Replacement battery for HP Notebook

The PISKEKAT HS04 HS03 is a new 4-cell lithium-ion laptop battery rated at 2200mAh and 33Wh. It operates at 14.8V and is compatible with 14.4V systems. The unit includes over-charge, over-discharge, over-voltage and short-circuit protection and carries CE, FCC and RoHS compliance. It is designed for owners of compatible HP Notebook 14, 14g, 15, 15g and Pavilion 14-ac, 14g-ad, 15-ac, 15g-ad models who need a direct replacement.

Upgrading from a depleted or failing original pack

This battery replaces a long list of HP spare part numbers including 807956-001, 807957-001, 807612-421, 807611-221, HSTNN-LB6U, HSTNN-DB7I, HSTNN-LB6V, TPN-I119 and many others. The jump is worth it when the original pack no longer holds sufficient charge or has been flagged by the system as degraded. It is not for buyers who need a higher-capacity 6-cell or 9-cell alternative, nor for laptops outside the listed HP part-number range.

Fits into the existing battery bay without

The black pack slots into the same compartment as the original HP battery and uses the same latch mechanism. No additional cabling, adapters or firmware updates are required. It frees the user from permanent tethering to an AC adapter and restores portable runtime for supported models such as the 15-BA009DX, 15-AY039WM, 14-AM052NR and 17-X051NR. Ensure the part number on the old battery matches the compatibility list before fitting.

Questions about this item

Will the 4-cell 2200mAh pack fit the HP Pavilion 15-ac0XX battery bay?

The battery matches the HS03/HS04 form factor used in HP Pavilion 15-ac0XX and 15g-ad0XX models, so it seats directly in the existing bay.

What is the correct order to connect the 14.8 V pack when installing it?

Power off the laptop, unplug the AC adapter, remove the old pack, insert the new one until the latch clicks, then reconnect AC power before turning on.

How long will the 33 Wh lithium-ion pack hold a useful charge before it needs replacing?

The 4-cell 33 Wh lithium-ion unit delivers normal runtime for its rated cycle life; capacity gradually declines with age and heavy use.
