We use superior South Korean cells inside the battery cartridge that provide longer run times between charges as well as a longer service life than cheaper batteries. This Aspire One mini battery is typically superior to the original battery and is 100% compatible with your Acer Aspire notebook. Each battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

You can expect about 2 1/2 – 4 hours of run time with this Acer Aspire One Mini battery when new, depending on your energy use. If you are looking for even longer battery run times, check out our extended run battery for your Acer laptop (our ACE-1XTB).
