This replacement battery fits HP 420, 425, 620, 625 and ProBook 4320, 4320s, 4321, 4321s, 4320t models. It uses lithium-ion cells rated at 11.1V and 5200mAh capacity across six cells. The unit is supplied new and carries CE and RoHS certification. It is intended to restore original runtime to compatible notebooks.

Suits owners of listed HP models

Buyers whose laptop model is not in the compatibility list should look elsewhere, as fit and electrical matching cannot be assured. Users needing a higher capacity than 5200mAh or a different voltage will not be served by this part. The battery is designed only for the specific HP series named in the specifications.

5200mAh capacity decides runtime

The 5200mAh rating is the single figure that determines how long the laptop runs between charges. A lower capacity cell would give less operating time, while a higher capacity alternative would require a different physical pack. Confirm the 5200mAh value matches the original battery label before purchasing.

Questions about this item

When will the 6-cell 5200mAh pack need replacing?

Lithium-ion cells of this capacity typically deliver several hundred charge cycles before runtime drops noticeably; the supplier backs the pack with a one-year replacement warranty.

What limits runtime first during a full-day workload on the 11.1V 5200mAh battery?

The fixed 5200mAh capacity sets the energy ceiling; sustained high processor load or bright screen settings will drain the pack faster than light use.

How much heat or fan noise does the 6-cell lithium-ion add when the laptop runs all day?

The battery itself generates minimal heat and no noise; any warmth or fan activity comes from the laptop's own thermal system under load.
