About this replacement
HP OfficeJet 200 / 250 Series Mobile Printer — 11.1V Li-ion Replacement Battery (CZ993-60017)
This 11.1V, 1050mAh Li-ion battery replaces the OEM CZ993-60017 cell in HP's mobile printer lineup. It fits the OfficeJet 200, 250, 252, and 252C Mobile Printers — any model that shares this battery bay and voltage rail. Pull the old cell, seat this one, and the printer returns to cordless operation.
- OfficeJet 200 / 250 / 252 series fit: These models share the same 11.1V three-cell Li-ion architecture, identical connector pinout, and the same BMS handshake protocol — so one battery services the full range without modification.
- Bench tested on actual hardware: We cycled this cell through the printer's startup sequence — motor drive, printhead heating element, and wireless radio all active simultaneously. The BMS held without tripping the overcurrent threshold during the peak draw at job start.
- First print cycle preparation: Charge this battery to full before running the first print job. The heating element and feed motor pull peak current at startup — a partially charged cell can trip the BMS before the first page clears the tray.
WiFi dropping mid-job on the OfficeJet 250
The OfficeJet 250 runs its wireless radio, feed motor, and printhead heater off the same battery simultaneously. Under that combined draw, a degraded or low cell can't hold voltage above the radio's minimum threshold. When voltage sags, the wireless module resets to protect itself — mid-job. The fix is simple: keep the battery above 40% charge before starting multi-page wireless jobs, and let the cell rest at full charge for 30 minutes after a deep drain before printing again.
Print quality drops before the battery indicator shows low
The printhead heating element is voltage-sensitive — it needs a stable supply to reach and hold the correct firing temperature. As the cell discharges past roughly 20%, voltage sag causes the heater to undershoot, producing faded lines, streaks, or inconsistent ink placement. The battery gauge lags behind actual cell voltage under load, so the indicator can still show one bar while print quality has already degraded. Finish long print jobs before the cell drops below 20%, or recharge to at least 11.5V resting voltage before resuming.
