I opened my acer laptop up to clean the fans and to my surprise I noticed a 3 cell battery (see photo) when it's supposed to be a 4 cell (15.2V 48Wh). I've also searched for my SNID (NXHMZET0029XXXXX) in the official website as a confirmation. Moreover, several youtube videos confirm that the original battery, as stated in the website, should be 4-cell.
I was planning to replace the battery as it drains quite quickly (machine is 3 years old). What am I supposed to do? 11.4V 3 cell battery or 15.2 4 cell battery? Should I complain to the Support Center or not worth it considering the two year limited warranty has already expired?
