Works perfectly with my Acer Aspire E5-575G-55NW. The battery is not fully charged when it is shipped so you have to charge fully before using it for the first time. Backup time is really good, nearly 3Hrs. Hope this will last as my original battery(LG Chemicals- Acer Branded) got damaged(2 Cells) within 2 years.
