6-Cell 10.8V Replacement Battery

This 6-cell lithium-ion battery delivers 5200mAh capacity at 10.8V for HP ProBook models including the 4530S, 4540S and 4430S series. It is built with Grade A cells and includes integrated circuit protection for stable charging and safe operation. The unit is supplied new from the manufacturer and rated for up to 500 recharge cycles over its service life.

Practical Runtime and Compatibility Limits

Typical operation time is around two hours, though actual duration varies with system power draw and usage patterns. The battery fits a wide range of ProBook models such as the 4330s, 4331s, 4431s, 4435s, 4535s, 4536s, 4440s, 4441s, 4446s and 4545s. It is not suited for laptops requiring a different voltage, cell count or connector layout.

Upgrade from Lower-Capacity Packs

This 5200mAh pack replaces the standard 4400mAh batteries originally shipped with many of these notebooks, offering a modest increase in stored energy. The jump is worthwhile when the original cell no longer holds a useful charge or when slightly longer unplugged sessions are needed. It does not address needs for extended all-day runtime or high-drain workloads.

Questions about this item

Should I choose the 5200 mAh or the 4400 mAh version for my ProBook 4530S?

The 5200 mAh version offers higher capacity than the 4400 mAh option, giving longer potential run time on the same 10.8 V platform.

What does the 5200 mAh rating mean for real-world use on a ProBook 4540S?

The manufacturer estimates around 2 hours of operation, though actual time varies with workload, screen brightness and power settings.

Does the 10.8 V lithium-ion battery work with the ProBook 4430S charging circuit?

Yes, the 10.8 V 6-cell pack matches the voltage and cell count specified for the 4430S series, and the built-in protection circuit manages charge safety.
