About this replacement
Creative PC-900 Pro / UP-7000 / UP-9000 — 11.1V Li-ion Replacement Battery (CR2302-0000005)
This 11.1V 5200mAh (57.72Wh) lithium-ion battery replaces the original power cell in the Creative PC-900 Pro portable ultrasound system and the UP-7000 and UP-9000 monitor series. It matches the OEM voltage rail and connector spec required by the device's onboard BMS. Use the Capacity value above — 5200mAh — as the authoritative figure for this listing.
- PC-900 Pro, UP-7000, UP-9000 shared platform: These models run the same 11.1V three-cell architecture with a common BMS handshake protocol. The connector pinout and cell configuration are identical across the platform, which is why one part number covers all listed fit models.
- Bench tested on actual hardware: We ran charge-discharge cycles on this cell and monitored BMS communication at startup. The protection circuit tripped correctly at low-voltage cutoff and resumed charging without faults after recovery.
- Power-on self-test protocol: After installation, allow the device to complete its full startup self-test without interruption. The BMS runs a verification sequence during boot. Interrupting it — even once — can trigger a persistent false battery fault that won't clear until the next complete reboot cycle.
Why the PC-900 Pro alarms low battery on a fully charged new cell
The PC-900 Pro's charge management IC compares the incoming cell's internal resistance and voltage profile against stored OEM chemistry parameters. A new cell that hasn't completed a full charge-discharge cycle doesn't yet match those parameters precisely. The device interprets the mismatch as a degraded or low battery condition and throws an alarm. Running one complete charge cycle — charge to full, discharge through normal use, charge again — lets the BMS calibrate against the actual cell chemistry and clears the alarm.
Device will not power on after the battery sat in storage
Lithium-ion cells self-discharge over time, and if a stored battery drops below approximately 9V (3V per cell), the BMS locks the output to prevent damage. The PC-900 Pro won't power on from this state — the device sees no voltage from the pack and treats it as absent. Connect the battery to a known-good charger and leave it for at least 30 minutes before attempting to power on. Most BMS circuits will accept a recovery charge once cell voltage climbs above the 9V threshold.
