Fits HP Pavilion 13-AN0006TU 5GR09PA and replaces MM02XL, HSTNN-DB8U, HSTNN-IB8Q original battery.
7.6V and 4750mAh capacity restores full charge cycles on this ultrabook without voltage sag under load.
Connector slides straight into the original battery slot with no mechanical modification or adapter needed.
We ran a full discharge-to-hibernate cycle then recharged to 100% with no thermal spike or BMS fault.
After installation, run one complete discharge to sleep then charge uninterrupted to 100% — this resets the BIOS fuel gauge IC and clears the inaccurate health warning that appears after every cell swap.

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 Pavilion 13-AN0006TU 5GR09PA — 7.6V Li-Polymer Replacement Battery (MM02XL)

This is a 7.6V, 4750mAh (36.1Wh) Li-Polymer replacement battery for the HP Pavilion 13 AN-series ultrabook. It fits the Pavilion 13-AN0006TU 5GR09PA and over 120 other AN-series variants including the AN0004TU, AN0035TU, and AN0014NF. OEM cross-references include MM02XL, HSTNN-DB8U, HSTNN-IB8Q, L27868-1C1, L27868-2D1, L28076-005, and MM02037XL.

  • AN-series compatibility: The entire Pavilion 13 AN-series shares a common 7.6V battery rail, a single ZIF connector pinout, and the same BMS handshake protocol — which is why one cell covers 125-plus models across the range.
  • Bench tested on actual hardware: We ran this cell in an AN-series unit and cycled it through full charge and discharge. The BMS negotiated correctly, the fuel gauge IC locked onto the new cell without fault codes, and charge acceptance held steady across three consecutive cycles.
  • Post-install calibration for the AN-series: After fitting, let the laptop discharge fully until it hibernates, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after swap on the Pavilion 13

The HP Pavilion 13's BIOS reads health status from EEPROM data embedded in the battery controller — data that was written for the old, degraded cell. When a new cell goes in, that stale EEPROM state still shows the previous battery's wear level. The BIOS interprets this as the replacement cell already being in poor condition. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to execute its battery learn cycle, overwriting the old EEPROM health data with fresh readings from the new cell.

Pavilion 13 shutting down at 20–30% charge shown on screen

This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The IC still maps the old cell's discharge profile, so it reads 20–30% remaining at a point where the new cell's voltage is already near its cutoff floor under combined CPU and display load. The laptop interprets that voltage drop as a critical shutdown event. Run two full discharge-to-hibernate and full-recharge cycles — after that, the gauge recalibrates and the remaining percentage reading stabilises. Target a resting voltage of around 8.4V at full charge to confirm the cell is healthy.

Frequently Asked Questions

Why does HP Support Assistant show my new battery as "0% available (plugged in, not charging)" right after installation?

The fuel gauge IC on the MM02XL cell needs at least one full discharge-to-hibernate cycle before the HP battery driver recognises it correctly. Until that cycle runs, the EEPROM data from the old cell is still active and the OS reports a null or zero state. Plug in, let it charge uninterrupted to 100%, then run it down fully to hibernate. After that cycle, the driver re-reads the cell and the charge percentage displays correctly.

My Pavilion 13 says it's charged to 100% but Windows shows the Wh rating as lower than the original battery — is the cell faulty?

It is not a fault. The Wh figure Windows displays is pulled from EEPROM data on the battery controller, which may reflect a rated value from a slightly different cell variant in the MM02XL family. The actual energy capacity of the installed cell is 36.1Wh. If the displayed Wh figure concerns you, check it against the label on the battery itself — the EEPROM value and the physical label may differ by a small margin, but real-world capacity is set by the cell chemistry, not the software register.

The Pavilion 13 stops charging at 80% and won't go higher — is this a problem with the replacement cell?

This is almost always a BIOS-controlled charge limit, not a battery fault. HP's Battery Care Manager or Adaptive Battery Optimiser can cap charging at 80% to reduce cell stress — the setting survives a battery swap because it lives in firmware, not in the cell itself. Open HP Support Assistant, go to Battery settings, and check whether an 80% charge limit is enabled. Disable it, unplug and replug the charger, and the battery will charge to 100%.
