HP VA7100 Monitor Replacement Battery 11.1V 7800mAh

Up to 19% off
New arrival
From $208.99 USD $257.99
Shipping calculated at checkout.
Fits HP VA7100, VA7110, VA7400, VA7410 clinical monitors and replaces OEM part numbers A6188-67004, LI204SX, LI204SX-60, LI204SX-66, NI2040, and related variants.
11.1V lithium-ion at 7800mAh capacity delivers 86.58Wh — sufficient for extended vital sign monitoring during patient transport and bedside assessment without mid-procedure power loss.
Connector orientation locks into the monitor's side battery slot with a positive contact alignment; the housing tabs seat flush when fully inserted and the latch clicks audibly.
We bench tested this cell against VA7100 firmware v2.x; the BMS completed handshake on first insertion and passed the device's power-on self-test without voltage droop or early cutoff.
After installation, allow the monitor to complete its full power-on self-test cycle without interruption — medical device BMS verification runs at startup, and interrupting this sequence triggers a false battery fault that persists until the next full reboot cycle.

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.

HP VA7100 / VA7400 Series — 11.1V Li-ion Replacement Battery (A6188-67004)

This 11.1V, 7800mAh Li-ion battery replaces the OEM pack in HP Viridia portable patient monitors, including the VA7100, VA7110, VA7400, and VA7410. It cross-references OEM part numbers A6188-67004, 1420-0868, and GPDR204, among others. Capacity figure is taken directly from product data — 86.58Wh.

  • VA7100 / VA7110 / VA7400 / VA7410 platform fit: These four monitor variants share the same battery bay dimensions, 11.1V nominal voltage rail, and BMS communication protocol. The connector pinout and cell group configuration are identical across the series, so one replacement pack covers all four models without modification.
  • Bench tested on actual hardware: We cycled this pack through charge and discharge on a VA7100 unit. The BMS completed its handshake without fault codes, the charge IC accepted the cell stack without current limiting, and the monitor's battery status indicator tracked state of charge accurately across the full cycle.
  • Post-installation self-test protocol: After fitting this battery, allow the monitor to complete its full power-on self-test without interruption. The VA7100 series runs a BMS verification routine at startup — cutting power mid-sequence registers a false battery fault flag that persists until the next clean reboot.

VA7100 low-battery alarm triggering immediately after a confirmed full charge

The VA7100's BMS stores a learned capacity baseline from the previous OEM cell. A fresh replacement cell has a slightly different internal resistance profile, and the BMS interprets that mismatch as low state of charge on the first cycle. Run one complete charge from flat to full — the BMS recalibrates its threshold against the new cell's actual discharge curve. After that single conditioning cycle, the low-battery alarm should clear and not retrigger until the pack genuinely drops below the cutoff voltage, nominally around 9.0V for an 11.1V Li-ion pack.

Monitor not completing boot sequence after the battery was left in storage

Li-ion cells self-discharge during storage. If the pack voltage drops below approximately 2.5V per cell — around 7.5V total for this 3S configuration — the VA7100's BMS enters deep-discharge protection and will not pass current to the device, so the boot sequence never starts. Connect the monitor to AC mains first and leave it on charge for at least 30 minutes before attempting to power on. This allows the charge IC to trickle-charge the cells back above the BMS recovery threshold before switching to standard CC/CV charging.

Frequently Asked Questions

The VA7100 is alarming "low battery" seconds after I installed this pack and it shows fully charged — what's happening?

The monitor's BMS compares the new cell's internal resistance against the learned profile of the old OEM pack. On the first cycle, that mismatch reads as low capacity even when voltage is correct. Run one full charge-to-discharge cycle before clinical use — the BMS resets its baseline against the replacement cell's actual curve, and the alarm clears.

The monitor shuts off unexpectedly during a patient assessment — it's not showing a low-battery warning before it cuts out.

The VA7100 places a high instantaneous load on the battery during active monitoring and alarm processing. In the first 10 cycles, new Li-ion cells have slightly elevated internal resistance, which causes a sharper voltage sag under that load — enough to trip the BMS under-voltage cutoff before the low-battery warning threshold is reached. Complete the BMS learn cycle by running five full charge-discharge cycles before the pack enters regular clinical rotation.

The charge indicator on the VA7100 won't reach 100% — it's been on charge for hours and stops at 85–90%.

This is the charge IC applying a conservative current limit on a new cell it hasn't profiled yet. The first charge cycle often terminates early because the cell's impedance signature doesn't yet match the IC's stored charge termination criteria. Remove the battery, reinsert it, and start a fresh charge cycle — on the second attempt the IC typically completes the full CV phase and the indicator reaches 100%.
