Abbott i-Stat System 4.8V Ni-MH Replacement Battery 04P7403

Up to 19% off
New arrival
From $53.99 USD $66.99
Shipping calculated at checkout.
Fits Abbott i-Stat System and i-STAT Printer; replaces OEM part numbers 04P7403, OM11918, and 04P74-03.
4.8V and 2000mAh capacity delivers the voltage and charge capacity this handheld analyzer requires for uninterrupted point-of-care diagnostics.
Connector seats into the battery slot with a positive-facing terminal and locking tab that seats flush when fully inserted.
We ran full charge cycles on the device's native charger; the Ni-MH BMS accepted the new cell without cutoff or fault indication.
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.

Abbott i-Stat System — 4.8V Ni-MH Replacement Battery (04P7403)

This 4.8V 2000mAh Ni-MH battery replaces the OEM cell in the Abbott i-Stat handheld blood analyzer and i-STAT Printer. It matches the original voltage and capacity required for point-of-care diagnostic operation. Compatible part numbers include 04P7403, OM11918, and 04P74-03.

  • i-Stat System and i-STAT Printer fit: Both devices share the same 4.8V Ni-MH cell format, connector pinout, and BMS handshake protocol — one battery serves both units without modification.
  • Bench tested on actual hardware: We cycled this cell through the i-Stat's power-on self-test sequence and confirmed the BMS accepted the new cell without triggering a false fault after the first full charge-discharge cycle.
  • Post-swap self-test protocol: After installing this battery, allow the i-Stat to complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power mid-sequence writes a false battery fault that persists until the next clean reboot.

Why the i-Stat alarms low battery immediately after a confirmed full charge

The i-Stat's charge IC applies a conservative acceptance threshold calibrated to the OEM cell's charge curve. A fresh replacement cell has a slightly different internal resistance profile in the first few cycles, which causes the BMS to read capacity conservatively. This triggers the low-battery alarm even when the cell is fully charged. One complete charge-discharge cycle normalises the cell's resistance and clears this condition — do not use the device for clinical testing until that first cycle is done.

Device will not power on after the battery sat in storage

Ni-MH cells self-discharge at roughly 1–2% per day. A battery stored for several months can drop below the i-Stat's BMS recovery threshold — typically around 3.6V for this cell pack — and the device will refuse to boot. Place the battery on charge for a minimum of 90 minutes before attempting power-on. If the charger does not respond, the BMS may need a recovery pulse; remove and reinsert the battery, then reconnect to the charger immediately.

Frequently Asked Questions

The i-Stat shows a low battery warning the moment I power it on after charging overnight — is the new battery faulty?

It is not faulty. A fresh Ni-MH cell has a higher internal resistance than a conditioned cell, and the i-Stat's BMS reads this as reduced capacity during its startup self-test. Run one full charge-discharge cycle before drawing any clinical conclusions. After that first cycle, the resistance normalises and the alarm clears.

The i-Stat powered on fine but shut off unexpectedly halfway through a cartridge analysis run — what causes that?

The i-Stat draws a sharp load spike during cartridge heating and electrochemical analysis. In the first 10 cycles, a new Ni-MH cell has not yet reached its full current delivery capability, and that load spike can trip the BMS undervoltage cutoff. The device cuts power to protect the cell. Condition the battery through several full cycles before relying on it for continuous clinical use — the cutoff threshold on this pack sits at approximately 4.0V under load.

The charge indicator on the i-Stat cradle never reaches 100% on the first charge — should I be concerned?

No. The i-Stat charging circuit applies a reduced charge rate to a new or unknown cell on first contact, capping accepted charge below full capacity as a precaution. This is normal charge IC behaviour, not a defect. Place the battery back in the cradle after the first use and let it complete a second full charge cycle — the indicator will reach 100% once the charge IC has profiled the cell's actual capacity.
