LXE MX6 Barcode Scanner Replacement Battery 7.4V 3400mAh

LXE MX6 — 7.4V Li-ion Replacement Battery (200-00591-01)

This is a 7.4V, 3400mAh lithium-ion battery for the LXE MX6 mobile data terminal. It fits the MX6 handheld used in warehouse and inventory operations. Voltage and capacity match the OEM specification exactly.

• MX6 platform fit: The MX6 uses a 7.4V two-cell Li-ion pack with a BMS that validates cell voltage and NTC temperature data before the device will boot. This replacement carries the same connector pinout and BMS handshake logic the MX6 expects, so the terminal recognises the pack on first insertion.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on the MX6 platform. The BMS held stable across scan-trigger inrush events and sustained wireless radio load. No false low-voltage cutoffs were recorded during testing.
• First-shift prep on the MX6: After installing this battery, seat the MX6 in its cradle and run a full charge cycle before putting the unit into pick-and-pack rotation. Scan-trigger inrush current spikes highest when the cell is near minimum charge — a pre-charged pack prevents the BMS from tripping on the first shift draw.

Cradle showing a charging error on a new pack

The MX6 cradle reads contact resistance at the charge pins before it opens the charge circuit. If dock contacts or battery terminals have oxidation or debris, resistance reads high and the cradle flags a fault instead of charging. Wipe the gold contacts on both the battery and the cradle dock with a dry lint-free cloth, then reseat the unit firmly. If the error clears, run the unit through a full cycle before returning it to the floor.

Scanner losing wireless connection during rapid scan bursts

During rapid scanning, the MX6 draws simultaneously from the scan trigger and the wireless radio — two inrush events stacking within milliseconds. A degraded or partially charged battery sags below the radio module's minimum operating voltage under this combined load, dropping the wireless link mid-session. This is not a radio fault — it is a voltage-sag event. Charge the replacement pack to full before the shift and confirm resting voltage is at or above 7.4V before deployment.
