POWER-FENG C41N1814 73Wh Battery

The POWER-FENG C41N1814 is a 73Wh lithium-polymer replacement battery rated at 15.4V and 4680mAh. It is built for Asus ZenBook 15 models including UX533FD, UX533FN, RX533FD and U5300 series laptops. The black pack matches the original form factor and installs internally without modification.

Replaces C41N1814 part numbers

This unit replaces the original C41N1814 battery shipped with the listed ZenBook 15 chassis. The upgrade is worthwhile when the factory cell no longer holds a full charge, shows rapid drain or triggers a low-capacity warning in the operating system. A fresh 73Wh pack restores the runtime the notebook delivered when new.

Check model and connector before ordering

Verify the exact model number on the bottom case or in BIOS against the supported list: UX533, UX533FD, UX533FN, RX533, RX533FD, U5300F, U5300FN, U5300FD, BX533FD and U5300F. Confirm the voltage label reads 15.4V and that the connector layout matches the original battery. This battery is not for users needing a higher-capacity design or a different voltage.

Questions about this item

Does the 73Wh 15.4V battery fit the UX533FD chassis without modification?

The pack is built to the C41N1814 form factor and lists UX533FD among its compatible models, so it matches the original mounting points and connector.

What is the correct sequence when installing the C41N1814 replacement?

Power off the notebook, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector before lifting the pack, then connect the new battery before reassembling.

When should the 4680mAh Li-polymer pack be replaced?

Replace the unit when runtime becomes noticeably shorter or the system reports a significant capacity loss, as Li-polymer cells degrade gradually with charge cycles.
