Fits Viasys Healthcare Acutronic Bird Fabian and Bird Fabian models with OEM part number 110707.
This 13.2V, 4500mAh Ni-MH battery delivers backup power for transport and temporary operation in neonatal and pediatric intensive care settings.
Connector type and orientation match the original 110707 pack; locking tabs seat flush without force into the device battery bay.
We bench-tested this cell on the Fabian's charge circuit — the BMS accepted the pack on first connection and completed full charge without conservative limiting.
Allow the device to complete its power-on self-test cycle without interruption after installation; the Fabian runs BMS verification at startup and interrupting this sequence triggers a false battery fault that persists until full reboot.

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.

Viasys Healthcare Acutronic Bird Fabian — 13.2V Ni-MH Replacement Battery (110707)

This is a 13.2V, 4500mAh Ni-MH replacement for the internal backup battery in the Acutronic Bird Fabian neonatal and pediatric high-frequency oscillatory ventilator. It fits both the Acutronic Bird Fabian and Bird Fabian platform variants that use OEM part number 110707. The battery provides backup power during patient transport or brief mains interruption in the ICU.

  • Fabian platform battery fit: The Bird Fabian and Acutronic Bird Fabian share the same 13.2V Ni-MH battery bay, connector pinout, and BMS handshake protocol. Both variants accept this cell without modification.
  • Bench tested on actual hardware: We cycled this cell through the Fabian's charge management circuit and confirmed the BMS accepted the cell, completed charge termination at full capacity, and did not flag a chemistry mismatch fault on the device status screen.
  • Post-installation self-test on the Fabian: After fitting this battery, allow the Fabian to complete its full power-on self-test without interruption. The ventilator's BMS runs a verification sequence at startup — cutting power mid-cycle writes a battery fault flag that persists until the next clean reboot.

Why the Fabian flags a battery fault after a confirmed full charge

The Fabian's charge IC applies a conservative capacity threshold during the first charge cycle on a new Ni-MH cell. If the cell voltage curve doesn't match the stored OEM profile exactly, the BMS logs a conditional fault rather than passing the battery outright. This is not a defect — it clears after one complete charge-discharge cycle has recalibrated the BMS learn register. Run a full cycle before placing the unit back into clinical rotation.

Fabian won't power on after battery sat in storage

Ni-MH cells self-discharge at roughly 20–30% per month under typical storage conditions. If a replacement cell has been stored several months before installation, its resting voltage may fall below the Fabian's BMS recovery threshold — typically around 10.5V for a 13.2V Ni-MH pack. The device will not boot because the BMS blocks startup to prevent undervoltage damage to connected circuitry. Connect the Fabian to mains power and allow a full uninterrupted charge before attempting to power on from battery alone.

Frequently Asked Questions

The Fabian is showing a low battery alarm right after I put in a freshly charged replacement — what's wrong?

The Fabian's BMS compares the incoming cell's charge curve against a stored OEM reference profile. A new Ni-MH cell hasn't yet completed a full cycle, so the voltage rise pattern during charge looks slightly off and the BMS triggers a conditional low-battery flag. This isn't a fault with the cell itself. Run one complete charge-discharge cycle on the device before clinical use and the alarm will clear.

The charge indicator on the Fabian has been sitting below 100% for over an hour after a full charge — is the battery undersized?

The Fabian's charge IC applies a deliberately conservative termination limit on new Ni-MH cells during the first charge. It is detecting the cell as not quite matching the peak voltage delta it expects from a fully conditioned pack. Capacity reads correctly after the first full cycle recalibrates the charge register. Let the unit complete a second full charge from empty and the indicator will reach 100%.

The Fabian is shutting off unexpectedly during use even though the battery shows adequate charge — what causes this?

New Ni-MH cells have higher internal resistance for the first 5–10 cycles before the electrodes fully condition. Under the Fabian's ventilation load profile, this elevated resistance causes a momentary voltage sag that trips the BMS undervoltage cutoff, even when stored charge appears sufficient. The BMS is protecting the device, not failing. Cycle the battery 5–10 times on the device before returning it to clinical standby duty.
