Replacement battery for ASUS N550 and Q550 series

This 15 V lithium-ion pack replaces the C41-N550 part used in ASUS N550, N550JA, N550JV, N550J, N550X47JV, N550X47JV-SL, N550JK, Q550L, Q550LF, G550, G550J, G550JK and ROG G550 models. It restores full mobility to compatible laptops without modifying the chassis. The unit is supplied new and ready to install.

Grade A cells with integrated protection circuit

Grade A cells provide fast charging and low self-discharge during everyday use. The built-in circuit protection guards against over-charge, over-discharge and short-circuit events, keeping thermals stable and power draw predictable. No additional cooling or configuration is required.

Sustained output at 4000 mAh and 59 Wh

The 4000 mAh capacity delivers consistent run-time across extended work sessions rather than only brief bursts. Voltage remains steady at 15 V throughout the discharge curve, so performance does not throttle as the pack depletes. The pack is rated for long cycle life under normal load patterns.

Questions about this item

How do I install the C41-N550 battery in my ASUS N550 series laptop and what step is often missed?

Power off the laptop, unplug the charger, remove the bottom case screws, disconnect the old battery connector before lifting it out, then connect the new C41-N550 connector firmly and reassemble; the step often missed is disconnecting the old battery first.

What maintenance or replacement will the C41-N550 Li-Ion 4000mAh battery need later?

The Li-Ion pack requires no scheduled maintenance; plan to replace it once runtime drops noticeably or the battery no longer holds a full 59WH charge after many cycles.

What limit appears first on the 15V 59WH battery during sustained heavy use?

The built-in circuit protection will trigger first, cutting power if temperature or current exceeds safe thresholds during prolonged high-load operation.
