About this replacement
Datalogic LYNX — 3.7V Li-Polymer Replacement Battery (50-BTEC)
This 3.7V, 2000mAh Li-Polymer battery replaces the original pack in the Datalogic LYNX handheld barcode scanner. It fits models using OEM part numbers 50-BTEC, 50-BTSC, and 94ACC0065. The LYNX is a compact wireless scanner used in retail, warehousing, and inventory environments where constant scanning puts steady demand on the cell.
- LYNX platform compatibility: All three OEM part numbers share the same 3.7V cell format, connector pinout, and BMS handshake protocol on the LYNX. Swapping between these part numbers does not require firmware changes or reconfiguration on the host system.
- Bench tested on actual hardware: We cycled this pack through repeated scan-burst loads combined with active wireless polling. The BMS held cutoff thresholds correctly and the cell voltage recovered cleanly between draw events without false low-battery flags.
- First-shift preparation: After installing the new pack, seat the LYNX in its charging cradle and run a full charge cycle before putting the scanner into active pick-and-pack rotation. The scan trigger inrush current is highest when the cell is near minimum charge, and a fully charged cell prevents the BMS from tripping on the first heavy scan burst of the shift.
Cradle showing a charging error on a new LYNX battery pack
A charging error on a new pack almost always comes down to contact resistance at the dock, not a fault in the battery itself. Oxidation or debris on the cradle's charging pins prevents the dock from completing the handshake with the pack's BMS. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the scanner firmly until the cradle clicks. If the error clears, the pack is fine — the dock contacts were the issue.
Scanner losing wireless connection during rapid scan bursts
The LYNX draws from the same cell to power both the imager and the wireless radio simultaneously. During fast successive scans, the combined inrush from the scan trigger and the radio transmit pulse can cause a brief voltage sag that the wireless stack interprets as a drop event. This gets worse as the cell depletes toward the lower end of its charge curve. If dropouts cluster toward the end of a shift, the fix is to swap the battery before the cell falls below 3.5V rather than running it down to the BMS cutoff floor.
