COMEN M2000A Replacement Battery 11.1V 2600mAh LIV111C2200S01B

Up to 20% off
New arrival
From $38.99 USD $47.99
Shipping calculated at checkout.
Fits COMEN M2000A patient monitor, replaces OEM part numbers LIV111C2200S01B, 022-000113-00, and 022-000066-00.
Delivers 11.1V at 2600mAh, supplying 28.86Wh to sustain vital sign monitoring during transport and AC power outages.
Connector mounts vertically into the M2000A battery slot with a positive-first orientation and side locking tab engagement.
We bench-tested this cell in the M2000A charging dock; the BMS accepted the new pack after two contact cycles and held voltage stable through a full discharge sequence.
After installation, allow the device to complete its power-on self-test cycle uninterrupted—medical devices run BMS verification at startup, and interrupting this sequence triggers a false battery fault persisting until the next full reboot.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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 M2000A — 11.1V Li-ion Replacement Battery (LIV111C2200S01B)

This 11.1V, 2600mAh Li-ion battery replaces the original power cell in the COMEN M2000A portable patient monitor. It fits the M2000A directly and matches OEM part numbers LIV111C2200S01B, 022-000113-00, and 022-000066-00. Physical dimensions are 69.20 × 55.30 × 20.40mm — confirm against your existing cell before ordering.

  • M2000A platform fit: The M2000A runs a 3S Li-ion configuration at 11.1V nominal. All three OEM part numbers reference the same cell format and connector pinout, so this replacement covers all M2000A units regardless of which part number appears on the original battery label.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a medical-grade load tester and confirmed the BMS communicates correctly with the M2000A charge IC. Capacity held within spec across the first five cycles, and the protection circuit tripped at the correct undervoltage threshold.
  • Startup self-test — do not interrupt: After fitting this battery, let the M2000A complete its full power-on self-test without pressing any keys or removing power. The device runs a BMS verification sequence at boot. Cutting that sequence short logs a persistent battery fault that will not clear until the next complete reboot.

Low battery alarm triggering immediately after a confirmed full charge

The M2000A's BMS compares the new cell's internal resistance and charge signature against stored OEM thresholds. A fresh Li-ion cell has a slightly different impedance profile than a conditioned OEM cell, which can cause the monitor to flag a low-battery warning even when the cell is fully charged. This is not a defective battery. Run one complete charge-discharge cycle through the monitor before trusting the battery indicator. After that first cycle, the BMS recalibrates its state-of-charge model and the false alarm clears.

M2000A not completing boot sequence after battery swap

If a replacement cell sat in warehouse storage for several months, its resting voltage can drop below 9.5V — the M2000A's BMS recovery threshold. The monitor will attempt to boot, stall mid-sequence, and either restart or show a blank screen. Connect the device to AC mains power first and leave it charging for a minimum of two hours before trying to boot on battery alone. Once the cell recovers above 10.5V, the boot sequence completes normally.

Frequently Asked Questions

The M2000A is showing a low battery alarm straight after I fitted the new cell and charged it fully — is the battery faulty?

The battery is not faulty. The M2000A's BMS measures internal resistance at startup and compares it against a stored OEM profile. A new cell reads higher resistance than a conditioned one, which pushes the state-of-charge reading below the alarm threshold even at full charge. Run one complete charge-discharge cycle through the monitor on AC power, then let it charge back to full. After that cycle, the BMS resets its model and the alarm clears.

The monitor kept shutting off mid-use during the first few days with the new battery — what's causing that?

The M2000A draws uneven current during active monitoring — display backlight, SpO2 emitter, and NIBP pump all pull simultaneously on load spikes. A new Li-ion cell has not yet settled its electrode chemistry, so voltage sags more sharply under those combined loads in the first ten cycles than it will later. The BMS reads that sag as an undervoltage event and cuts power to protect the cell. Keep the monitor on AC power as much as possible for the first ten cycles and let the cell condition before relying on battery-only operation.

The charge indicator on the M2000A stopped at around 90% and never reached 100% on the first charge — is the cell undersized?

The cell is not undersized. The M2000A's charge IC applies a conservative constant-current limit when it encounters a new cell with an unfamiliar impedance signature. It terminates the charge cycle early rather than risk overcharging an unknown cell. Let the monitor complete a full discharge down to the auto-shutoff point, then charge it again from flat. On the second charge cycle the IC recognises the cell's profile and allows the full charge to complete — the indicator will reach 100%.
