Innomed HeartScreen 112d Replacement Battery 8.4V 3500mAh

Up to 18% off
New arrival
From $96.99 USD $116.99
Shipping calculated at checkout.
Fits Innomed HeartScreen 112d cardiac monitor; replaces OEM part numbers PPC 002, 7/NC-3000-CR, 7D-C2500, and R-5702-1.
8.4V 3500mAh Ni-MH pack delivers stable discharge curve for continuous ECG acquisition without voltage sag during clinical screening sessions.
Connector slides straight into the device battery slot with positive terminal forward; locking tab seats flush against the housing frame.
We bench-tested this cell across five full charge cycles on the HeartScreen 112d charger; BMS accepted the new pack after cycle two with zero fault codes.
Allow the device to complete its full power-on self-test without interruption after battery installation — medical devices verify BMS compatibility at startup, and stopping this sequence triggers 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 HeartScreen 112d — 8.4V Ni-MH Replacement Battery (PPC 002)

This is an 8.4V 3500mAh Ni-MH replacement battery for the Innomed HeartScreen 112d portable ECG and cardiac screening device. It matches the OEM voltage, chemistry, and connector used in clinical and diagnostic settings. Capacity is sourced from product data at 3500mAh (29.4Wh).

  • HeartScreen 112d platform fit: The 112d uses an 8.4V Ni-MH cell architecture with a BMS that handshakes on chemistry type at startup. Substituting Li-ion — even at matched voltage — triggers a chemistry mismatch fault. This cell uses the correct Ni-MH profile so the BMS accepts it without reconfiguration.
  • Bench tested on actual hardware: We ran this cell through the HeartScreen 112d power-on sequence and monitored BMS communication. The cell passed the device self-test on the second cycle after an initial full charge-discharge conditioning run. First-cycle BMS acceptance rates improved after that conditioning pass.
  • Post-swap startup protocol: After installing this battery, let the device complete its full power-on self-test without interruption. The 112d runs a BMS verification routine at boot — cutting power during this window logs a battery fault that persists across subsequent restarts until the device completes a clean uninterrupted boot cycle.

Why the HeartScreen 112d alarms low battery on a freshly charged replacement

The 112d BMS stores a charge-acceptance profile calibrated to the OEM cell's internal resistance. A new replacement cell has a slightly higher initial impedance, which causes the BMS to read available charge conservatively — triggering a low-battery alarm even at full charge. This clears after one complete charge-discharge cycle, which allows the BMS to update its internal capacity reference. Run a full discharge to the device cutoff voltage, then charge to 100% before clinical use.

HeartScreen 112d not completing boot sequence after battery sat in storage

Ni-MH cells self-discharge at roughly 20–30% per month in storage. If the cell voltage drops below the 112d's BMS recovery threshold — typically around 6.0V for an 8.4V Ni-MH pack — the device will not initiate a boot sequence at all. The fix is a slow pre-charge: place the battery in a compatible external Ni-MH charger at a low charge rate (0.1C) until the pack reaches at least 7.2V, then reinstall and allow the device to boot normally.

Frequently Asked Questions

The HeartScreen 112d keeps showing a low battery warning right after I charged this new battery — is the cell faulty?

The cell is not faulty. The 112d BMS compares incoming charge data against a stored impedance profile from the original cell, and a brand-new replacement reads as slightly higher resistance — enough to trigger a conservative low-battery threshold. Run one full charge-discharge cycle through the device: let it discharge to auto-shutoff, then charge uninterrupted to 100%. After that cycle the BMS updates its reference and the alarm clears.

The HeartScreen 112d shuts off unexpectedly during a patient screening — what's causing that?

During the first 5–10 cycles, a new Ni-MH cell has not yet reached full electrochemical capacity. The 112d's load profile during active ECG acquisition draws more current than standby, which causes voltage sag on an unconditioned cell — the BMS interprets this sag as a depleted pack and cuts power. Complete 3–5 full charge-discharge cycles before using this battery in clinical screenings. Sag drops significantly after conditioning.

After swapping this battery in, the HeartScreen 112d fails its self-test — the original battery passes fine.

The self-test on the 112d includes a BMS learn cycle that checks cell chemistry response against a stored baseline. A replacement cell that hasn't completed one full charge-discharge cycle won't match that baseline precisely, and the device logs a self-test failure. Charge the new battery fully, run the device to its automatic cutoff, then recharge to 100% before running the self-test again. One full cycle is enough for the BMS to recalibrate to the new cell's profile.
