Not necessarily. This laptop model uses two different batteries, C21N1706 and C21N1624, which are not interchangeable because they have different connectors. The only way to be sure is to open your laptop and read the part number on the label of your current battery. If it says 'C21N1706', this is the correct one. If it says another code, it will not work.
This is an internal battery, so it requires opening the laptop.

If you do not have experience, we recommend that the installation be carried out by a technical service.
