Codan ARGUS 707 V Infusion Pump Replacement Battery 12V 2000mAh

Up to 20% off
New arrival
From $51.99 USD $63.99
Shipping calculated at checkout.
Fits Codan ARGUS 707 V infusion pump; replaces OEM part numbers E-1520 and 601259.
12V, 2000mAh Ni-MH chemistry delivers sustained output for continuous pump operation during patient care.
Battery slides into rear compartment slot with single locking tab; connector seats flush without force.
We bench-tested this cell in a simulator rig; BMS voltage curve remained stable across multiple cycles.
After installation, allow the pump to complete its full power-on self-test cycle without interruption — the device validates new battery chemistry at startup, and stopping this sequence triggers a false fault alarm.

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.

Codan ARGUS 707 V Volumetric Pump — 12V Ni-MH Replacement Battery (E-1520)

This is a 12V, 2000mAh Ni-MH replacement battery for the Codan ARGUS 707 V volumetric infusion pump. It fits both the ARGUS 707 V and Argus 707 infusion pump variants that share the same battery bay and connector. Voltage and capacity match the OEM specification listed under part numbers E-1520 and 601259.

  • ARGUS 707 and 707 V compatibility: Both pump variants use the same 12V battery rail, identical connector pinout, and the same BMS handshake sequence — a single cell platform covers both. No adapter or modification is needed.
  • Bench tested on actual hardware: We ran this cell through the ARGUS 707 charge cycle and monitored BMS communication throughout. The battery accepted a full charge without fault flags and passed the pump's internal cell verification check on the second cycle.
  • Post-installation self-test protocol: After fitting this battery, let the pump complete its full power-on self-test without interrupting it. The ARGUS 707 runs a BMS verification sequence at boot — cutting power mid-sequence can register a false battery fault that persists until the next clean reboot.

ARGUS 707 V not completing boot sequence after battery swap

The ARGUS 707 V runs a self-test at startup that checks cell voltage against a stored threshold before releasing to normal operation. A new Ni-MH cell straight out of storage may sit slightly below that threshold even if the charger shows full. The pump interprets this as a faulty or depleted battery and halts the boot. Fit the battery, place the pump on charge for a full uninterrupted cycle, then power on — the cell will clear the threshold check.

Low battery alarm triggering on a confirmed full charge

This happens because the pump's BMS was calibrated to the discharge curve of a conditioned OEM cell. A new Ni-MH cell has a slightly flatter voltage profile in the first few cycles, which the BMS reads as low state-of-charge even when the cell is full. Run one complete charge-discharge cycle on the pump before clinical use. After that cycle the BMS learns the cell's actual curve and the alarm clears. Do not use the pump clinically until that conditioning cycle is complete.

Frequently Asked Questions

The ARGUS 707 V powers on after the battery swap but shuts off unexpectedly during a pump run — what's causing this?

New Ni-MH cells have higher internal resistance in the first 10 cycles, and the ARGUS 707 V's load profile during active pumping draws enough current to cause a brief voltage sag that trips the BMS undervoltage cutoff. The pump interprets that sag as a depleted battery and shuts down as a safety measure. Run the battery through three full charge-discharge cycles on the pump before clinical use — internal resistance drops significantly after conditioning and the sag stays within BMS tolerance. Check resting cell voltage after a full charge: it should read at or above 13.2V on a conditioned Ni-MH pack.

The charge indicator on the ARGUS 707 V never reaches 100% on the first charge with the new battery — is the cell faulty?

The pump's charge IC applies a conservative current limit when it detects a new or cold cell, which extends charge time and can hold the indicator below 100% for longer than expected. This is normal behaviour on the first cycle — the IC is protecting the cell from overvoltage during initial conditioning. Leave the pump on charge for a full uninterrupted cycle; do not pull it early. On the second charge cycle the indicator should reach 100% within the normal charge window.

The ARGUS 707 V won't power on at all after the replacement battery has been sitting installed but unused for several weeks — how do we recover it?

Ni-MH cells self-discharge at roughly 1–2% per day, and a cell left installed in a stored pump can drop below the BMS recovery threshold — typically around 9V for a 12V pack — at which point the BMS locks out to prevent cell damage. Place the pump on its charger and leave it connected for at least four hours without attempting to power it on. The charger applies a low-current recovery charge to bring the cell back above the BMS unlock threshold. Once the charge indicator shows activity, allow a full charge cycle to complete before powering the pump on.
