FOCUSTEC LA03DF 31Wh replacement battery

This new lithium-ion pack delivers 11.1 volts and 2600 milliampere-hours across three cells. It replaces the HP 776622-001 unit and fits a wide range of Pavilion 14-Y, 15-F and 15-N series laptops. The black housing matches the original colour and an instruction sheet is included in the box.

Steady discharge across a work session

The 31 watt-hour capacity supports typical office tasks, web browsing and video playback without a sharp voltage drop mid-session. Internal cell balancing maintains consistent output until the pack reaches its low-voltage threshold, so the laptop does not throttle unexpectedly during longer meetings or classes.

Direct swap with the original latch

Installation requires removing the bottom case screws, disconnecting the old pack and snapping this unit into the same connector and retention clips. No soldering or firmware update is needed. Builders who need a higher-capacity 4-cell or 6-cell design will not be served by this 3-cell form factor.

Questions about this item

Does the 11.1V 2600mAh LA03DF battery generate noticeable heat during all-day use?

The lithium-ion 3-cell pack runs at 11.1V and 31Wh; under normal loads it stays within typical laptop thermal limits.

What must my HP laptop already have to accept this LA03DF replacement?

Your machine must use one of the listed part numbers such as 776622-001, 728460-001 or HSTNN-DB5M and be a compatible 14-y, 15-f or 15-n series model.

Will this 31Wh LA03DF work alongside the original charger on my older HP Pavilion 15-n200?

Yes, it replaces batteries like HSTNN-UB5M and TPN-Q129 used in the 15-n200 series, so the existing AC adapter charges it normally.
