LXE 8650A376 Barcode Scanner Compatible Battery 3.7V 850mAh

LXE 8650 Bluetooth Ring Scanner Series — 3.7V Li-ion Replacement Battery (8650A376)

This 3.7V 850mAh Li-ion cell replaces part number 8650A376 in the LXE LX34L1-G and 8650/8670 Bluetooth Ring Scanners. These wearable scanners are used in warehouse pick-and-pack and retail inventory operations where the battery sits close to the wrist and powers both the scan engine and Bluetooth radio simultaneously. Capacity figures come from the product data — 3.15Wh total energy at 3.7V nominal.

• LX34L1-G and 8650/8670 compatibility: All three models share the same 3.7V cell footprint, connector pinout, and BMS handshake protocol. The ring form factor keeps the battery cavity compact — at 40.20 × 35.30 × 6.10mm, dimensional tolerance matters more here than in pistol-grip scanners.
• Bench tested on actual hardware: We cycled this pack through scan-trigger and Bluetooth radio load simultaneously. The BMS held its cutoff thresholds without nuisance tripping under combined inrush draw, and cell voltage recovery after burst scanning came back within spec each cycle.
• First-shift preparation for ring scanners: After installing, seat the scanner in its cradle and run a full charge cycle before the shift starts. The scan trigger inrush current peaks when the cell is near its minimum — a fully charged cell prevents false BMS trips the first time an operator pulls the trigger at the start of a busy shift.

Cradle showing charging error on a new pack

The LXE cradle reads battery state through the dock contacts before it opens the charge circuit. If those contacts have oxidation or debris from warehouse handling, the cradle throws a charging error even on a healthy new pack. Remove the scanner, wipe the gold contacts on both the pack and the cradle with a dry cloth, then reseat firmly. If the error clears within 30 seconds, contact resistance was the cause — not the battery or the dock firmware.

Scanner losing Bluetooth connection during rapid scan bursts

The 8650/8670 runs its Bluetooth radio and scan engine off the same 3.7V cell with no secondary rail. During rapid consecutive scans, combined inrush from the imager and the radio transmitter causes a momentary voltage sag. If the cell is already degraded or partially discharged, that sag drops below the radio module's minimum operating voltage and the connection drops. Start the shift on a full charge and check that cell voltage at rest reads above 3.9V — if it reads below 3.7V at rest, the pack is not holding charge between shifts and needs replacement.
