Huawei CV80 Photo Printer Compatible Battery 7.4V 500mAh

Huawei CV80 Photo Printer — 7.4V Li-Polymer Replacement Battery (P0925-HF)

This 7.4V, 500mAh lithium-polymer battery replaces the original P0925-HF cell in the Huawei CV80 portable photo printer. The CV80 is a Bluetooth-connected, pocket-sized photo printer that feeds and prints ZINK-style paper via a motor and print head driven entirely by this battery. When the original cell degrades, print quality and paper feed both suffer before the printer stops working altogether.

• CV80 compatibility: The CV80 uses a single lithium-polymer cell at 7.4V nominal to power both the paper feed motor and the thermal print head simultaneously. Any voltage deviation from that rail causes the BMS to cut output, stopping the print mid-cycle.
• Bench tested on actual hardware: We ran this cell through full charge cycles and triggered the feed motor and print head load simultaneously. The BMS held the voltage rail steady across both loads without tripping at the rated 500mAh capacity.
• First-charge print tip: Charge this battery to 100% before starting the first print job. The paper feed motor draws a surge current at startup that a partially charged new cell can trigger the BMS cutoff on — stopping the job before the first sheet finishes.

Print quality fading mid-sheet on a new battery

The CV80 thermal print head requires a stable voltage to heat evenly across each print line. If the battery cell has shallow-cycled or arrived partially discharged, the print head voltage sags under sustained load. That sag causes uneven heating, which shows up as faded bands or streaks across the photo. A full charge before printing stabilises the voltage and eliminates the sag.

Bluetooth pairing lost after battery replacement

Swapping the battery cuts power to the CV80's Bluetooth module, which clears the active pairing in memory. The printer does not reconnect automatically — it resets to an unpaired state. Open the Huawei printer app, delete the old device entry, then re-pair from scratch. The printer should appear in the app's device list within 30 seconds of powering on with the new battery at or above 7.4V.
