About this replacement
Newland NLS-BS80 — 3.7V Li-Polymer Replacement Battery (1100020105)
This 3.7V 950mAh lithium-polymer cell replaces the original battery in the Newland NLS-BS80 handheld barcode scanner. It matches OEM part numbers 1100020105 and BTY81. The NLS-BS80 is a compact handheld scanner used in retail, warehouse, and logistics environments for rapid barcode reading and inventory tracking.
- NLS-BS80 platform fit: The BS80 uses a dedicated Li-Polymer cell sized to the scanner's slim housing — 43.00 x 25.40 x 10.00mm. The BMS on this unit monitors cell voltage and cuts power to the scan trigger below a set floor, so cell capacity and discharge curve must match OEM spec closely.
- Bench tested on actual hardware: We cycled this pack through repeated scan trigger bursts combined with wireless polling loads. The BMS handled combined inrush without nuisance trips, and voltage held stable across the mid-charge range where most scan shifts operate.
- First-shift preparation: After installing the new pack, seat the scanner in its cradle and run a full charge cycle before starting pick-and-pack. Scan trigger inrush is highest near minimum cell voltage — a fully charged cell prevents false BMS trips during the opening minutes of the first shift.
Cradle showing a charging error on a freshly installed pack
The BS80 cradle reads pack contacts to confirm a valid cell before starting the charge cycle. If contact pads on the battery or dock have oxidation or debris, the cradle throws a fault rather than charging. This is not a defective cell — it is a contact resistance issue. Wipe the gold pads on the battery and the cradle contact pins with a dry cloth, reseat the scanner firmly, and the charging indicator should clear within 15 seconds.
Scanner drops wireless connection mid-scan burst
During a rapid scan burst, the BS80 draws current for both the imager and its wireless radio simultaneously. When the cell is partly depleted, that combined inrush pulls voltage briefly below the radio module's operating threshold — and the wireless link drops. This is not a pairing fault. Recharge the pack before the shift reaches the lower half of the charge state, and the radio will maintain its connection through sustained burst scanning.
