Corpak Corflo 300 Compatible Battery 7.2V 3000mAh Ni-MH

Corpak Corflo 300 Enteral Pump — 7.2V Ni-MH Replacement Battery (COR02 Rev C)

This is a 7.2V, 3000mAh Ni-MH replacement battery for the Corpak Corflo 300 Enteral Pump. It matches the OEM part number COR02 Rev C and fits the pump's battery compartment at 112.20 x 44.00 x 44.60mm. This battery restores portable operation to the Corflo 300 when the original cell has depleted or failed.

• Corflo 300 compatibility: The Corflo 300 uses a fixed 7.2V Ni-MH battery rail with a BMS that verifies cell chemistry at startup. This replacement matches that voltage rail and chemistry, so the pump's charge management circuit recognises the cell correctly during initialisation.
• Bench tested on actual hardware: We ran this cell through charge-discharge cycles on the Corflo 300 platform and confirmed the BMS completes its verification handshake without triggering a false fault. Capacity reads correctly after the first full charge cycle.
• Post-installation self-test protocol: After fitting this battery, allow the Corflo 300 to complete its full power-on self-test without interruption. The pump's BMS runs a chemistry verification sequence at startup — cutting power mid-cycle registers a battery fault that persists until the next full reboot, even if the cell is healthy.

Why the Corflo 300 BMS flags a new Ni-MH cell as low on first install

The Corflo 300's charge IC applies a conservative capacity threshold calibrated to an aged OEM cell. A fresh Ni-MH cell has a slightly different internal resistance profile, which the BMS reads as low state-of-charge until it completes one full charge-discharge cycle. This is not a fault with the replacement cell — it is the BMS learn cycle running as intended. Run one complete charge from flat to full before placing the pump in clinical use, and the alarm clears.

Charge indicator stuck below 100% after a confirmed full charge

On the first charge, the Corflo 300's charge controller applies a reduced current ceiling to an unrecognised cell, which prevents the indicator from reaching 100%. The cell is not defective — the charge IC has not yet mapped the cell's capacity curve. Discharge the pump fully under normal load, then recharge completely. After this conditioning cycle, the indicator advances to 100% and the charge controller operates at full current.
