About this replacement
HP Deskjet 460 Series — 11.1V Li-ion Replacement Battery (C8222A)
This 11.1V, 2300mAh Li-ion battery replaces the original C8222A cell used in the HP Deskjet 460 series portable printers and the BT500 Bluetooth USB 2.0 Wireless Adapter. It fits the Deskjet 460, 460c, and 460cb, among other models in the lineup. Same voltage, same connector, same BMS handshake as the factory pack.
- Deskjet 460 series compatibility: These models share the same 11.1V three-cell architecture, connector pinout, and BMS communication protocol. The printer's controller checks cell status at power-on — a pack that doesn't respond correctly triggers a fault before any print job starts.
- Bench tested on actual hardware: We cycled this pack through full charge and multiple print jobs on a Deskjet 460cb. The BMS held charge across the discharge curve without tripping the overcurrent cutoff, and the printer accepted the pack without a battery error flag.
- First-use charge on portable printer batteries: Charge this pack to 100% before your first print run. The motor drive and heating element pull peak current simultaneously at startup — a partially charged cell sitting at 10.2V or below can trip the BMS on that first cycle and leave the printer unresponsive.
Why the Deskjet 460 stops mid-job on a seemingly charged battery
The 460's heating element and paper feed motor both draw current at the same moment during a print cycle. Under combined load, a degraded or partially charged cell can sag below the BMS undervoltage threshold — around 9.0V at the pack level — even if the status indicator shows bars remaining. The BMS then cuts output to protect the cells, and the printer halts mid-job. A fresh, fully charged pack at 12.6V at rest has enough headroom to handle this combined draw without sagging into cutoff.
Print job starts but output fades or streaks before the battery reads low
The thermal printhead on the 460 series is voltage-sensitive — output quality drops when pack voltage dips under sustained load, even before the low-battery indicator triggers. This typically happens when the cell capacity has faded through repeated shallow cycles, so the pack reads "charged" but can't hold voltage under load. The printer's gauge reads state of charge, not load capacity, so it won't warn you until the voltage collapse is severe. If print quality degrades before the indicator hits low, replace the pack and avoid letting it discharge below 20% under normal use.
