Lithium-ion chemistry and capacity

The pack uses lithium-ion cells rated at 10.8 V and 4.4 Ah for 47.52 Wh of energy. In normal use it delivers the voltage and runtime expected from the original equipment battery without additional cooling requirements. Power draw follows the laptop's own management so thermals and noise remain unchanged from the factory configuration.

Black finish and form factor

The black casing measures 310.00 x 95.00 x 48.00 mm and is built to the same mechanical outline as the OEM unit. Connectors align with the existing battery bay so the latch engages securely and the pack sits flush with the chassis. No adapters or cable routing are needed for day-to-day operation.

Questions about this item

How do I install the DS-CS-HPF420NB battery in my HP ProBook 4320s, and which step is often missed?

Power off the laptop, disconnect the AC adapter, slide the release latch to unlock the old pack, remove it, insert the new battery until the latch clicks, then reconnect power and let it charge fully before first use.

What maintenance will the 10.8 V 4.4 Ah Li-ion pack need over its life?

No scheduled maintenance is required; keep the contacts clean, avoid storing the pack fully discharged, and recharge it every few months if the laptop is unused for long periods.

What limit appears first during sustained heavy use of this 47.52 Wh battery?

The 4.4 Ah capacity determines run-time; under continuous high load the pack will deplete faster and its voltage will drop to the cutoff point, ending the session until recharged.
