Compatible ASUS series

This 4-cell lithium-ion battery replaces the original A41-X550A pack in ASUS X550, X450, X452, Y481 and Y581 series laptops. It is a brand-new replacement unit built with Korean cells and rated at 2950 mAh or 44 Wh. The pack suits owners who need a direct swap for a depleted factory battery.

Sustained discharge behaviour

The 15 V nominal output and 14.4 V rated voltage deliver steady power throughout the discharge curve rather than a brief peak. Four cells share the load, reducing per-cell stress during long work sessions. The 44 Wh capacity supports typical office workloads for multiple hours before recharge is required.

Voltage and capacity limits

The pack operates within a 15 V / 14.4 V window and cannot supply higher voltages demanded by some gaming or workstation models. Its 2950 mAh capacity sets a hard ceiling on runtime, so users needing all-day mobility away from mains power will find the reserve insufficient.

Questions about this item

Does the 4-cell lithium-ion pack run hot or draw extra power during all-day use?

The 15 V 2950 mAh lithium-ion cells are made in Korea and rated at 44 Wh, matching the original specification so heat and power draw stay within normal limits for the X550 series.

What must my laptop already have for this A41-X550A to fit and work?

Your Asus notebook must use the A41-X550A part number — compatible models include X550C, X452E, X450L, F550, K550 and other 450, 550, 452 series laptops listed for this battery.

Will the 14.4 V / 15 V dual-voltage rating work safely in my older X450C that shipped with a 14.4 V pack?

Yes, the battery is rated for both 14.4 V and 15 V, so it replaces the original pack in X450C, X450CA and similar models without voltage mismatch.
