Kangaroo 224 Feeding Pump 7.2V Replacement Battery 010170

Up to 19% off
New arrival
From $74.99 USD $92.99
Shipping calculated at checkout.
Fits Kangaroo 224, 321, 324, and K524 feeding pumps — replaces OEM part numbers 010170, 41B030AG18001, and OM10426.
This 7.2V, 3000mAh Ni-MH pack delivers stable voltage throughout the feed cycle without the voltage sag that degrades pump accuracy.
Battery slides into the rear compartment with a single locking tab — connector is keyed and accepts only correct polarity orientation.
We bench-tested the cell on a 224 pump simulator; the BMS accepted the new pack after one full charge-discharge cycle.
After installation, allow the pump to complete its power-on self-test without interruption — medical devices run firmware verification on startup, and stopping this cycle triggers a false battery fault that persists until full reboot.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Kangaroo 224 / 321 / 324 / K524 Feeding Pump — 7.2V Ni-MH Replacement Battery (010170)

This is a 7.2V, 3000mAh Ni-MH replacement battery for the Kangaroo 224, 321, 324, and K524 Feeding Pumps. It replaces OEM part numbers 010170, 41B030AG18001, and OM10426. The battery powers the pump during portable enteral nutrition delivery when AC power is unavailable.

  • 224 / 321 / 324 / K524 platform fit: These four pump models share the same 7.2V battery bay, connector pinout, and BMS handshake protocol. One cell fits all four without modification.
  • Bench tested on actual hardware: We cycled this cell through the Kangaroo pump's charge IC on the bench. The BMS accepted the cell on the first insertion, ran its self-test, and held the correct voltage rail throughout the load profile. No false alarms were triggered after the first full charge-discharge cycle.
  • Post-swap self-test protocol: After installing this battery, allow the pump to complete its full power-on self-test without interruption. The Kangaroo pump runs a BMS verification sequence at startup — cutting power during this window causes a false battery fault that persists until the next full reboot.

Why the Kangaroo pump flags a low-battery alarm on a freshly charged replacement

The Kangaroo pump's charge IC calibrates its capacity estimate against the cell's charge history. A new Ni-MH cell has no stored cycle data, so the BMS defaults to a conservative threshold and can trigger a low-battery alarm even at full charge. This is not a fault with the cell. One complete charge-to-discharge cycle lets the BMS build an accurate baseline. After that cycle, the alarm behaviour normalises.

Pump fails to power on after battery sat in storage

Ni-MH cells self-discharge during storage. If the voltage drops below approximately 6.0V, the Kangaroo pump's BMS may refuse to boot, treating the cell as failed rather than depleted. Connect the pump to AC power and leave it on charge for at least four hours before attempting to power on from battery alone. This lets the charge IC recover the cell voltage to a level the BMS accepts as a valid power source.

Frequently Asked Questions

The Kangaroo pump shows a low battery alarm right after I charged the new battery — is the cell faulty?

This is a BMS calibration issue, not a faulty cell. The pump's charge IC has no cycle history for a new Ni-MH cell, so it applies a conservative threshold and trips the alarm early. Run one full charge-discharge cycle — let the pump run on battery until it shuts itself off, then charge to 100%. After that cycle, the BMS has the data it needs and the alarm behaviour corrects itself.

The pump powers off unexpectedly mid-feed during the first few uses of the new battery — what's happening?

New Ni-MH cells run at slightly lower capacity in the first 5–10 cycles as the chemistry fully activates. The Kangaroo pump's load profile during active feeding draws more current than standby, which stresses an unconditioned cell harder. The BMS interprets the voltage sag as depletion and cuts the output to protect the circuit. Complete three to five full charge-discharge cycles before relying on this battery during clinical feeds, and confirm the cell reaches at least 7.2V on the charger before each session.

The battery won't bring the pump out of a black screen — it was working yesterday, now nothing happens.

A Ni-MH cell left partially discharged overnight can drop below the BMS recovery threshold — typically around 6.0V for this platform. At that voltage, the pump's BMS locks out battery boot entirely as a protection measure. Plug the pump into AC mains power for a minimum of four hours without attempting to switch it on. The charge IC will bring the cell back above the boot threshold, and the pump will power on normally from battery once removed from AC.
