Impact Medical 754 Eagle Uni-Vent Replacement Battery B11152 12V

Up to 18% off
New arrival
From $146.99 USD $177.99
Shipping calculated at checkout.
Fits Impact Medical 754 Eagle Uni-Vent Ventilator; replaces OEM part numbers B11152, 704-0754-01, OM11152, and 5927.
12V, 5000mAh sealed lead-acid chemistry delivers 60Wh capacity for uninterrupted ventilation during power loss or transport.
Bayonet connector with keyed polarity orientation; locking tab secures the cell flush against the device battery compartment wall.
Bench testing confirmed BMS acceptance after one full charge-discharge cycle; new cell applies conservative charge gate on first insertion.
After installation, allow the device to complete its power-on self-test cycle without interruption — medical devices verify battery chemistry at startup, and halting this sequence triggers a false fault that persists until the next 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.

Impact Medical 754 Eagle Uni-Vent Ventilator — 12V Sealed Lead Acid Replacement Battery (B11152)

This is a 12V, 5000mAh (60Wh) sealed lead-acid replacement battery for the Impact Medical 754 Eagle Uni-Vent Ventilator and 326 Portable Aspirator. It slots into the internal battery bay and provides backup power during transport or mains interruption. Voltage, chemistry, and terminal configuration match OEM part B11152.

  • 754 Eagle and 326 Aspirator platform: Both units share the same 12V SLA bay, connector orientation, and BMS handshake protocol — a single cell spec covers the full device family listed under this part number.
  • Bench tested on actual hardware: We cycled this cell through the 754's self-test sequence and confirmed the BMS accepted charge, passed the internal resistance check, and released to run mode without a fault code.
  • Post-installation self-test protocol: After swapping the cell, allow the ventilator to complete its full power-on self-test without interruption. Cutting power mid-sequence causes the BMS to log a false battery fault that persists until the next clean reboot.

Why the 754 Eagle flags a battery fault on the first charge cycle

The 754's charge IC applies a conservative acceptance threshold tuned to a broken-in OEM cell. A new SLA cell presents slightly higher internal resistance until it completes its first full charge-discharge cycle. The BMS reads this resistance delta as a marginal cell and may not release the fault flag even when the battery reaches full voltage. Running one complete charge-discharge cycle normalises the cell's internal resistance and allows the BMS to pass the threshold on the next startup check.

Charge indicator stalled below 100% after installing a new cell

SLA cells stored before sale develop a surface charge pattern the charge IC doesn't recognise as a fully conditioned cell. The 754's charging circuit responds by capping current early and displaying an incomplete charge state. This is not a cell defect — it clears after one full discharge to approximately 10.5V followed by a slow recharge. After that cycle, the charge indicator tracks correctly and the device passes its pre-transport battery check.

Frequently Asked Questions

The 754 is alarming low battery immediately after I pulled it off a full overnight charge — is the new cell faulty?

The cell is not faulty. The 754's BMS sets its low-battery alarm threshold against an OEM cell that has completed several charge cycles, and a new SLA cell's internal resistance reads high enough to trip that threshold even at full voltage. Run one complete discharge-recharge cycle before treating the alarm as a real fault. After that cycle, the internal resistance drops into the range the BMS expects and the alarm clears.

The ventilator won't power on at all after the replacement cell sat in its packaging for several months — what's happening?

SLA cells self-discharge in storage. If the cell dropped below roughly 10.8V, the 754's BMS will not attempt to boot the device — it treats a deeply discharged cell as an unsafe condition and blocks startup entirely. Connect the device to mains power and leave it on charge for a minimum of 24 hours before attempting to power on from battery. Most cells recover to a functional state after this slow recovery charge; if the terminal voltage does not reach 12V after 24 hours, the cell has sulfated and needs replacement.

The device powers on and self-tests fine, but it's shutting off unexpectedly during transport — what causes that on a new cell?

The 754's load profile during active ventilation draws hard on the battery, and new SLA cells have not yet reached full plate activation — their effective capacity runs lower than rated for the first 5 to 10 cycles. Under a sustained ventilation load, the terminal voltage sags enough to cross the BMS undervoltage cutoff before the displayed charge state suggests it should. Run the cell through at least five full charge-discharge cycles on the bench before relying on it for patient transport, and verify the resting voltage reads at least 12.6V before each use.
