For HP owners matching the part number

Buyers who confirm their original battery shows SS03XL or one of the listed compatibles will have a direct fit. Those with different EliteBook generations, other HP series or non-HP laptops cannot use this pack. Users needing a higher or lower capacity must choose another model.

Voltage and capacity define the fit

The 11.55V 50Wh rating (4330mAh) is the single figure that decides compatibility. If the original battery label reads a different voltage or watt-hour value, this unit will not work. Always verify the part number on the old battery before ordering.

Questions about this item

How long does the SS03XL 11.55V 50Wh battery last before it needs replacing?

The lithium-ion pack is rated at 50Wh and 4330mAh; capacity will gradually decline with charge cycles, so plan to replace it when run time no longer meets your needs.

What limits the SS03XL during sustained use?

The 50Wh capacity sets the runtime ceiling; under continuous load the battery will deplete at a rate determined by the laptop's power draw.

Does the SS03XL get hot or draw extra power when running all day?

Normal operation stays within the 11.55V design voltage; heat and power draw depend on the host laptop's workload and cooling, not the battery itself.
