Replacement battery for HP and Compaq laptops

This 6-cell lithium-ion unit delivers 10.8 volts and 4400 mAh of capacity to restore runtime on compatible HP Pavilion, G-series, HDX and Compaq Presario models. It is a new replacement part built to OEM specification levels with a smart control chip that manages charging and discharge cycles. The battery suits owners of the listed notebooks who need a direct swap for an ageing original pack.

Built-in protections and charging management

The integrated circuit provides short-circuit, overheat and overload safeguards while enabling quicker charging and lower power consumption during use. No extra cables, software or mounting hardware are included in the package. Buyers who need a higher-capacity 9-cell option or an external charger will not find those functions here.

Black 6-cell housing with OEM-fit connectors

The pack uses a standard lithium-ion cell layout rated at 48 Wh and carries a one-year manufacturer warranty from a brand established in 2006. Its connector pattern matches the original part numbers such as 511883-001, 511884-001 and HSTNN-DB72 for tool-free installation. Users whose laptops fall outside the stated compatibility list should verify fitment before ordering.

Questions about this item

How many charge cycles can the 6-cell 4400mAh lithium-ion pack handle before it needs replacing?

The battery uses professional-grade cells built to OEM specification; typical lithium-ion packs of this type deliver several hundred full cycles before noticeable capacity loss.

Which limit appears first during long sessions — the 10.8V voltage floor or the 48Wh capacity ceiling?

The 48Wh capacity ceiling is reached first; the pack supplies 10.8V until the stored 4400mAh is depleted, then voltage drops as protection triggers.

Does the built-in smart control chip add audible fan noise or noticeable heat when the laptop runs all day?

The chip manages charging and protection silently; it produces no fan noise and only minimal warmth during extended use.
