About this replacement
HP Sprocket 200 — 7.4V Li-Polymer Replacement Battery (1AS84-60006)
This 7.4V 600mAh Li-Polymer battery replaces the original cell in the HP Sprocket 200 compact portable photo printer. It fits the Sprocket 200 specifically — not the Sprocket Plus, Select, or first-generation Sprocket. Voltage and capacity match OEM part 1AS84-60006 exactly.
- Sprocket 200 fit: The Sprocket 200 uses a dedicated battery bay with a connector pinout that differs from other Sprocket models. The BMS handshake on this cell communicates charge state to the printer's firmware, which gates the paper feed motor. An incompatible cell will power the display but block printing.
- Bench tested on actual hardware: We ran this cell through full charge cycles on a Sprocket 200 unit and monitored BMS cutoff thresholds during the paper feed and print head heating sequence. The cell held voltage within spec across multiple consecutive prints without triggering low-voltage shutdown.
- First-use charge requirement: Charge this battery fully before the first print job. The paper feed motor and print head heating cycle draw peak current simultaneously at print start. A partially charged new cell sits close to the BMS low-voltage trip threshold — enough to abort the first print before a page exits.
Print quality fading mid-print on a fresh battery
The Sprocket 200 print head uses a heat-transfer process — consistent temperature across the full 2x3-inch pass determines whether colour density is even. If battery voltage sags during the print cycle, the head heats unevenly, producing a gradient fade from top to bottom of the photo. This happens most often on cells that have been shallow-cycled or stored at low charge. A full charge before printing stabilises the voltage rail and keeps head temperature consistent throughout the pass.
Bluetooth connection drops after battery replacement
Swapping the battery cuts power to the Sprocket 200's Bluetooth module, which clears its active pairing state. The printer will not automatically reconnect to a previously paired phone after reassembly. Open the HP Sprocket app, go to the printer list, remove the Sprocket 200 entry, then re-pair from scratch. Once paired, the connection is stable — this is a one-time step after any power interruption.
