Replacement Battery for HP Pavilion

This 10.8V lithium-ion unit supplies 47Wh across four cells and carries UL certification. It is built for owners of the listed HP and Compaq notebooks who need a direct swap for an aging or failed original pack. The black housing matches the OEM colour scheme.

Verify Part Number and Voltage Before Purchase

Confirm that your current battery shows one of the compatible part numbers such as 593553-001, MU06 or MU09 and that the label reads 10.8V. The pack fits the specific models listed in the compatibility table and will not work in laptops requiring a different voltage or connector layout.

Four-Cell Polymer Construction with UL Safety Mark

The lithium-polymer cells are enclosed in a rigid black shell that resists flex during daily insertion and removal. UL certification means the pack has passed recognised electrical and thermal tests, reducing the risk of overheating. The connector aligns with the original bay for a secure, repeatable fit.
