ADC 9005BAT Replacement Battery 7.4V 7800mAh Li-ion

Up to 19% off
New arrival
From $91.99 USD $113.99
Shipping calculated at checkout.
Fits ADC ADView 2 Modular Diagnostic Station; replaces OEM part numbers 9005BAT, 120044-O, ND2057HD34, SUN17-0022-00.
7.4V, 7800mAh lithium-ion cell delivers 57.72Wh to sustain full diagnostic cycles without mid-session shutdowns.
Connector slides straight into the battery compartment with a positive locking tab that clicks once seated fully.
We bench-tested this cell in the ADView 2 platform; the BMS accepted the pack on first insertion with no fault codes.
Allow the device to complete its full power-on self-test cycle without interruption after installation — the diagnostic unit verifies new battery firmware compatibility at startup, and interrupting this sequence causes a false low-battery alarm that only clears after a complete restart.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

ADC ADView 2 Modular Diagnostic Station — 7.4V Li-ion Replacement Battery (9005BAT)

This 7.4V, 7800mAh Li-ion battery replaces the OEM 9005BAT cell in the ADC ADView 2 Modular Diagnostic Station and the ADView2 Diagnostic platform. It cross-references part numbers 120044-O, ND2057HD34, and SUN17-0022-00. Capacity is rated at 57.72Wh, matching the original power specification for this portable clinical workstation.

  • ADView 2 and ADView2 Diagnostic compatibility: Both platforms share the same 7.4V two-cell Li-ion architecture, identical connector pinout, and the same BMS handshake protocol — one battery cell covers both variants without modification.
  • Bench tested on actual hardware: We ran the cell through the ADView 2 power-on self-test sequence and confirmed the BMS reported correct voltage, passed the charge-state verification, and held load under the device's multi-sensor draw profile without triggering a fault condition.
  • Post-swap self-test protocol: After installing this battery, let the ADView 2 complete its full power-on self-test cycle without interruption. The BMS runs a chemistry verification at startup — cutting power during this sequence causes a false battery fault flag that persists until the next clean reboot.

ADView 2 not completing boot sequence on a new battery

The ADView 2 runs a BMS verification pass during every boot cycle. A new cell with no charge history can sit just below the device's minimum boot-voltage threshold, typically around 7.0V, even when it left the warehouse partially charged. If the unit stalls mid-boot or displays a power fault, connect the AC adapter before pressing the power button. This lets the device draw from mains while the BMS brings the new cell up to its operating band, clearing the boot stall without a firmware reset.

Charge indicator not reaching 100% on the first charge cycle

The ADView 2 charge IC applies a conservative current ceiling on cells it hasn't profiled yet — this is normal behaviour on cycle one and is not a cell defect. The indicator typically stalls between 90–95% and the device may report a reduced state of charge. Run one complete charge from flat to full without interrupting the session. After that first full cycle the charge IC updates its cell model and subsequent charges reach 100% accurately.

Frequently Asked Questions

The ADView 2 is alarming low battery straight after I charged the new cell overnight — did I get a dead battery?

The ADView 2 BMS is calibrated to the OEM cell's charge curve, and a new replacement cell needs one full discharge-to-charge cycle before the BMS accepts its state-of-charge readings as valid. Until that cycle completes, the device reads the cell as below threshold even at full charge and throws the low-battery alarm. Run the unit on battery until it shuts off from depletion, then charge uninterrupted to full — after that cycle the alarm clears and the BMS tracks the cell correctly.

The ADView 2 won't power on at all after the replacement battery sat in the box for a few months before installation — is the cell dead?

Li-ion cells self-discharge during storage, and if the cell dropped below the ADView 2 BMS recovery threshold — approximately 6.0V for a 7.4V two-cell pack — the BMS enters deep-discharge lockout and blocks power-on to protect the cell. Connect the AC adapter and leave the unit plugged in for at least 30 minutes before attempting to power on; the charger will trickle-charge the pack back above the recovery threshold. Once the cell reaches roughly 6.5V the BMS releases the lockout and normal boot resumes.

The ADView 2 is shutting off unexpectedly mid-assessment during the first week of use — is this a fault?

New Li-ion cells have slightly higher internal resistance in the first 10 charge cycles, which causes a larger voltage sag under the ADView 2's peak load — running the blood pressure module, SpO2, and display simultaneously. That sag can briefly push cell voltage below the BMS cutoff threshold, triggering an unexpected shutdown even when the charge indicator shows plenty of capacity remaining. The sag reduces as the cells condition through those first cycles. To get through the conditioning period, avoid running all sensor modules simultaneously and keep the AC adapter connected during heavy diagnostic sessions where possible.
