37Wh replacement battery for Asus F455

This 7.6V lithium-polymer pack delivers 37Wh and 4775mAh to restore runtime on compatible Asus laptops. It replaces the original C21N1401 cell and fits models such as F455L, F455LD, X455L, X455LA and R455L. The black finish matches the factory look.

Direct-fit design limited to listed Asus part

The battery only works with the exact models named in the compatibility list including F454L, Y483L and VM410L. It cannot be used in other Asus series or in laptops from different manufacturers. Physical dimensions and connector layout match the OEM part exactly.

Upgrades worn or failed C21N1401 cells

Swapping the old pack restores full charge capacity when the original no longer holds a usable charge. The jump is worth it when runtime has dropped below daily needs and the laptop model appears in the fit list. Machines outside that list require a different part number.

Questions about this item

Should I choose the 37 Wh version or the 4775 mAh rating for my Asus F455L?

Both figures describe the same battery — 37 Wh at 7.6 V equals 4775 mAh, so there is no separate version to pick.

What runtime can I expect from the 37 Wh battery in an Asus X455LA?

The 37 Wh pack delivers roughly the same run-time as the original C21N1401; actual hours depend on screen brightness, workload and power settings.

Does the 7.6 V output match the charging circuit in the R455LD?

Yes, the 7.6 V rating is identical to the factory C21N1401 specification, so the laptop's charging controller will recognise it normally.
