Mindray PM7000 11.1V Replacement Battery 6800mAh Li-ion

Mindray PM7000 / Accutorr V / DPM Series — 11.1V Li-ion Replacement Battery (M05-010001-06)

This 11.1V, 6800mAh lithium-ion battery replaces the internal power cell in the Mindray PM7000, Accutorr V, DPM3, and DPM4 patient monitors, along with over 25 additional compatible models. It holds charge while the monitor runs disconnected from mains — during transport, bedside procedures, or power outages. Matches OEM part numbers M05-010001-06, LI23S003A, 0146-00-0099, and 115-018015-00 among others.

• PM7000 and DPM platform compatibility: These Mindray monitors share a common battery bay geometry, 11.1V three-cell Li-ion voltage rail, and the same BMS handshake protocol. One replacement cell covers the full platform without connector or firmware mismatch.
• Bench tested on actual hardware: We ran this cell through the PM7000's startup sequence and monitored BMS communication at full load. The protection circuit responded correctly to charge termination and discharge cutoff — no false fault codes generated during the test cycle.
• Post-swap self-test requirement: After installing this battery, allow the PM7000 to complete its full power-on self-test without interruption. Cutting power during the BMS verification cycle registers a false battery fault that persists across sessions until the device completes an uninterrupted reboot.

Why the PM7000 alarms low battery immediately after a confirmed full charge

The PM7000's BMS stores a capacity baseline from the previous cell and compares it against the new cell's first reported state-of-charge. A fresh Li-ion cell that hasn't completed a full charge-discharge cycle reports capacity figures the BMS flags as inconsistent with its stored threshold — triggering a low battery alarm even at 100% indicated charge. This isn't a fault with the replacement cell. Run one complete charge cycle through the monitor itself, not a standalone charger, to let the BMS recalibrate its baseline. After that cycle, the alarm clears and the indicator reads accurately.

Monitor won't power on after the replacement cell sat in storage

Li-ion cells self-discharge during storage. If the cell voltage drops below approximately 9V — the PM7000's BMS recovery threshold — the protection circuit opens and the monitor will not respond to the power button at all. The fix is to connect the monitor to AC mains first and leave it charging for at least 90 minutes before attempting to power on. This allows the charge IC to bring the cell back above the BMS recovery floor, typically around 10.5V, at which point the protection circuit closes and normal startup resumes.
