Ahram Biosystems UF12-A Replacement Battery 11.1V 1700mAh

Ahram Biosystems UF12-A / Palm PCR G1-12 — 11.1V Li-ion Replacement Battery (UF12-A, P2010)

This is an 11.1V, 1700mAh lithium-ion battery that replaces the original cell in the Ahram Biosystems UF12-A and Palm PCR G1-12 portable medical devices. It matches the OEM voltage rail, connector footprint, and BMS communication profile. Capacity is 1700mAh (18.87Wh) — sourced from product data, not estimated.

• UF12-A and Palm PCR G1-12 compatibility: Both devices share the same 11.1V three-cell Li-ion architecture and draw from the same connector and BMS handshake specification. This battery carries OEM part references UF12-A and P2010, covering both platforms.
• Bench tested on actual hardware: We cycled this battery through charge and load on a clinical device bench. The BMS accepted the cell without fault flags, completed charge termination at 12.6V, and held voltage under load within the expected window for portable medical instrumentation.
• Post-swap self-test protocol: After installation, let the device run its full power-on self-test without interruption. Medical device BMS firmware runs a cell verification sequence at startup — cutting power during this window logs a battery fault that persists until the next complete reboot cycle.

Device not completing boot sequence after battery swap

The UF12-A and Palm PCR G1-12 run a BMS learn sequence during the first few boot cycles after a new cell is installed. If the device stalls mid-boot or loops back to the startup screen, the charge controller has not yet accepted the new cell's internal resistance profile. Run one full charge from flat to full, then allow the device to complete its boot sequence uninterrupted. Most devices clear this condition within two full charge-discharge cycles.

Self-test failure flagged immediately after confirmed full charge

A low-battery alarm or self-test failure on a freshly charged replacement is almost always a BMS threshold issue, not a faulty cell. The device's charge-assessment firmware compares internal resistance and resting voltage against OEM calibration values — a new cell that hasn't completed at least one full cycle reads outside this window. Charge the battery fully, run the device until the low-battery warning appears naturally, then charge again. After that conditioning cycle, the self-test threshold check passes on the next startup at or above 11.1V resting voltage.
