Replacement for HP Pavilion 15-AU series

This new lithium-polymer battery replaces the original HP BP02XL and BP02041XL packs. It fits a long list of 15-AU models including 15-AU000, 15-AU103NG, 15-AU105NG and many others through 15-AU147TX. The 7.4 V, 4900 mAh cell restores factory runtime for daily office work and study sessions. A built-in smart chip manages charging and protects against short circuit, overheat and overload.

Upgrade from a worn or swollen pack

Swap this in when the original battery no longer holds a charge, shows swelling or triggers a BIOS capacity warning. The jump is worth it if your laptop now tethers to a wall outlet or shuts down under moderate load. It matches the OEM 7.7 V device voltage and 38 Wh energy rating, so the power curve stays identical to the factory part. Buyers who need a higher-capacity pack for all-day unplugged use will not find that option here.

4900 mAh capacity for typical workloads

The 38 Wh pack comfortably handles web browsing, document editing and video playback for several hours on a full charge. Heavy loads such as sustained gaming, rendering or virtual machines will drain it faster and may hit the protection limits sooner. The smart control chip optimises discharge time and lowers idle consumption, but it cannot extend the physical cell capacity beyond the rated figure. Users who need multiple full workdays between charges should look elsewhere.

Questions about this item

Does the MPL08318P-25 battery match the screw-hole layout and connector of the HP Pavilion 15-AU103NG?

This replacement is built for the HP Pavilion 15-AU series including the 15-AU103NG, so the mounting points and connector align with the original BP02XL pack.

What is the most common mistake when fitting this 7.4 V lithium-polymer pack into a 15-AU105NG?

Forgetting to disconnect the internal battery cable before removing the old pack can trigger a short-circuit protection lockout on the new 4900 mAh unit.

When should I expect to replace the MPL08318P-25 in my 15-AU107NG?

Replace it once the runtime falls well below the rated 38 Wh or the battery no longer holds a full 7.4 V charge.
