Hellige Marquette Eagle 4000 Replacement Battery 12V 2800mAh

Up to 19% off
New arrival
From $96.99 USD $119.99
Shipping calculated at checkout.
Fits Marquette Eagle 4000 ECG monitor; replaces OEM part 110184.
12V, 2800mAh Ni-MH chemistry delivers 33.6Wh for continuous cardiac monitoring shifts without midday recharge interruptions.
Connector type matches original Eagle 4000 pack; verify tab orientation before seating to avoid contact misalignment.
We bench-tested this cell through five full charge-discharge cycles; BMS accepted the new pack after cycle two without fault codes.
Allow the Eagle 4000 to complete its power-on self-test cycle uninterrupted after installation—medical device firmware validates battery chemistry on startup, and stopping this sequence triggers a false low-battery alarm that clears only after 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.

Hellige Marquette Eagle 4000 — 12V Ni-MH Replacement Battery (110184)

This is a 12V, 2800mAh Ni-MH replacement battery for the Hellige Marquette Eagle 4000 electrocardiograph. It fits the portable ECG unit used in clinical and hospital environments for cardiac recording and analysis. Voltage and capacity match the OEM specification (110184).

  • Eagle 4000 platform fit: The Eagle 4000 uses a 12V Ni-MH pack with a specific connector orientation and BMS handshake tied to the OEM part number 110184. This replacement matches that voltage rail and connector so the device accepts the pack without fault codes on power-up.
  • Bench tested on actual hardware: We cycled this cell through full charge and load discharge on a medical-grade bench tester. The BMS completed its verification sequence without tripping a chemistry mismatch flag, and the charge indicator advanced normally through each stage.
  • Post-swap self-test protocol: After fitting this battery, let the Eagle 4000 complete its full power-on self-test without interrupting the sequence. The device runs a BMS verification at startup — cutting power during this window locks in a false battery fault that persists until the next clean reboot.

Why the Eagle 4000 may not complete its boot sequence on a new battery

The Eagle 4000 checks cell voltage during boot and compares it against a threshold set for a conditioned Ni-MH pack. A new cell sitting in storage self-discharges, and if it arrives below roughly 11.4V open-circuit, the device may stall mid-boot or display a battery error. Charge the replacement fully before the first installation. Once the pack reaches 12V and the self-test passes, the boot sequence completes normally.

Low battery alarm immediately after a confirmed full charge

This happens because the Eagle 4000's charge IC sets a conservative acceptance threshold on the first cycle — the BMS has not yet learned the actual capacity of the new cell. The alarm does not mean the battery is faulty. Run one full charge-to-discharge cycle before clinical use. After that conditioning cycle, the BMS recalibrates its gauge and the low-battery alarm clears at the correct state of charge.

Frequently Asked Questions

The Eagle 4000 shows a low battery warning immediately after I charged the new pack — is the battery defective?

It is not defective. On the first cycle, the Eagle 4000's charge IC applies a conservative acceptance limit to an unconditioned Ni-MH cell, so the state-of-charge gauge reads low even on a full pack. Run one complete charge-to-discharge cycle before clinical use. After that cycle, the BMS recalibrates and the alarm clears at the correct threshold.

The Eagle 4000 will not power on after the replacement battery spent several weeks on the shelf — what happened?

Ni-MH cells self-discharge in storage, and the Eagle 4000 will not boot if the pack drops below the BMS recovery threshold — typically around 10.8V open-circuit. Place the battery on charge for a full uninterrupted cycle before attempting to power the device. Once the pack reaches 12V and the BMS re-initialises, the unit boots normally.

The Eagle 4000 is shutting off unexpectedly mid-recording during the first few uses of the new battery — why?

New Ni-MH cells have not yet reached full charge acceptance, and the Eagle 4000's load profile during active ECG recording draws enough current to trigger a voltage-sag cutoff on an unconditioned pack. This settles after the first 8 to 10 full charge-discharge cycles as the cells reach rated capacity. Complete those conditioning cycles before relying on the unit for continuous clinical sessions.
