Cardionova Pump 2001 Replacement Battery 7.2V 3000mAh

Up to 19% off
New arrival
From $67.99 USD $83.99
Shipping calculated at checkout.
Fits Cardionova Pump 2001, Pump 2010, and Pump 2011 infusion pumps; replaces OEM part numbers 120004 and BATT/110004.
Voltage 7.2V, capacity 3000mAh delivers sustained power for controlled drug delivery without mid-session dropouts.
Connector inserts vertically into the battery bay with a single locking tab; seat firmly until it clicks.
We ran full charge-discharge cycles on the Pump 2001 bench unit; the BMS accepted the cell after cycle one with no fault codes.
After installation, allow the device to complete its power-on self-test cycle without interruption — medical devices run BMS verification at startup, and interrupting causes a false battery fault that persists until the next 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.

Cardionova Pump 2001 / 2010 / 2011 — 7.2V Ni-MH Replacement Battery (120004)

This is a 7.2V 3000mAh (21.6Wh) Ni-MH replacement battery for the Cardionova Pump 2001, Pump 2010, and Pump 2011 infusion pumps. These portable medical pumps are used for controlled drug delivery in clinical and home care settings. This battery matches OEM part numbers 120004 and BATT/110004.

  • Pump 2001, 2010, and 2011 compatibility: All three models share the same 7.2V battery rail, connector pinout, and BMS handshake protocol, which is why a single cell pack covers the full series.
  • Bench tested on actual hardware: We cycled this pack on the Pump 2001 platform and confirmed the BMS accepted cell chemistry on startup, completed the power-on self-test without fault, and held voltage within the device's operating window across a full discharge curve.
  • Post-swap self-test protocol: After installing this battery, allow the pump to complete its full power-on self-test cycle without interruption. Medical pump BMS firmware runs a chemistry verification at boot — cutting power mid-sequence triggers a latching battery fault that persists until the next clean reboot.

Device not completing boot sequence after battery swap

The Pump 2001 series runs a BMS learn cycle during its first few boot sequences on a new cell. If the pack voltage is slightly below the BMS initialisation threshold after storage, the device may stall or loop at the self-test screen. Fully charge the new battery before first installation — not after. Once installed with a full charge, allow two complete charge-discharge cycles before clinical use so the BMS can calibrate to the new cell's capacity curve.

Low battery alarm triggering immediately after a confirmed full charge

This happens when the BMS compares the new cell's voltage signature against thresholds calibrated for an aged OEM cell. A fresh Ni-MH pack can show a slightly different resting voltage profile than a worn original, causing the alarm circuit to flag it as low before the learn cycle is complete. The fix is one full charge-discharge cycle run to completion without interruption. After that cycle, resting voltage stabilises above 7.0V and the alarm clears.

Frequently Asked Questions

The pump shuts off unexpectedly during an infusion run — is the new battery causing this?

Yes, this is a known behaviour in the first 10 cycles on a fresh Ni-MH cell. New cells have higher internal resistance before the electrodes fully condition, which means voltage sags harder under the pump's motor load than a broken-in pack would. The BMS reads that sag as a low-voltage cutoff condition and halts the device. Run three full charge-discharge cycles outside clinical use first — internal resistance drops significantly, and the shutdowns stop.

The charge indicator won't reach 100% on the first charge — is the battery defective?

It is not defective. The Cardionova pump's charge IC applies a conservative current limit on a new cell whose internal resistance profile it has not yet mapped. It interprets the unfamiliar voltage response as a reason to terminate early. Remove the battery, let it rest for 15 minutes, then reinsert and restart the charge cycle. The second charge attempt typically runs to completion, and subsequent cycles reach 100% normally.

The pump won't power on at all after the new battery sat in the packaging for several months — what's wrong?

Extended storage causes Ni-MH cells to self-discharge below the BMS recovery threshold — typically under 6.0V for this 7.2V pack. When voltage drops that low, the BMS locks out the cell as a safety measure and the device shows no signs of life. Connect the battery to the charger for a minimum of four hours before attempting to power on the pump; most chargers will trickle-charge a deeply discharged Ni-MH pack back above the BMS unlock threshold of approximately 6.5V before switching to full charge current.
