Replacement battery for HP Pavilion 15-EG and 15-EH

The PISKEKAT HW03XL is a new lithium-ion battery rated at 11.34V and 41.04Wh. It replaces part numbers including HSTNN-IB90, HSTNN-LB8U and L96887-421. The unit fits HP Pavilion 15-EG, 15-EH and 15-EH0090WM series laptops as well as HP Laptop 17-CN, 17-CP, 240 G9, 245 G9, 250 G9, 255 G8, 255 G9 and 470 G8 models.

Thermals noise and power in normal use

The battery uses Grade A cells with a built-in safeguard chip that authenticates with the system. Lithium-ion chemistry provides stable voltage delivery during typical workloads. No active cooling is required and the pack operates silently. Certifications cover UL, CE, FCC and RoHS compliance for safety.

What the bundled safeguards change

The authentication chip ensures the laptop recognises the pack and enables full charging routines. Safety certifications mean the unit meets baseline electrical and environmental standards. Buyers needing higher capacity than 41.04Wh or a different voltage should look elsewhere. The package contains only the battery itself.

Questions about this item

How do I install the HW03XL 11.34V 41.04Wh battery in my HP Pavilion 15-EG and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery cable from the motherboard, fit the new HW03XL pack, reconnect the cable, replace the base and screws, then charge fully before first use.

What maintenance or replacement will the HW03XL 41.04Wh Li-ion battery need later?

The sealed pack is maintenance-free; after several hundred charge cycles the runtime will fall noticeably, at which point the whole HW03XL battery must be replaced.

What limit appears first on the HW03XL 11.34V battery during sustained heavy use?

Under continuous high load the cell voltage drops to the protection threshold and the safeguard chip shuts the pack down to prevent deep discharge.
