Fits HP Business Notebook 8700 and replaces OEM part numbers 372771-001, 381374-001, 398876-001, HSTNN-DB06, HSTNN-DB11, HSTNN-LB11, and HSTNN-OB06.
14.8V lithium-ion at 4400mAh delivers 65.12Wh — matches original output for full CPU and display load cycles.
Connector slides into the battery bay slot with a single locking tab; orientation is keyed to prevent reverse insertion.
We bench tested the cell against a known-good 8700 charger; the BMS accepted the handshake on first insertion and reached full charge without voltage regulation faults.
After installation, run one full discharge to hibernation cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears inaccurate health warnings that appear after cell swaps.

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 Business Notebook 8700 Series — 14.8V Li-ion Replacement Battery (372771-001)

This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for the HP Business Notebook 8700 and its close variants, including the nw8440 and 8510w Mobile Workstation. It covers the full range of OEM part numbers under this platform — 372771-001, HSTNN-DB06, HSTNN-LB11, PB992A, and others. If your original battery no longer holds a charge or fails to power the system, this is the direct cell replacement.

  • 8700 and nw8440 platform compatibility: These models share a common 14.8V power rail, identical connector pinout, and the same BMS handshake protocol — which is why one cell works across 25-plus model variants. The battery pack identifies itself to the BIOS via the same EEPROM signature, so the system accepts it without driver conflicts.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an 8510w unit. The BMS engaged cutoff correctly at low voltage, and the BIOS recognised the pack without flagging unknown device status on first boot.
  • Post-install calibration on 8700 series: After fitting this battery, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that often appears after a cell swap on this platform.

BIOS reporting battery health as poor immediately after replacement

The HP BIOS on 8700-series machines stores battery health data in EEPROM and compares it against the new cell on first boot. A freshly installed cell has no discharge history, so the BIOS flags it as degraded — not because the cell is faulty, but because the learn cycle hasn't run yet. Complete one full discharge-to-hibernate followed by an uninterrupted charge to 100%. After that cycle, the health status normalises and the warning clears.

Laptop shuts down at 20–30% charge shown on screen

This happens when the fuel gauge IC is still calibrated to the old, degraded cell and misreads the new cell's actual state of charge. Under full CPU and display load, the 8700 draws enough current to expose the voltage cliff — the real cell voltage drops below the cutoff threshold even though the OS gauge still shows 20–30% remaining. The fix is a calibration cycle: discharge fully to automatic hibernate, then charge to 100% without interruption. After two or three cycles the fuel gauge IC re-maps to the new cell's actual voltage curve and the early shutdowns stop.

Frequently Asked Questions

HP Assistant says my new battery Wh rating is wrong — it shows a different number than what I paid for. Is the cell actually correct?

The Wh figure shown in HP Support Assistant pulls from the EEPROM data embedded in the battery pack, and that value is set at the factory based on the rated chemistry — not the measured cell at your specific charge state. The 65.12Wh spec on this cell is accurate. Run one full discharge-to-hibernate cycle followed by a complete uninterrupted charge and re-check the reading — the reported Wh figure typically corrects itself once the fuel gauge IC has a full baseline cycle to work from.

The fuel gauge is jumping around wildly — showing 80%, then 45%, then 90% within a few minutes. What's causing that?

The fuel gauge IC on the 8700 platform was calibrated against the old degraded cell, so it has no accurate voltage-to-capacity map for the new chemistry. It is not a fault with the replacement cell. Run two full discharge cycles to hibernate cutoff, charging to 100% uninterrupted between each. By the second or third cycle the IC has enough data to lock onto the new cell's actual voltage curve and the gauge stabilises.

Charge stops at 80% and the laptop won't go past that no matter how long it stays plugged in. Is the battery defective?

This is almost always a BIOS-controlled charge limit, not a fault in the cell itself. HP's battery care settings on 8700-series machines include an 80% charge cap to reduce wear — it can be enabled without the user knowing, sometimes carried over from a previous HP Support Assistant configuration. Open HP Support Assistant or check BIOS under Power Management and look for a battery charge limit or optimised charging setting. Disable it, then reconnect the charger — the battery will charge to 100%.
