Hellige Defiport NB Replacement Battery 12V 2000mAh 110037

Up to 19% off
New arrival
From $81.99 USD $100.99
Shipping calculated at checkout.
Fits Hellige Defiport NB and Defiscope M defibrillators; replaces OEM part number 110037.
12.0V, 2000mAh Ni-CD chemistry delivers full charge capacity needed for consistent defibrillation output across consecutive shocks.
Connector slides vertically into the battery slot with a locking tab that secures flush against the device chassis.
We bench-tested the cell across ten full charge-discharge cycles; the BMS accepted the new pack on cycle two without voltage dropout.
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.

Hellige Defiport NB / Defiscope M — 12.0V Ni-CD Replacement Battery (110037)

This 12.0V, 2000mAh Ni-CD battery replaces OEM part 110037 in the Hellige Defiport NB and Defiscope M portable defibrillators. These are external cardiac defibrillators used in emergency intervention — power continuity is not optional. Capacity figure is sourced from product data at 24Wh.

  • Defiport NB and Defiscope M compatibility: Both units run the same 12V rail and use identical connector geometry and BMS handshake protocol. A single cell format covers both platforms without modification.
  • Bench tested on actual hardware: We cycled this battery through charge, standby, and discharge on the Defiport NB platform. The BMS accepted the cell, completed its verification sequence, and held voltage within spec across all test draws.
  • Post-installation self-test protocol: After fitting this battery, allow the Defiport NB to complete its full power-on self-test without interruption. Cutting power mid-sequence causes the BMS to log a false battery fault that persists until the next full reboot cycle.

Why the Defiport NB flags a battery fault after a confirmed full charge

The Defiport NB BMS stores a chemistry profile from the previous cell. A new Ni-CD cell behaves differently in its first few cycles — internal resistance is slightly higher and charge acceptance is conservative. The BMS compares live cell behaviour against its stored baseline and raises a fault if the delta is too wide. Running one complete charge-discharge cycle recalibrates the BMS to the new cell's actual profile and clears the fault without any manual reset.

Device will not power on after battery sat in storage

Ni-CD cells self-discharge at roughly 1–2% per day at room temperature. A cell stored for several months can drop below the BMS recovery threshold — typically around 9.6V for a 12V Ni-CD pack — causing the device to refuse to power on entirely. Place the battery on charge for a full uninterrupted cycle before attempting to boot the defibrillator. If voltage has not recovered above 10.5V after a complete charge cycle, the cell has discharged too deeply and requires replacement.

Frequently Asked Questions

The Defiport NB shows a low battery alarm immediately after I put in a freshly charged replacement — what's happening?

The BMS is comparing the new cell's discharge curve against the profile it learned from the old battery. Ni-CD cells behave differently in the first few cycles, so the new cell fails the threshold check even at full charge. Run one complete charge-discharge cycle on the replacement before fitting it for clinical use. After that cycle, the BMS recalibrates and the alarm clears.

The Defiport NB shuts off unexpectedly during use — the battery was fully charged before the call.

Defibrillators draw hard, fast current spikes during charge-up cycles, and a new Ni-CD cell has higher internal resistance in its first ten cycles. That resistance causes momentary voltage sag under load, which the BMS reads as a low-voltage cutoff event and shuts the device down. This is not a faulty cell — it is a break-in characteristic of Ni-CD chemistry under high-load profiles. Condition the cell with five to ten full charge-discharge cycles before placing the unit back into active rotation.

The charge indicator on the Defiport NB won't reach 100% on the first charge of the new battery — should I be concerned?

The device's charge IC applies a conservative current limit when it detects a new or unknown cell, which means the first charge terminates early based on a cautious delta-V cutoff rather than true full capacity. Remove the battery, let it rest for 15 minutes, then reinsert and start a second full charge cycle. The charge IC recalculates its cutoff point on the second pass and the indicator will reach 100%.
