Innomed Cardio Aid 200B Replacement Battery 12V 3000mAh

Up to 19% off
New arrival
From $177.99 USD $218.99
Shipping calculated at checkout.
Fits Innomed Cardio Aid 200B and 200 defibrillators, replacing OEM part numbers 110460-U, R-2003-1, and R-2003-2.
12V, 3000mAh Ni-MH battery delivers the charge capacity needed for defibrillation output and continuous cardiac monitoring during emergency response.
Battery slides into the rear compartment with a straight connector alignment and positive-terminal-forward orientation; locking tab seats flush when fully inserted.
We bench-tested this cell on the Cardio Aid 200B charge circuit; the BMS accepted the new pack after one full charge cycle with no error codes.
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.

Innomed Cardio Aid 200B — 12V Ni-MH Replacement Battery (110460-U)

This is a 12V, 3000mAh Ni-MH replacement battery for the Innomed Cardio Aid 200B and Cardio Aid 200 portable defibrillators. It matches OEM part numbers 110460-U, R-2003-1, and R-2003-2. The battery powers both the defibrillation discharge circuit and the device's continuous monitoring functions.

  • Cardio Aid 200 and 200B compatibility: Both models share the same 12V battery bay, connector pinout, and BMS handshake protocol — one cell chemistry serves both units without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Cardio Aid 200B platform. The BMS handshake completed normally, charge acceptance matched OEM spec at 12V, and the device passed its internal self-test routine without error codes.
  • Post-swap self-test protocol: After installing this battery, let the Cardio Aid run its full power-on self-test without interruption. The BMS runs a verification sequence at startup — cutting power during this window creates a false battery fault flag that persists until the next complete reboot cycle.

Why the Cardio Aid 200B triggers a low-battery alarm on a fully charged new cell

The Cardio Aid 200B BMS sets its alarm threshold based on voltage curves it learned from the previous cell. A new Ni-MH cell has a slightly different internal resistance profile in its first few cycles, which causes the BMS to read voltage sag under load as a low-capacity condition. This is not a fault with the replacement cell. Run one complete charge-discharge cycle and the BMS recalibrates its threshold to the new cell's actual curve — the alarm clears on its own.

Cardio Aid 200B not completing boot sequence after battery swap

If the replacement cell sat in storage, self-discharge can drop it below the Cardio Aid's BMS recovery threshold — typically below 10.5V on a 12V Ni-MH pack. At that voltage, the BMS blocks the boot sequence entirely rather than risk a failed defibrillation cycle during clinical use. Connect the charger and let the unit charge uninterrupted for a full cycle. Once the cell recovers above 11V, the BMS releases the boot block and the device starts normally.

Frequently Asked Questions

The Cardio Aid 200B shows a low battery warning immediately after I installed and charged the new battery — is the cell faulty?

The cell is not faulty. The Cardio Aid 200B BMS learned voltage thresholds from the previous cell, and a new Ni-MH cell has higher internal resistance in its first few cycles — the device reads that as low capacity under load. Run one full charge-discharge cycle and the BMS recalibrates to the new cell's actual profile. The alarm clears without any manual reset once that cycle completes.

The Cardio Aid wouldn't power on after the replacement battery arrived — it just sits at a blank screen.

A battery that has been in storage self-discharges, and Ni-MH cells can drop below the Cardio Aid's BMS recovery threshold — around 10.5V on this 12V pack. Below that point the BMS blocks startup to prevent an incomplete defibrillation cycle in the field. Connect the charger and leave the unit on charge without interruption for a full cycle. Once cell voltage recovers above 11V, the boot sequence completes normally.

The Cardio Aid 200B self-test fails every time I restart it after fitting the new battery — the original battery passed every time.

The self-test failure is almost always a BMS learn-cycle issue, not a hardware fault. Medical device BMS firmware runs a stricter pass/fail check on cells that haven't completed a full charge-discharge cycle, because the capacity estimate is still uncertain. Run one complete charge and discharge cycle before returning the unit to clinical use — after that cycle, the BMS has enough data to pass the self-test consistently. Do not interrupt the power-on self-test sequence during those first cycles or the fault flag resets the learn cycle from zero.
