57 Wh lithium-ion replacement battery

This 57 Wh HP spare battery delivers 11.6 V and 4930 mAh for select HP laptops. It is a new three-cell lithium-ion unit built to original specifications. The pack suits owners who need a direct replacement for a depleted or failing original battery. Part number 863280855 identifies the exact fitment.

Upgrades from worn-out factory cells

The battery replaces an aged original that no longer holds a useful charge. Swapping it restores full mobile runtime without changing the laptop. The jump is worth it when the existing pack gives only a fraction of its rated capacity or triggers replacement warnings. Buyers needing higher capacity than 57 Wh or a different voltage should verify compatibility before ordering.
