About this replacement
Infinite Peripherals Linea Pro 4 — 3.7V Li-ion Replacement Battery (ICP663450M)
This 3.7V, 1200mAh Li-ion cell replaces the OEM ICP663450M battery in the Infinite Peripherals Linea Pro 4 mobile barcode scanner. The Linea Pro 4 attaches to an iPhone to deliver barcode scanning and wireless connectivity for retail and inventory workflows. Voltage and cell dimensions match the original pack exactly at 53.68 x 34.10 x 6.56mm.
- Linea Pro 4 platform fit: The Linea Pro 4 runs a single-cell 3.7V architecture with a BMS that monitors cell voltage, temperature, and current draw across both the barcode imager and the wireless radio simultaneously. Any replacement cell must match the OEM voltage rail and physical footprint — this pack does both.
- Bench tested on actual hardware: We cycled this pack through combined scan-trigger and wireless polling loads. The BMS responded correctly to inrush current on the scan burst without tripping into protective cutoff, and cell voltage held stable through discharge.
- First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before use on the floor. Scan-trigger inrush current is highest when the cell voltage is near minimum — a fully charged cell prevents false BMS trips during your first pick-and-pack shift.
Cradle showing a charging error on a new pack
A charging error on a freshly installed pack is almost always a contact resistance problem, not a faulty cell. The dock's charging contacts need a clean metal-to-metal connection to pass current and communicate battery state to the cradle firmware. Dust, oxidation, or a misaligned pack break that circuit and trigger the error flag. Wipe the gold contacts on both the pack and the cradle with a dry lint-free cloth, reseat the scanner firmly, and the charging indicator should clear within 30 seconds.
Scanner losing wireless connection during rapid scan bursts
Rapid scan bursts pull current from two sources at once — the imager firing and the wireless radio transmitting scan data. On a degraded or low cell, the combined inrush drops cell voltage below the radio module's minimum operating threshold, causing the wireless link to drop momentarily. The scanner may reconnect automatically, but the data from the burst is often lost. Charge the pack fully before a high-volume shift and check that cell voltage reads above 3.6V at rest before starting.
