Build quality and daily fit

The pack uses six grade A cells rated at 11.1V and is also compatible with 10.8V systems. CE FCC and RoHS certifications confirm regulatory compliance. Built-in circuit protection guards against overcharge over-discharge and short circuits. The slim profile slides into the existing battery bay without adapters or case modifications.

Thermals noise and power draw

Lithium-ion chemistry runs cool during typical office workloads and produces no audible noise. Low self-discharge keeps the charge stable when the notebook is stored. The 5200mAh capacity delivers extended runtime compared with lower-rated packs while the protection circuit maintains safe voltage limits throughout the discharge cycle.

Questions about this item

What voltage does the 11.1V 5200mAh lithium-ion battery deliver, and how does it relate to the 10.8V rating?

The pack is rated at 11.1V and is fully compatible with systems that specify 10.8V; both voltages refer to the same six-cell lithium-ion chemistry and will operate interchangeably in the listed ProBook models.

Which ProBook chassis does the six-cell 5200mAh pack fit without modification?

It fits HP ProBook 4330s, 4331s, 4430s, 4431s, 4530s, 4535s, 4435s, 4436s, 4440s, 4441s, 4446s, 4540s, 4545s and 7420 models that originally used a six-cell HSTNN-xxxx or PR06/PR09 battery.

How is the battery installed, and what step do people often miss?

Power off the laptop, disconnect the AC adapter, slide the release latch to eject the old pack, insert the new battery until the latch clicks, then charge it fully before first use — skipping the full initial charge is the most common oversight.
