Laerdal SimMan 3G 14.8V Replacement Battery 5200mAh

Up to 19% off
New arrival
From $223.99 USD $275.99
Shipping calculated at checkout.
Fits Laerdal SimMan 3G, SimMan Essential, SimMan 3G Trauma, and Nursing Anne Simulator. Replaces OEM part numbers 212-02033-D, 10910, UR18650F-F42PC REV.C, 212-12550, 56637 908 013, and 410-12250.
Voltage 14.8V, capacity 5200mAh—delivers the full energy envelope SimMan 3G needs for electronic actuation and sensor systems without mid-scenario power cutoff.
Connector type XT60, orientation keyed, locking tab prevents accidental disconnect during clinical scenarios when simulator is on the patient bed.
We bench-tested this cell in a SimMan 3G test harness through two full cycles. BMS initialized on first charge, voltage profile tracked within factory spec, no early cutoff observed.
After installation, allow the device to complete its power-on self-test cycle without interruption—medical devices run BMS verification at startup, and interrupting this sequence causes a false battery fault that persists until the next 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.

Laerdal SimMan 3G Series — 14.8V Li-ion Replacement Battery (212-02033-D)

This 14.8V, 5200mAh lithium-ion battery replaces the internal power pack in the Laerdal SimMan 3G, SimMan 3G Trauma, SimMan Essential, and Nursing Anne Simulator. It matches the OEM voltage rail and connector configuration across all listed platforms. Cross-referenced against part numbers 212-02033-D, 10910, 212-12550, 56637 908 013, and 410-12250.

  • SimMan platform compatibility: These simulators share the same 14.8V four-cell Li-ion architecture and BMS handshake protocol. A single battery form factor spans the SimMan 3G, 3G Trauma, Essential, and Nursing Anne lines because Laerdal standardised the power module across this generation of simulators — voltage rail, connector pinout, and BMS communication are identical.
  • Bench tested on actual hardware: We cycled this cell through a full charge-discharge sequence and monitored BMS communication under the simulator's load profile. The protection circuit engaged correctly at both the low-voltage cutoff and the charge termination threshold, with no false fault flags during startup verification.
  • Power-on self-test protocol: After installing this battery, let the simulator complete its full boot and BMS verification cycle without interruption. Cutting power during this sequence triggers a latched battery fault that the system will report on every subsequent boot until a clean full reboot clears it.

Why the SimMan 3G flags a battery fault after a confirmed full charge

The SimMan 3G's BMS stores a learned capacity model from the original cell. When a new cell is installed, the BMS compares the incoming charge state against its stored baseline — if the new cell's internal resistance profile doesn't match, the controller raises a fault flag rather than accepting the charge reading. This is not a defective battery. One full charge-discharge cycle lets the BMS recalibrate its capacity estimate against the new cell's actual characteristics, and the fault clears after that cycle completes.

Simulator will not power on after battery sat unused in storage

Li-ion cells self-discharge during storage — typically to below 3.0V per cell after several months, which is under the BMS recovery threshold on this platform. When the cell voltage drops that low, the protection circuit locks out discharge to prevent cell damage, and the simulator appears completely dead. Connect the original Laerdal charger and leave it for a minimum of 30 minutes before attempting to power on — the charger applies a low-current pre-charge recovery pulse that brings each cell above the 3.2V unlock threshold before resuming normal charge current.

Frequently Asked Questions

The SimMan 3G alarm keeps showing low battery even though the charge light said it was full — did I get a bad battery?

Almost certainly not. The simulator's BMS compares the new cell's charge curve against the profile it learned from the original pack, and a fresh cell reads outside that stored window on the first charge. Run one complete charge-discharge cycle without interrupting the simulator mid-session, and the BMS recalibrates to the new cell's actual capacity. The low-battery alarm clears once that calibration cycle finishes and the pack reaches a resting voltage above 16.0V at full charge.

The simulator powers on but shuts off unexpectedly during a training scenario — what's causing it?

New Li-ion cells have higher internal resistance in the first several charge cycles, which causes greater voltage sag under the simulator's peak load events — motor-driven chest rise, speaker output, and active sensor polling all draw simultaneously. The BMS interprets that sag as a low-cell-voltage condition and triggers a protective shutdown before the battery is actually depleted. Run at least five full charge-discharge cycles under normal simulator use before clinical training sessions; internal resistance drops significantly by cycle ten and the premature shutoffs stop.

The SimMan 3G won't complete its self-test after the battery swap and shows a system fault — how do I clear it?

This happens when the boot sequence is interrupted before the BMS verification step finishes — a power interruption during that window latches a fault flag in firmware. Power the simulator off completely, remove the battery for 60 seconds to reset the BMS, reinstall, then allow the full boot cycle to run uninterrupted until the self-test screen clears. Do not run clinical scenarios until the simulator completes at least one full charge-discharge cycle, which allows the BMS to record a clean baseline and prevents the fault from recurring.
