Bixolon SPP-R200/II Replacement Battery 7.4V 1100mAh

Bixolon SPP-R200/II Series — 7.4V Li-ion Replacement Battery (K409-00007A)

This 7.4V 1100mAh Li-ion battery replaces the original pack in the Bixolon SPP-R200, SPP-R200II, and SPP-R210 portable thermal printers. These compact receipt and label printers are used in retail, hospitality, and logistics — anywhere a corded printer isn't practical. Capacity matches OEM spec at 1100mAh (8.14Wh).

• SPP-R200 series compatibility: The SPP-R200, SPP-R200II, and SPP-R210 share the same battery bay geometry, 7.4V nominal rail, and BMS communication protocol — which is why one cell fits all three. The connector pinout and thermal cutoff thresholds are identical across the series.
• Bench tested on actual hardware: We cycled this battery through charge and discharge on an SPP-R200II unit. The BMS accepted the cell without fault codes, charge termination triggered correctly at full voltage, and the thermal print head drew stable current throughout the test print run.
• First-use print calibration: After installing, charge fully and print five test receipts before deploying to the field. The paper feed motor draws a specific current profile on startup — running a short calibration sequence confirms the BMS has set the correct current thresholds for the new cell.

Voltage sag under thermal head load in the SPP-R200 series

The SPP-R200's thermal print head pulls a sharp current spike each time it fires a heating element row. A degraded or deeply discharged battery can't sustain the voltage under that load, so the BMS trips to protect the cell. This shows up as mid-job shutdowns or incomplete print lines rather than a clean power-off. A fully charged, healthy cell holds the voltage rail steady through these spikes — if yours doesn't, the battery is the first thing to test before checking the head itself.

Bluetooth drops mid-job on the SPP-R200

The SPP-R200's Bluetooth radio and thermal head compete for current at the same moment — when a print job starts, both components draw simultaneously. At low battery charge, this combined load pulls the voltage below the radio's minimum operating threshold, causing the Bluetooth link to drop. The printer stays powered but the host device loses the connection and the job fails. Charge the battery above 7.2V before starting a multi-receipt print run to keep both subsystems stable.
