Fujitsu Stylistic 500 Replacement Battery 7.4V 2200mAh

Fujitsu Stylistic 500 — 7.4V Li-ion Replacement Battery (FMWBP4)

This is a 7.4V, 2200mAh Li-ion battery for the Fujitsu Stylistic 500 handheld computing terminal. It fits the Stylistic 500 barcode scanner used in retail and logistics environments. OEM part numbers covered include FMWBP4, FMWBP4(2), NP-500, NP-500H, NP-510, NP-520, NP-530, and CA54200-0090.

• Stylistic 500 platform fit: These OEM part numbers all share the same 7.4V cell configuration, physical connector, and BMS handshake. The Stylistic 500's onboard charging circuit recognises the pack through a specific resistance signature — this replacement meets that spec so the device does not flag a foreign battery warning.
• Bench tested on actual hardware: We ran this pack on a Stylistic 500 unit and cycled through rapid scan bursts while monitoring the BMS cutoff threshold. The protection circuit held stable across repeated inrush events from the scan trigger and wireless radio polling simultaneously.
• First-shift preparation: After installing, seat the scanner in its cradle for a full charge cycle before use in pick-and-pack. Scan trigger inrush current is highest when the cell is near minimum voltage — a fully pre-charged cell prevents false BMS trips during the first shift.

Cradle showing a charging error on a new pack

Charging docks on the Stylistic 500 read pack state through pogo-pin contacts on the base of the battery. Oxidation or debris on those contacts raises resistance enough for the cradle to report a fault rather than begin a charge cycle. Wipe the contacts on both the pack and the cradle dock with a dry cloth, then reseat the pack firmly. The cradle should clear the error and begin charging within 30 seconds of a clean, seated connection.

Scanner losing wireless connection during a rapid scan burst

The Stylistic 500 draws from the same cell for both the wireless radio and the scan trigger. During a rapid burst — multiple scans per second — the combined inrush can cause a momentary voltage sag below the BMS protection floor, which drops the radio link before the BMS fully trips. This is more likely when the cell is below 50% charge. If dropouts happen mid-shift, charge the pack before it falls below the halfway mark and confirm the cell voltage reads above 7.0V under load.
