Get longer battery life and improved laptop performance with a new Acer UM08A31 battery.

This Acer UM08A31 battery is compatible with the Acer Aspire One Mini Netbook and Gateway LT400U series laptops and additional battery part numbers which are listed below.

We use the highest quality lithium-ion battery cells and components that charge faster and last longer than cheaper, lower quality battery cells. Lower quality batteries can wear out in as little as 6 months. Our batteries can last up to 5 years.

Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your laptop any time without diminishing your battery capacity. This Acer UM08A31 battery replacement is 100% compatible with your Acer Aspire One laptop. Each battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

You can expect up to 4 hours of run time with this Acer UM08A31 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).
