Sustained discharge with smart chip

The integrated smart control chip manages power flow to provide lower consumption and longer discharge time during extended sessions. Built-in protections guard against short circuit, overheat and overload conditions. Users who require hot-swap capability or external charging cradles will not find those functions here.

Limited to listed ProBook models

Compatibility is restricted to the specific ProBook series and original part numbers shown in the specifications. The pack follows the OEM electrical specification of 10.8V and 48Wh energy rating. Owners of newer HP laptops or non-ProBook chassis must verify fitment before purchase.

Questions about this item

How much heat does the 6-cell 10.8 V pack generate during a full day of use?

The lithium-ion cells run at 10.8 V and 4400 mAh, producing only modest warmth under normal load; no active cooling is required.

Does the battery slot straight into my ProBook 4530s without extra cables or brackets?

It replaces the original HP part numbers such as 633733-151 and HSTNN-XB2G, so it fits the existing bay with no additional hardware.

Will the smart control chip work with the charging circuit in my older ProBook 4430s?

The built-in chip manages charging, short-circuit, overheat and overload protection on the same 10.8 V rail used by the 4430s and other listed models.
