COMEN ND10 Monitor Replacement Battery 10.8V 2500mAh CMLI1X3N004A

Up to 19% off
New arrival
From $49.99 USD $61.99
Shipping calculated at checkout.
Fits COMEN ND10, ND10A, ND10C, ND10S patient monitors; replaces OEM battery CMLI1X3N004A.
10.8V, 2500mAh capacity delivers full charge cycles on the ND10 platform without voltage sag during vital sign acquisition.
Connector seats vertically into the monitor chassis with a single locking tab; push until the tab clicks fully home.
Bench testing showed the BMS accepted charge within specification; no cutoff anomalies on first cycle at nominal load.
Allow the ND10 to complete its full power-on self-test without interruption after installation — medical devices verify battery handshake at startup, and interrupting this sequence triggers a false fault that only clears 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.

COMEN ND10 Monitor Series — 10.8V Li-ion Replacement Battery (CMLI1X3N004A)

This is a 10.8V, 2500mAh Li-ion battery built to the CMLI1X3N004A specification. It fits the COMEN ND10, ND10A, ND10C, and ND10S patient monitors, along with additional variants in the ND10 series. These monitors run continuous vital signs surveillance — heart rate, SpO2, NIBP, and temperature — so consistent, uninterrupted power is critical.

  • ND10 series platform compatibility: All ND10 variants share the same voltage rail, physical connector, and BMS handshake protocol, which is why a single cell chemistry at 10.8V covers the full model range without firmware or hardware modification.
  • Bench tested on actual hardware: We ran this battery through the ND10's power-on self-test sequence and confirmed the BMS communicates state-of-charge correctly to the monitor's charge IC. The cell passed capacity verification within the device's accepted threshold window.
  • Post-installation self-test protocol: After fitting this battery, allow the ND10 to complete its full power-on self-test without interruption. The monitor's BMS verification routine runs at startup — cutting power during this sequence triggers a persistent battery fault flag that won't clear until the next clean reboot.

Why the ND10 shows a battery fault after a confirmed full charge

The ND10 monitor uses a BMS threshold calibrated to the original cell's chemistry profile. A fresh replacement cell hasn't yet built a charge history for the device to reference, so the monitor's charge IC applies a conservative acceptance window on the first cycle. This can flag an alert even when the cell is genuinely full. One complete charge-to-discharge-to-charge cycle lets the BMS establish a baseline and clears the mismatch. Do not place the device in clinical rotation until this cycle is complete.

ND10 not completing boot sequence on new battery after storage

Li-ion cells self-discharge during storage. If the cell voltage drops below approximately 9.0V, the ND10's BMS will refuse to initiate a boot sequence — the device appears dead even when connected to a charger. In this state, leave the battery connected to the dock or charger for at least 60 minutes before attempting to power on. The charge IC needs to bring the cell above the BMS recovery threshold before it will pass control to the monitor's startup sequence. If the device still won't boot after that window, check that charger output voltage is stable at the rated level before assuming a faulty cell.

Frequently Asked Questions

The ND10 is alarming low battery within minutes of a fully charged replacement — what's happening?

This is a BMS calibration mismatch, not a faulty cell. The ND10's charge IC compares incoming state-of-charge data against a profile built on the original cell's chemistry, and a new cell won't match that profile on its first cycle. Run one full charge-discharge-recharge cycle on the replacement before trusting the battery indicator. The low battery alarm will stop triggering incorrectly once the BMS has a valid baseline for the new cell.

The charge indicator on the ND10 won't reach 100% on the first charge — is the replacement cell defective?

It's not defective. The ND10's charge IC applies a conservative current limit on the first charge of any new cell, which means the charge termination point sits slightly below the full-capacity threshold until the cell's internal resistance profile is logged. This is normal first-cycle behaviour across medical-grade Li-ion equipment. Let the battery charge uninterrupted to completion, then run one discharge cycle, and the indicator will read accurately on the following charge.

The ND10 is shutting off unexpectedly mid-use even though the battery shows adequate charge — what causes this?

New Li-ion cells carry higher internal resistance for the first several cycles, and the ND10's continuous monitoring load — running SpO2, NIBP, and display simultaneously — pulls enough current to trigger the BMS undervoltage cutoff before the gauge reads empty. This is a voltage sag issue, not a capacity issue. The cell's internal resistance drops after 8–10 full cycles, which raises the sag floor and stops the unexpected cutoffs. Track the shutdown frequency across the first ten cycles — if it doesn't improve after that, check the resting voltage immediately after removal; it should read above 10.0V.
