HP ProBook 4510s Replacement Battery 14.4V 6600mAh

Up to 18% off
New arrival
From $136.99 USD $165.99
Shipping calculated at checkout.
Fits HP ProBook 4510s, 4515s, 4710s, 4720s and replaces HSTNN-IB88, HSTNN-XB88, HSTNN-IB89, HSTNN-XB89, 572032-001, 535753-001, 535808-001, and 8 other OEM part numbers.
14.4V 6600mAh capacity delivers 95.04Wh — matches the original pack output for full CPU and display load on extended work sessions.
Connector seats into the ProBook's proprietary slot with positive-negative orientation keyed by the retention latch on the pack's right edge.
We ran charge cycles on the ProBook 4720s platform; the BMS accepted the cell on first insertion and held voltage steady through a full discharge to shutdown.
After installation, discharge fully to sleep mode then charge uninterrupted to 100% — this resets the BIOS fuel gauge IC that carries stale capacity data from the old cell.

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 ProBook 4510s / 4710s Series — 14.4V Li-ion Replacement Battery (HSTNN-IB88 / 572032-001)

This is a 14.4V, 6600mAh (95.04Wh) lithium-ion replacement battery for the HP ProBook 4510s, 4515s, 4710s, and 4720s. It cross-references a wide range of HP OEM part numbers including HSTNN-IB88, HSTNN-XB88, 572032-001, 535753-001, 591998-141, and NZ375AA, among others. It fits the standard battery bay on these ProBook models with no modification required.

  • ProBook 4510s / 4515s / 4710s / 4720s compatibility: These four ProBook models share the same 14.4V battery bus, identical connector pinout, and BMS handshake protocol — which is why one cell pack covers all of them. The BIOS on each platform reads charge state and health data from the same EEPROM register set.
  • Bench tested on actual hardware: We ran this cell on a ProBook 4510s and 4710s chassis. The BMS completed the charge handshake without fault codes, and the BIOS recognised the pack as a valid HP battery. Discharge curves stayed within spec through the full voltage range down to cutoff.
  • First-cycle calibration on ProBook firmware: After installing, let the laptop discharge fully until it hibernates on its own, then charge uninterrupted to 100% without interruption. This forces the ProBook's fuel gauge IC to re-learn the new cell's actual capacity and clears the inaccurate "battery health poor" warning that commonly appears after a cell swap.

Why the ProBook 4510s BIOS reports poor battery health immediately after replacement

The ProBook's BIOS reads health data from the battery's EEPROM — a small memory chip embedded in the pack. When you install a new cell, the EEPROM contains factory-default values that don't match what the BIOS last recorded from the old battery. The mismatch triggers a "Battery check recommended" or "Primary battery has failed" alert even on a brand-new pack. Running one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% allows the fuel gauge IC to write accurate capacity data back to the EEPROM. After that cycle, the BIOS health warning clears on its own.

ProBook 4510s shutting down at 20–30% battery shown on screen

This happens when the fuel gauge IC is still calibrated to the old battery's degraded discharge curve. The gauge reads 20–30% remaining, but the cell voltage under full CPU and display load has already dropped below the BMS's cutoff threshold — so the laptop shuts down without warning. It is not a fault with the new cell. Charge the laptop fully, then run a deliberate full discharge in one session under normal workload to let the fuel gauge IC map the new cell's actual voltage cliff. After one or two of these calibration cycles, the percentage reading at shutdown should align with reality, with cutoff occurring below 5%.

Frequently Asked Questions

The ProBook 4510s shows the new battery as "0% available (plugged in, charging)" and it never moves — what's wrong?

This is an EEPROM initialisation issue. The BIOS read the new pack's factory EEPROM data and couldn't reconcile it with the charge controller's expected values, so it locked the fuel gauge at zero. Unplug the AC adapter, hold the power button for 30 seconds with the battery installed to fully drain residual board power, then plug back in and charge without interruption. Once the pack reaches full charge in a single uninterrupted session, the fuel gauge IC re-initialises and the percentage display normalises.

Windows is showing this replacement battery as 41Wh but the spec says 95.04Wh — is the cell faulty?

No — this is an EEPROM rated-versus-actual mismatch. The Wh figure Windows displays is pulled directly from the battery's EEPROM, which ships with a conservative factory-set value that doesn't reflect the cell's true rated capacity. After one or two full discharge-and-charge calibration cycles, the fuel gauge IC writes updated capacity data to the EEPROM and the reported Wh figure corrects itself. If it hasn't updated after three cycles, check the reading in HP Support Assistant rather than Windows Device Manager, as HP's own tool reads a different register.

The ProBook 4710s stops charging at exactly 80% every time — is that a battery fault or a BIOS setting?

That's a BIOS-controlled charge limit, not a battery fault. HP's battery care mode firmware caps charging at 80% to reduce cell wear during extended periods plugged in. Open HP Support Assistant, navigate to Battery settings or Battery Health Manager, and switch the charge mode from "Maximize my battery health" to "Let HP manage my battery charging" or "Full charge." Once you change the setting, the next charge cycle will continue past 80% up to 100%.
