepted charge from the standard LXE cradle, and held voltage within spec across the discharge curve. No protection circuit trips were recorded under normal scan-and-transmit load.
• First-shift prep for pick-and-pack operations: Seat the new battery in the cradle and run a full charge cycle before the first shift. The scan trigger and wireless radio together draw the highest inrush current when the cell is near minimum. A pre-charged pack prevents a false BMS trip that would otherwise cut the terminal mid-session on day one.

Cradle showing a charging error with a new pack installed

LXE cradles use contact resistance as part of the charge-initiation handshake. A new pack with oxidised or contaminated gold contacts will return a charging fault even though the battery itself is fine. Wipe the five contacts on the battery face with a dry lint-free cloth, reseat the terminal firmly in the cradle, and check that the cradle LED changes to amber within 10 seconds. If the error persists, check cradle contact spring tension — compressed springs on high-cycle docks are a common cause.

Scanner dropping wireless connection during rapid scan bursts

On the MX7, the 802.11 radio and the scan trigger fire simultaneously during fast barcode capture. That combined inrush can pull the cell voltage below the BMS undervoltage threshold for a few milliseconds, causing the radio stack to reset and drop the access point association. This happens most often when the battery is below 30% charge. The fix is to keep the pack above that level during shift — charge the terminal at break rather than running it flat. If dropouts occur on a fully charged new pack, check that the wireless polling interval in your RF network config is not set unusually aggressive.
