Questions about this item

How long does the 53.2 Wh capacity last before the battery needs recharging under sustained load?

The 53.2 Wh rating indicates the energy the pack stores; actual runtime varies with the laptop's power draw, screen brightness and workload.

Does the pack run hot or make noise when the laptop is used all day?

Lithium-ion cells generate some heat during discharge but have no moving parts, so the battery itself is silent and stays within normal operating temperatures.

Which HP laptop models does the L08544-1C1 part number fit?

This battery is listed as compatible with HP part numbers L08544-1C1, L08544-2B1, TPN-W133, TPN-W136 and KCO4XL.
