This NShi PG03XL is a lithium-ion laptop battery rated at 11.55V and 52.5Wh with a 3-cell layout. It is built as a direct replacement for HP Pavilion Gaming 15-DK and 15-EC series notebooks as well as OMEN 5X FPC52 models.

Compatibility check

PG03XL exists in two different physical designs that are not interchangeable. Verify that the original battery matches the product image and confirm the part number against PG03XL, HSTNN-OB1I, HSTNN-DB9G, L48495-005, L48430-AC1, L48430-AC2 or PGO3XL before ordering.

Sustained behaviour

For first use, discharge the pack to 5 percent then charge to 95 percent and repeat the cycle three to four times. This conditioning routine stabilises the cells for consistent output during extended sessions rather than only short bursts.

Questions about this item

Does the NShi PG03XL battery arrive with any tools or cables, or do I need to buy them separately?

The battery ships as a standalone unit; no screwdrivers, opening tools or extra cables are included, so you only need the Phillips screwdriver that fits your laptop chassis.

My original battery is marked PG03XL but the supplier notes two different designs — how do I pick the right one?

Compare the shape and connector position of your old battery with the product photo; the two PG03XL designs are not interchangeable, so visual match is the only reliable check.

What does the 52.5 Wh rating mean for actual runtime in an HP Pavilion Gaming 15-dk0131TX?

At 11.55 V and 4323 mAh the pack stores 52.5 Wh; real-world run time depends on your workload, screen brightness and power profile, but it restores the factory capacity for that model.
