About this replacement
LXE MX1 — 6V Ni-MH Replacement Battery (153521-0004)
This is a 6V 2000mAh Ni-MH replacement battery for the LXE MX1 handheld barcode scanner. It matches the OEM part number 153521-0004 and fits the MX1 used in retail, warehousing, and logistics environments. Voltage, capacity, and connector are matched to the original pack.
- MX1 platform fit: The MX1 uses a 6V Ni-MH chemistry with a specific BMS handshake through the cradle charging circuit. This replacement matches that voltage rail and connector pinout so the scanner recognises the pack and begins the charge cycle without errors.
- Bench tested on actual hardware: We cycled this pack through charge and discharge on the MX1 platform and confirmed the BMS accepted the cell without flagging a fault. Scan trigger response and wireless polling drew current as expected across the full discharge curve.
- Cradle charge before first shift: After installing this pack, place the MX1 in its charging cradle for a full cycle before pulling it into a pick-and-pack run. Scan trigger inrush current peaks when the cell is near minimum — a pre-charged pack prevents false BMS trips on the first shift.
Cradle showing a charging error on a new pack
The MX1 cradle reads pack contacts to verify chemistry and voltage before starting the charge cycle. If the contacts on the battery or cradle are dirty or oxidised, the dock sees high resistance and throws a charging error — even on a new pack. Wipe the gold contacts on both the battery and the cradle dock with a dry cloth, then reseat the pack firmly. If the error clears, the cell will begin charging normally within a few seconds.
Scanner losing wireless connection during rapid scan bursts
During a fast scan burst, the MX1 draws current simultaneously from the laser or imager and the wireless radio. When a Ni-MH cell is partially discharged, this combined inrush can cause a brief voltage sag that drops the radio below its minimum operating threshold. The connection drops, resets, and can cause missed transmissions back to the WMS. Keep the cell above 50% charge during high-frequency scanning shifts to stay clear of the sag threshold.
