Replacement battery for HP notebooks

This 14.8V 2200mAh 4-cell pack replaces HS04 and HS03 units in compatible HP 14, 15, Pavilion and G4/G5 series laptops. It uses Grade A cells and built-in circuit protection for stable operation. The unit is new from the manufacturer and rated for up to 500 recharge cycles.

Thermal and power behaviour

The battery delivers its rated capacity at 14.8V with low self-discharge during normal use. Circuit protection guards against over-charge, over-discharge and short-circuit conditions. No active cooling is required and the pack adds no audible noise to the system.

When the swap makes sense

Owners of the listed HP models whose original pack no longer holds a useful charge will regain full mobile runtime with this direct replacement. It is not suited for laptops that require a different voltage, cell count or connector keying.

Questions about this item

How do I install the HS04 battery and what step is often missed?

Power off the laptop, remove the AC adapter, slide the release latch, insert the 4-cell 14.8V pack until it clicks, then reattach the adapter and let it charge to 100% before first use.

When will the 2200mAh Grade A cells need replacement?

The cells are rated for up to 500 recharge cycles; after that capacity drops noticeably and a new battery is recommended.

What runtime limit appears first during a long work session?

The 2200mAh capacity determines how long the notebook runs on battery; sustained load will hit that limit before the built-in circuit protection activates.
