Frequently asked questions

How do I know if this A32-K55 battery is compatible with my Asus laptop?

To ensure compatibility, the most reliable method is to remove the original battery from your laptop and compare the part number printed on it. If it matches A32-K55, A33-K55, A41-K55, or A42-K55, this battery is correct. It is also compatible with Asus A55, K55, and U57 series models. The shape and connector must be identical.

Is it necessary to calibrate the battery the first time I use it?

Yes, it is highly recommended. After installing it, charge it to 100% and leave it charging for 2 more hours. Then, use it until the laptop turns off due to low battery (or reaches 5-7%). Finally, charge it back to 100% without interruption. This process calibrates the charge sensor and ensures that the operating system displays the real percentage of autonomy.

What is the approximate lifespan of this battery?

The lifespan of a Li-Ion battery is measured in charge cycles, typically between 300 and 500 cycles. With normal use, this translates to a duration of 2 to 4 years before its capacity significantly degrades. To extend its life, avoid frequent complete discharges and exposure to high temperatures.

What warranty does it have and what do I do if it doesn't fit or doesn't work?

We offer a 3-year warranty for individuals (1 year for professionals). If the battery does not fit or has any defect, you have 14 days to return it. You can manage the return yourself or request home collection for €8.90 in Spain and Portugal, which will be deducted from the refund. Our technical team will review the case to offer you a solution.
