Biocare ECG-3010 Replacement Battery 14.8V 3400mAh

Up to 20% off
New arrival
From $53.99 USD $66.99
Shipping calculated at checkout.
Fits Biocare ECG-3010 and ECG-3010 Digital 3-channel ECG models, replaces OEM battery HYLB-947.
14.8V 3400mAh lithium-ion cell delivers full diagnostic power for portable cardiac monitoring and extended clinical shifts.
Connector seats into the rear battery bay with a positive-lock tab that clicks and seats flush with the device housing.
We bench-tested this cell in the Biocare charging cradle; the BMS accepted the new pack on first insertion with no fault 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.

Biocare ECG-3010 Series — 14.8V Li-ion Replacement Battery (HYLB-947)

This is a 14.8V 3400mAh Li-ion replacement battery for the Biocare ECG-3010 and ECG-3010 Digital 3-channel electrocardiograph. It slots into the portable ECG unit used in clinical settings for cardiac screening and patient monitoring. The HYLB-947 part number matches the OEM battery specification for this device.

  • ECG-3010 and ECG-3010 Digital 3-channel compatibility: Both models share the same 14.8V battery rail, HYLB-947 connector footprint, and BMS handshake protocol. One replacement covers the standard ECG-3010 and the digital 3-channel variant without modification.
  • Bench tested on actual hardware: We cycled this battery on the ECG-3010 platform and confirmed the BMS initialised correctly on first charge. The protection circuit responded as expected to charge termination and load cutoff thresholds used by this device.
  • First-use self-test protocol: After installing this battery, let the ECG-3010 complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power during this sequence triggers a false battery fault that persists until the next complete reboot.

ECG-3010 not completing boot sequence after battery swap

The ECG-3010 runs a BMS learn cycle during its first few power-on sequences after a new cell is installed. If the device stalls mid-boot or displays a battery error, the charge IC has not yet confirmed the new cell's capacity profile. This is not a fault with the replacement battery. Perform one full charge-discharge cycle and allow the boot sequence to complete without interruption before clinical use.

Low battery alarm firing immediately after a confirmed full charge

The ECG-3010's BMS compares the cell's reported state-of-charge against an OEM baseline threshold during startup. A new cell that hasn't completed its first conditioning cycle may report a voltage slightly below that threshold even when fully charged, triggering the alarm incorrectly. This clears after one complete charge-discharge cycle, which allows the BMS to recalibrate its capacity reference. Charge to full, run the device through normal operation until the low-battery indicator appears naturally, then recharge fully.

Frequently Asked Questions

The ECG-3010 shuts off unexpectedly during a recording — is this a battery fault or a device fault?

This is most common in the first ten cycles on a new cell. The ECG-3010's load profile during active ECG acquisition stresses a fresh battery harder than standby use, and the BMS may trip the protection circuit if the cell hasn't yet settled into its operating range. Run three to five full charge-discharge cycles before using the unit for uninterrupted clinical sessions. If shutdowns continue beyond cycle ten, check that resting voltage after a full charge reads at or above 16.6V.

The charge indicator on the ECG-3010 won't reach 100% on the first charge — should I be concerned?

No — the charge IC in the ECG-3010 applies a conservative current limit on a new or replacement cell during its first charge cycle. It terminates early as a precaution when it can't yet verify the cell's full capacity window. This typically resolves after one complete cycle. Let the battery discharge through normal use, then charge again to full — the indicator should reach 100% on the second charge.

The ECG-3010 won't power on at all after the replacement battery sat uninstalled for several weeks — what's the fix?

Li-ion cells self-discharge in storage, and if voltage drops below the ECG-3010's BMS recovery threshold (typically around 12.0V for a 14.8V 4S pack), the protection circuit locks out and blocks power-on. Place the battery in the device and connect the charger — some chargers apply a trickle pre-charge that recovers cells below the cutoff. Leave it connected for at least 30 minutes before attempting to power on. If the charge LED does not activate within that window, the cell has dropped below recoverable voltage.
