B.Braun Omni Infusion Pump Replacement Battery 24V 2700mAh

Up to 17% off
New arrival
From $94.99 USD $113.99
Shipping calculated at checkout.
Fits B.Braun Omni infusion pump, replaces OEM part numbers M0430060002, 20S-1P, 20HRLR17/50-1.
Delivers 24V at 2700mAh capacity, sustaining portable pump operation through medication delivery cycles.
Uses connector-based slot with fixed orientation; physical fit confirmed against OEM housing without modification.
Bench test shows standard Ni-MH BMS acceptance on first charge cycle with stable voltage ramp.
After installation, allow the pump to complete its power-on self-test sequence uninterrupted—medical devices verify new cell chemistry at startup, and stopping this cycle triggers false battery faults until 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.

B.Braun Omni Infusion Pump — 24V Ni-MH Replacement Battery (M0430060002)

This is a 24V, 2700mAh Ni-MH replacement battery for the B.Braun Omni infusion pump. It restores portable operation and patient mobility when the original cell has degraded past the pump's minimum charge threshold. Voltage and chemistry match OEM specifications: 24V Ni-MH, 64.8Wh.

  • Omni pump compatibility: The Omni's BMS handshake is tuned to 24V Ni-MH chemistry. This cell matches that voltage rail and connector pinout. Substituting a different voltage or chemistry will trigger a battery fault at startup and prevent infusion delivery.
  • Bench tested on actual hardware: We ran a full charge-discharge cycle and confirmed the BMS completed its self-test sequence without fault. The cell passed the pump's battery verification routine and held voltage within the Omni's operating window under simulated load.
  • First-cycle self-test protocol: After installation, let the pump complete its full power-on self-test without interrupting power. Medical BMS verification at startup reads the new cell's charge state and chemistry signature — cutting power mid-sequence logs a false battery fault that persists until the next complete reboot cycle.

Why the Omni pump alarms low battery immediately after a confirmed full charge

The Omni's charge IC applies a conservative acceptance threshold on the first cycle with a new Ni-MH cell. The cell may read full on the charger but the BMS has not yet built a charge-capacity baseline for it. Until one complete charge-discharge cycle is logged, the pump's battery monitor can flag a low threshold alarm even on a fully charged pack. Run one full cycle before relying on the battery for clinical use — the alarm clears once the BMS calibrates to the new cell's actual capacity.

Omni pump not completing boot sequence after battery sat in storage

Ni-MH cells self-discharge at roughly 1–2% per day in storage. A cell that has been sitting can drop below the Omni's BMS recovery threshold — typically around 18–20V on a 24V pack — and the pump will refuse to boot rather than risk operation on an unstable voltage rail. Connect the pump to mains power first and allow the charge IC to bring the cell up from its resting voltage before attempting a standalone boot. Once the cell reaches approximately 22V, the BMS will allow the boot sequence to proceed.

Frequently Asked Questions

The Omni pump shows a low battery alarm the moment I power it on, even though the replacement battery just came off a full charge — what's happening?

A new Ni-MH cell hasn't given the Omni's BMS enough data to set its charge-capacity baseline. The pump's battery monitor applies a conservative threshold on unfamiliar cells, and a single charge isn't enough to satisfy it. Run one complete charge-discharge cycle — charge to full, allow the pump to draw the cell down under normal load, then charge again. After that cycle the alarm clears and the BMS tracks the cell accurately.

The Omni pump shuts off mid-infusion during the first few days of use — is the battery faulty?

Not necessarily. Ni-MH cells under medical device load profiles deliver slightly lower sustained voltage in the first 8–10 cycles while the cell's internal resistance stabilises. The Omni's BMS cuts power at a fixed low-voltage floor, and a new cell can hit that floor earlier than a conditioned one will. Run several full charge-discharge cycles before clinical deployment. If shutdowns continue past cycle 10, check resting cell voltage after a full charge — it should hold above 25V at rest.

The charge indicator on the Omni pump never reaches 100% on the first charge with the new battery — should I keep charging it?

The Omni's charge IC limits acceptance current on an unrecognised Ni-MH pack until it completes a conditioning read. The indicator stops short of 100% because the IC hasn't confirmed the cell's full capacity yet — it's not a wiring or connector issue. Allow the pump to complete a full charge cycle on mains power without interruption, then discharge and recharge once more. After the second full cycle the charge IC recalibrates and the indicator reaches 100% correctly.
