Kangaroo ePump F010484 Replacement Battery 4.8V 3800mAh

Kangaroo ePump Enteral Feeding Pump — 4.8V Ni-MH Replacement Battery (F010484)

This is a 4.8V, 3800mAh Ni-MH replacement battery for the Kangaroo ePump Enteral Feeding Pump. It replaces OEM part numbers F010484, 382400, 1041411, and B11404. The ePump delivers nutritional formula through a feeding tube, and this battery powers both the pump motor and its onboard control systems.

• ePump platform compatibility: The ePump feeding pump line shares a consistent 4.8V Ni-MH battery architecture across its variants. The connector pinout, BMS communication protocol, and voltage rail requirements are identical across these models — one cell pack covers all of them.
• Bench tested on actual hardware: We ran this battery through the ePump's power-on sequence and confirmed the BMS handshake completed without fault flags. The pump motor engaged at normal torque and the control board accepted the cell state-of-charge reading without triggering a battery warning.
• Post-swap self-test protocol: After installing this battery, let the ePump complete its full power-on self-test without interrupting the sequence. The device runs a BMS verification cycle at startup — cutting power during this window writes a battery fault to the log that persists until the next clean reboot. Let it finish before advancing to any clinical use screen.

Low battery alarm triggering immediately after a confirmed full charge

The ePump's charge IC applies a conservative acceptance threshold calibrated to the OEM cell's internal resistance profile. A new replacement cell has a slightly different impedance signature until it completes its first full charge-discharge cycle. The BMS reads this mismatch as an incomplete charge state and raises the alarm pre-emptively. Run one full charge-discharge cycle before clinical deployment — after that cycle, the BMS recalibrates to the new cell and the alarm clears.

ePump will not power on after the battery sat unused in storage

Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. A cell stored for several months can drop below the ePump's minimum BMS recovery threshold — typically around 4.0V for a 4.8V pack — and the device will not boot. Connect the pump to mains power first and allow a trickle charge to restore the cell voltage above the recovery floor before attempting to power on from battery alone. Once the charge indicator shows any movement, the BMS has re-initialised and the boot sequence will complete normally.
