Battery Care Tips
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
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 Control Enteral Feeding Pump / Pump 324 — 7.2V Ni-MH Replacement Battery (5-7905, 5-7920)
This is a 7.2V, 2000mAh Ni-MH replacement battery for the Kangaroo Control Enteral Feeding Pump and Pump 324. It powers the pump motor and control board during portable enteral feeding. Fits devices cross-referencing OEM part numbers 5-7905 and 5-7920.
- Control Enteral Feeding Pump and Pump 324 compatibility: Both models share the same 7.2V Ni-MH battery architecture, connector pinout, and BMS communication protocol. The same cell fits either platform without modification.
- Bench tested on actual hardware: We cycled this battery through charge and discharge on the Kangaroo pump platform. The BMS accepted the cell, completed its verification handshake, and held voltage within spec across the full discharge curve.
- Post-swap power-on sequence: After installing this battery, let the pump complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification cycle at startup — cutting power mid-sequence locks in a false battery fault that persists until the next clean reboot.
Low battery alarm triggering immediately after a confirmed full charge
The Kangaroo pump's BMS stores a learned capacity profile from the previous cell. When a new Ni-MH cell is installed, the BMS compares its resting voltage against the OEM threshold calibrated for an aged pack — a fresh cell at 7.2V nominal can read as "insufficient" until the learn cycle completes. This is not a fault with the replacement cell. Run one full charge-discharge cycle under normal pump operation, and the BMS recalibrates its low-battery threshold to match the new cell's actual voltage curve. After that single cycle, the alarm clears and does not return.
Pump fails to power on after the battery sat unused in storage
Ni-MH cells self-discharge during storage — a cell stored for several months can drop below the BMS recovery threshold, typically around 6.0V, which causes the pump to refuse to boot rather than attempt to run on an undervoltage pack. The BMS interprets this as a protection event, not a dead battery. Connect the pump to mains power first and allow the charger to pre-condition the cell for at least 30 minutes before attempting to power on independently. Once the cell voltage climbs above the BMS recovery threshold, the pump will boot and complete its self-test normally.

Frequently Asked Questions
The pump keeps shutting off mid-feed after I installed the new battery — is the cell defective?
This happens in the first several cycles of a new Ni-MH cell, not because the cell is defective. The Kangaroo pump's load profile draws sharp current pulses from the motor, and a new cell has higher internal resistance before its chemistry fully forms — the BMS sees a momentary voltage sag and trips the protection circuit. Run three to five full charge-discharge cycles under normal feed conditions and the internal resistance drops. Unexpected shutdowns stop once the cell has completed its break-in period.
The charge indicator never reaches 100% on the first charge — should I keep charging it?
The Kangaroo pump's charge IC applies a conservative current limit when it detects a new or cold cell, which means the first charge often terminates early before the indicator reaches 100%. This is intentional behaviour in the firmware, not a sign the cell is faulty. Allow the pump to complete that first charge undisturbed, then run a full discharge during normal use and charge again from zero. The indicator will read 100% correctly from the second cycle onward.
The self-test fails every time I reboot the pump since swapping the battery — what causes that?
The BMS has not yet completed its learn cycle on the new cell, so the self-test compares measured capacity against stored OEM parameters and flags a mismatch. This is a calibration state, not a hardware failure. Run one complete charge from flat to full without interrupting the pump, then allow the self-test to run through uninterrupted on the next boot. Once the BMS logs one full cycle, it updates its reference data and the self-test passes consistently. Do not interrupt the power-on sequence at any point during that first calibration boot.
