Frequently asked questions
How can I be sure this battery is compatible with my Asus laptop?
To confirm compatibility, the most reliable way is to check the part number of your original battery. Disassemble it and look for a printed code, such as 'C21N1509'. If it matches, this battery is the correct one. You can also verify your laptop model. This battery is designed for the Asus X556UV. If you have doubts, contact our technical support with both pieces of information.
Is it necessary to calibrate the battery the first time it is used?
Yes, it is highly recommended. To calibrate it, charge the battery to 100% with the laptop turned off. Then, turn it on and use it on battery power until it is completely depleted and the device shuts down. Finally, recharge it to 100% without interruptions. This process helps the system recognize the actual capacity of the new battery and display accurate charge percentages.
What is the approximate lifespan of this battery?
The lifespan of a Li-Ion battery is measured in charge cycles and typically ranges between 300 and 500 complete cycles, which is equivalent to about 2-3 years of typical use. To extend its life, avoid frequent full discharges and exposure to high temperatures. Maintaining the charge between 20% and 80% is good practice.
What warranty does it have and what do I do if it doesn't work or doesn't fit my laptop?
The battery has a 3-year warranty for private customers and 1 year for professionals. If upon receipt it is not compatible or has any defect, you have 14 days to request a return.
