Direct replacement for HP ProBook series
This new 6-cell lithium-ion battery matches the 10.8 V and 4400 mAh ratings of the original packs used in HP ProBook 6440b, 6445b, 6450b, 6455b, 6540b, 6545b, 6550b and 6555b models. It also fits Compaq 6530b, 6535b, 6730b and 6735b as well as HP EliteBook 6930p, 8440p and 8440w Mobile units. The black housing aligns with the OEM form factor so no chassis modification is required.
Built-in protection chip and one-year warranty
A smart control chip manages charging current, reduces idle draw and extends discharge time while providing short-circuit, overheat and overload safeguards. The supplier backs the pack with a one-year warranty from 2020 production onwards, reflecting the quality-control standard established in 2006. No additional cables, drivers or software utilities are bundled with the unit.
Suits owners of listed legacy HP
Buyers who need a drop-in power source for the exact models above will find the voltage, capacity and cell count match the factory specification. Users with newer HP laptops, different voltage requirements or higher-capacity demands should look elsewhere because this pack is limited to 48 Wh and the specific part numbers referenced.

Questions about this item
Does the 6-cell lithium-ion pack need any periodic calibration or user maintenance during its service life?
The built-in smart control chip manages charging and discharge automatically; no user calibration or scheduled maintenance is required for the 10.8 V 4400 mAh pack.
What limits runtime first when the laptop draws heavy load continuously?
The 48 Wh capacity sets the energy ceiling, so sustained high current draw will deplete the 6-cell pack before any thermal or voltage limit is reached.
How much heat or fan noise does the battery generate when the system runs all day?
The battery itself produces no audible noise and only modest warmth; any noticeable heat or fan activity comes from the laptop chassis, not the 10.8 V pack.
