HP ProBook 5330m replacement battery

This lithium-polymer battery is built for HP ProBook 5330m laptops and their listed sub-models. It replaces the original 634818-271, 635146-001, FN04, HSTNN-DB0H and QK648AA packs. The 2.7 Ah capacity matches the factory specification. Buyers needing a battery for any other HP series cannot use this part.

2.7 Ah capacity and Li-Polymer chemistry

The cell chemistry and amp-hour rating define the practical runtime ceiling for this pack. A 2.7 Ah lithium-polymer unit delivers the same energy envelope as the original equipment battery. It will not extend run time beyond the laptop's design limits, and it cannot be fast-charged beyond the system controller's programmed rate.

Verify exact ProBook 5330m sub-model before ordering

The compatibility list covers many ProBook 5330m variants identified by their alphanumeric suffixes. Confirm that your unit's model number appears in the supported list; visually similar ProBook lines use different battery shapes and connectors. Installing this pack in an unlisted model risks physical mismatch or charging failure.

Yes, the 2.7 Ah Li-Polymer DS-CS-HPB533NB is built to match the original HP 634818-271 and 635146-001 specifications for every ProBook 5330m variant listed.

What runtime can I expect from the 2.7 Ah rating once the battery is installed in a ProBook 5330m?

The 2.7 Ah capacity restores the original design runtime for the ProBook 5330m; actual hours depend on screen brightness, workload and power-profile settings.

Yes, it fits the ProBook 5330m battery bay and communicates with the laptop’s charging circuit exactly like the FN04 HSTNN-DB0H original.
