Replacement battery for Zephyrus S GX531

This new lithium-polymer battery replaces the original C41N1805 unit in Asus ROG Zephyrus S GX531 series laptops. It delivers 15.4 V and 50 Wh capacity for owners whose factory pack no longer holds a charge. The black cell fits the slim chassis without modification.

Direct-fit design restores original runtime

The pack matches part numbers C41N1805, 0B200-03020000 and 4ICP4/72/75, so it seats in the existing bay and connects to the stock connector. No extra cables, adapters or firmware updates are required; the laptop recognises the battery immediately. A twelve-month warranty covers the replacement.

15.4 V 50 Wh capacity decides compatibility

Only machines that specify a 15.4 V 50 Wh lithium-polymer pack should use this unit; higher- or lower-voltage models will not operate correctly. Buyers needing a different voltage, a larger capacity or a battery for another laptop series must select a different part.

Questions about this item

When will the C41N1805 50Wh lithium-ion battery need replacing?

The 15.4V 3160mAh pack is rated for hundreds of charge cycles; typical daily use sees capacity drop to 80 % after 12 to 18 months, at which point a fresh C41N1805 restores original runtime.

What limits runtime first during a long gaming session on the GX531?

The 50Wh capacity is the hard ceiling; once the 3160mAh cells deplete, the laptop must shut down or switch to AC power regardless of thermal headroom.

Does the 4ICP4/72/75 battery get hot or noisy when the Zephyrus S runs all day?

The battery itself has no fan and generates only modest warmth during discharge; any heat or noise comes from the laptop's own cooling system, not the pack.
