About this replacement
Kangaroo ePump Enteral Feeding Pump — 4.8V Ni-MH Replacement Battery (F010484)
This is a 4.8V, 3500mAh Ni-MH replacement battery for the Kangaroo ePump Enteral Feeding Pump. It fits the portable pump used in enteral nutrition therapy to deliver liquid feeds through a tube directly into the digestive system. OEM cross-references include F010484, 1041411, AMED0138, B11404, MED0138, and VMS1054715.
- ePump compatibility: The ePump platform uses a 4.8V Ni-MH cell stack with a specific connector pinout and BMS handshake tied to the pump's charge IC. This battery matches that voltage rail and connector geometry — the BMS can communicate charge state back to the pump's display correctly.
- Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the ePump platform. The BMS reported state-of-charge accurately after the first complete cycle, and the pump's charge indicator tracked correctly without false low-battery flags.
- Post-installation self-test protocol: After fitting this battery, let the ePump complete its full power-on self-test without interruption. The pump's BMS runs a battery verification routine at startup — cutting power during this sequence writes a false fault state that will persist until a fresh, uninterrupted reboot.
Why the ePump triggers a low-battery alarm immediately after a confirmed full charge
The ePump's charge IC applies a chemistry-specific threshold when evaluating a new cell. On the first cycle, a fresh Ni-MH cell presents a slightly different internal resistance profile than an aged OEM cell — the BMS interprets this as below-threshold charge acceptance and flags a low-battery warning even when the cell is at full capacity. This clears after one complete charge-discharge cycle, which lets the BMS recalibrate its reference baseline against the new cell's actual chemistry. Run one full cycle before clinical deployment.
ePump not powering on after the battery sat unused in storage
Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. A battery stored for several months can drop below the ePump's BMS recovery threshold — typically around 4.0V for this pack — at which point the pump will not boot at all. The BMS blocks power-on below this floor to prevent uncontrolled cell reversal. Connect the pump to mains power and leave it on charge for a minimum of four hours before attempting to power on; this brings the cell voltage above the recovery threshold and allows the BMS to resume normal operation.
