58 Wh 10.8 V replacement battery

This 58 Wh 10.8 V lithium-ion battery replaces part numbers PH06, PH09 and 593572-001 in HP ProBook and Compaq laptops. It is built for models such as the ProBook 4320, 4420, 4520, 620 and 625 series. Buyers confirm the old battery label matches one of these identifiers before ordering.

Upgrade from depleted or lower-capacity packs

The unit restores original runtime when the factory cell no longer holds charge. It also serves as a spare for field work where a second battery extends the working day. Users whose part number is not PH06, PH09 or 593572-001 cannot use this pack.

Limits of the 10.8 V form factor

The brick fits only the listed ProBook and Compaq chassis that accept the PH06/PH09 mechanical profile. It will not work in newer ultrabooks, consumer Pavilion lines or any system requiring a different voltage or connector keying. Capacity is fixed at 58 Wh and cannot be expanded.

Questions about this item

Will the PH06 58 Wh battery fit my HP ProBook 4520s without modification?

Yes, the battery is a direct replacement for part numbers 593572-001, PH06 and PH09, matching the ProBook 4520s battery bay exactly.

What is the correct way to install the PH06 battery and what step do people often miss?

Power off the laptop, unplug the AC adapter, slide the old pack out, insert the new PH06 until the latch clicks, then charge it fully before first use — skipping the full initial charge is the common mistake.

When will the PH06 58 Wh battery need replacing?

The lithium-ion pack will gradually lose capacity; replace it when run time no longer meets your needs.
