Quick delivery, product just as ordered. While replacement isn't a 5 minute snap, the battery itself works great once you remove 22 tiny screws, remove the back of the Acer laptop, unplug and replace the old battery, and put everything back together again.
Perfect fit for my Acer Aspire E15. Replaces the old manufacturer battery that couldn't hold a charge. The voltage and wattage are slightly different, but I haven't had any issues yet.
