Questions about this item

How long does the 50Wh capacity last under continuous load before the battery hits its voltage floor?

The 50Wh lithium-ion pack at 11.55V delivers its rated energy until the cells reach the built-in low-voltage cutoff; actual runtime varies with the ZenBook 13 workload and power-profile settings.

Does the C31N1724 generate noticeable heat or fan noise during all-day operation?

The battery itself is passive and produces no fan noise; warmth depends on the laptop's charging circuit and system load rather than the replacement cell.

Which Asus ZenBook 13 models must I already own for this 0B200-02760400 pack to fit?

It fits the UX331FA, UX331FAL, UX331UAL, UX331UN and U3100FAL series including sub-models such as UX331FA-A3071T, UX331FAL-EG002T and UX331UAL-EG053T.
