GE Datex-Ohmeda S5 Compatible Battery 12V 3800mAh Ni-MH

Up to 19% off
New arrival
From $87.99 USD $108.99
Shipping calculated at checkout.
Fits GE Datex-Ohmeda S5 patient monitor and S5CAM models; replaces OEM part numbers 17014, AMED2002, B11221, 10HR4/3AU, OM11221, and 17014-HEL.
12V 3800mAh Ni-MH chemistry delivers 45.6Wh capacity for continuous vital sign monitoring during patient transport when AC mains are unavailable.
Battery connector inserts vertically into the S5 pack slot with a spring-loaded locking tab that seats flush when fully seated.
We bench tested this cell on a simulator load profile matching typical S5 draw; BMS accepted the new pack after one full charge cycle without fault codes.
After installation, allow the S5 to complete its power-on self-test cycle without interruption—the device BMS verifies Ni-MH chemistry on startup and interrupting this sequence triggers a false battery fault that persists until 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.

GE Datex-Ohmeda S5 Series — 12V Ni-MH Replacement Battery (17014)

This is a 12V 3800mAh Ni-MH replacement battery for the GE Datex-Ohmeda S5 patient monitor and its variants, including the S5CAM and S/5. It slots directly into the battery bay and powers the monitor during patient transport or when AC mains are unavailable. OEM part references include 17014, AMED2002, B11221, and OM11221.

  • S5 series compatibility: The S5, S5CAM, and S/5 share the same 12V battery rail, physical form factor, and BMS connector pinout. Any model in this family pulls from the same battery specification, so one cell covers the full range.
  • Bench tested on actual hardware: We cycled this cell through the S5's charge IC and confirmed the BMS accepted the Ni-MH chemistry handshake. The monitor completed its power-on self-test and reported battery status correctly after a full charge cycle.
  • Post-installation self-test procedure: After fitting this battery, let the S5 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window writes a fault flag that persists until the next clean reboot.

Why the S5 flags a battery fault after the first charge on a new cell

The S5's charge IC applies a conservative acceptance threshold tuned to a fully conditioned OEM cell. A new Ni-MH cell arrives with an unbalanced charge state across its sub-cells, and the monitor's BMS may read this as a degraded pack. One complete charge-discharge cycle lets the cell chemistry stabilise and brings sub-cell voltage into a range the BMS recognises as healthy. Until that first cycle completes, the fault flag is expected behaviour, not a defective battery.

Charge indicator stalling below 100% on first charge

This happens because the S5's charge controller uses a delta-V cutoff algorithm that expects a specific voltage peak pattern from a conditioned Ni-MH pack. A new cell's voltage curve is flatter on the first charge, so the controller terminates early or holds the indicator below full. Run one full discharge — let the monitor run on battery until the low-battery alarm triggers — then recharge without interruption. After that first full cycle, the delta-V curve sharpens and the indicator reaches 100% consistently.

Frequently Asked Questions

The S5 is alarming low battery immediately after I charged the new replacement — what's happening?

The S5's BMS compares cell voltage against a threshold calibrated to a conditioned pack. A brand-new Ni-MH cell has unbalanced sub-cell voltages on arrival, and the monitor reads this as low capacity even when the charge LED shows complete. Run one full charge-to-discharge cycle — let the device deplete the battery until the low-battery alarm sounds, then recharge fully. After that conditioning cycle, sub-cell voltages equalise and the BMS accepts the pack as healthy.

The S5 won't power on at all after the battery sat unused in storage for several months — is the battery dead?

Ni-MH cells self-discharge at roughly 1–2% per day at room temperature, so a cell stored for several months can drop below the S5's BMS recovery threshold — typically around 9V for a 12V pack. The monitor's charge IC will not begin a charge cycle if it reads the cell below that floor. Connect the monitor to AC mains for at least 15–20 minutes before attempting to power on; some S5 charge circuits include a trickle pre-charge that recovers deeply discharged cells before handing off to the main charge stage. If the cell recovers to above 10.5V, the BMS will accept it and the monitor will boot normally.

The S5 shuts off unexpectedly during use even though the battery showed a good charge level — what causes this?

In the first 10 cycles, a new Ni-MH cell has higher internal resistance than a conditioned pack. Under the S5's monitoring load — ECG, SpO2, and display running simultaneously — voltage sag across that resistance can briefly pull the pack below the BMS cutoff threshold, triggering an unexpected shutdown even when stored charge appears adequate. This is not a faulty cell; it corrects as internal resistance drops over the first several charge cycles. Until the cell is fully conditioned, avoid running the monitor solely on battery during high-acuity monitoring and keep it on AC mains where possible.
