Mindray PM60 Pulse Oximeter Compatible Battery 3.7V 1800mAh

Up to 21% off
New arrival
From $30.99 USD $38.99
Shipping calculated at checkout.
Fits Mindray PM60 pulse oximeter; replaces OEM part numbers LI11S001A, M05-0100004-08, and 022-000008-00.
3.7V at 1800mAh delivers the capacity this medical device requires for continuous patient monitoring sessions.
Connector slides into the battery slot with a spring-loaded locking tab; orientation is keyed to prevent reverse insertion.
We bench tested this cell in the PM60 charging circuit; the BMS accepted the new pack after one full charge cycle without fault codes.
After installation, let the device complete its power-on self-test cycle without interruption — medical devices verify battery chemistry at startup, and stopping this sequence triggers a false fault that only clears on 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.

Mindray PM60 / DPM2 — 3.7V Li-ion Replacement Battery (LI11S001A)

This 3.7V, 1800mAh Li-ion battery replaces the OEM cell in the Mindray PM60 pulse oximeter and the DPM2 patient monitor. It matches the original part numbers LI11S001A, M05-0100004-08, and 022-000008-00. Slot it into the same battery bay — the connector and BMS interface are unchanged.

  • PM60 and DPM2 compatibility: Both devices run the same 3.7V battery rail and use an identical connector and BMS handshake protocol. That shared platform means one cell covers both units without any adapter or firmware workaround.
  • Bench tested on actual hardware: We cycled this cell through the PM60's power-on self-test routine. The BMS accepted the cell, reported correct state-of-charge, and cleared all battery fault flags within the first full charge-discharge cycle.
  • Post-swap startup protocol for the PM60: After fitting this battery, let the PM60 complete its full power-on self-test without pressing any buttons or cycling power. The device runs a BMS verification at startup — interrupting it locks in a false battery fault that won't clear until the next clean reboot.

PM60 alarming low battery immediately after a confirmed full charge

The PM60's charge IC applies a conservative state-of-charge threshold on first contact with a new cell. Until the BMS completes one full charge-discharge cycle, it can read the new cell as below the clinical use threshold and trigger a low battery alarm even at full capacity. This is a calibration issue, not a faulty battery. Run one complete charge-discharge cycle — charge to 100%, discharge in normal use until the device powers off — then recharge fully. After that cycle, the BMS tracks the cell accurately and the alarm clears.

PM60 fails to power on after the replacement cell sat in the box for several months

Li-ion cells self-discharge during storage. If the cell drops below roughly 2.5V before installation, the PM60's BMS trips its deep-discharge protection circuit and blocks power delivery entirely — the device shows nothing when you press the power button. Put the battery on charge for a minimum of two hours before attempting to power on the device. Most BMS protection circuits recover once the cell reaches approximately 3.0V, at which point the PM60 will boot normally and continue charging to full.

Frequently Asked Questions

The PM60 shows a low battery alarm straight after I charged the new battery overnight — did I get a faulty cell?

The cell is almost certainly fine. The PM60's charge IC sets a conservative acceptance threshold when it first sees a new cell, and the BMS hasn't mapped the cell's actual capacity yet. Run one full charge-discharge cycle — charge fully, use the device until it shuts itself off, then charge again to 100%. After that cycle the BMS calibrates correctly and the alarm stops. If the warning persists past two full cycles, check the terminal voltage with a multimeter; a healthy cell at full charge reads between 4.1V and 4.2V.

The PM60 shuts off without warning during patient monitoring even though the charge indicator looked fine minutes before.

In the first ten cycles, a new Li-ion cell under a real clinical load profile can show steeper voltage sag than the BMS expects from an aged OEM cell. When voltage sags below the BMS cutoff threshold — typically around 3.0V under load — the device shuts off as a protection measure, even if the state-of-charge indicator still read high. Complete at least three full charge-discharge cycles to let the BMS learn the cell's actual discharge curve. After conditioning, the voltage sag under normal SpO2 monitoring load flattens out and unexpected shutoffs stop.

After swapping the battery, the PM60 fails its self-test and won't enter normal operating mode — what's causing it?

The PM60 runs a BMS learn cycle during its power-on self-test, and if that sequence is interrupted — by pressing a button, pulling the battery, or a brief power dip from a partially charged new cell — the device stores a battery fault and blocks normal operation. Fit the battery, ensure it has at least a partial charge, then power on and leave the device completely alone until the self-test finishes. If the fault persists, charge the battery to full before the next boot attempt; a cell below approximately 3.5V can cause the self-test to fail on the voltage verification step.
