Direct replacement for Asus X555 series

This 5000mAh 7.4V 3-cell lithium-ion battery replaces the original C21N1347 pack used across the Asus X555, X555LN, X555LA, X555LD, X555LP, X555LJ, X555SJ, X555YI, F554L and F555L families. It is intended for owners whose factory battery no longer holds a useful charge and who want a like-for-like swap without adapter modifications.

Certified safety protections for daily use

Over-heat, short-circuit and overload safeguards are built into the pack, and the design meets UL, CE, FCC and RoHS requirements. These protections keep temperatures and current draw within safe limits during normal charging and discharging cycles, so the laptop runs stably without unexpected shutdowns or excessive heat from the battery itself.

No extra cables or software required

The battery ships as a standalone unit that fits the existing compartment and connector; no additional wiring, mounting brackets or driver installation are needed. Buyers who need a multi-bay charger, a higher-capacity extended pack or a different voltage should look elsewhere, as this model only covers the standard 3-cell 7.4V configuration.

Questions about this item

How do I install this 5000mAh 7.4V battery in my Asus X555 and what step do people often miss?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector, fit the new 3-cell pack, reconnect the cable, and remember to reattach all case screws before turning it on.

What maintenance will this C21N1347 battery need and when should I replace it?

No routine maintenance is required; capacity will gradually decline after many charge cycles, so replace the pack when run-time no longer meets your needs.

What limit appears first during sustained use of this 3-cell 7.4V pack?

The 5000mAh capacity determines how long the laptop runs on battery; under heavy load the charge depletes faster and the pack will hit its low-voltage cutoff sooner.
