What this battery replaces

The PISKEKAT C21N1347 is a 7.6 V lithium-polymer laptop battery rated at 5000 mAh and 38 Wh across three cells. It is built as a direct replacement for the Asus part numbers C21N1347 and 2ICP4/63/134 and fits the X550, X555, X555LA, X555LD and X555LN series notebooks.

Who it suits and who it does not

Owners of the listed Asus models who need a new 7.6 V pack with built-in circuit protection will find this a compatible match. Buyers whose laptops require a different voltage, a higher capacity, or a different physical form factor should look elsewhere.

Capacity and practical runtime

The 38 Wh rating delivers typical mainstream notebook runtime for web browsing and office work. Heavier workloads such as sustained video playback or gaming will drain the pack more quickly, and the 500-cycle design life means capacity will gradually diminish after extended daily use.

Questions about this item

Does this C21N1347 battery require any extra cables or adapters to install in my Asus X555LA?

No extra cables are needed. The pack uses the original 2ICP4/63/134 form factor and plugs directly into the laptop's internal battery connector.

Will the 7.6 V output work safely in my older Asus X550 that shipped with a 7.4 V battery?

Yes. The manufacturer states the 7.6 V pack is compatible with 7.4 V systems, and built-in circuit protection maintains stable operation.

How can I verify the battery is delivering its rated 5000 mAh capacity after the first few charges?

Run a full charge–discharge cycle in the OS battery report or a tool like BatteryInfoView; the reported design capacity should read 38 Wh (5000 mAh at 7.6 V).
