Replacement battery for ASUS X550 series

This 4-cell lithium-ion pack restores portable runtime to compatible ASUS X550, R510, K550 and F550 laptops that use the A41-X550A part number. It delivers 2600mAh capacity at 14.8V for 44Wh of energy. A built-in smart control chip manages charge and discharge cycles. The unit is supplied new and ready to install.

Sustained discharge with premium cells

Premium-grade cells and the smart control chip maintain stable voltage through extended work sessions rather than only short bursts. Overheat, short-circuit, overload and overcharge protections guard the pack during continuous load. The design targets over 1000 charge cycles before noticeable capacity loss. Indoor and outdoor use is supported by the safety circuitry.

Upgrades worn original batteries

The pack replaces an ageing A41-X550A or A41-X550 battery that no longer holds a useful charge. Verify the part number printed on your original unit before ordering to ensure correct fit. Buyers who need a higher-capacity pack or a different voltage should look for an alternative model. The 12-month warranty covers defects in materials and workmanship.
