This is a brand new Extended Run Acer Aspire One 725 battery. The larger capacity of this battery will cause the battery to protrude to the bottom of the netbook about 1 inch.

We use the highest quality lithium-ion cells and battery components that run longer, charge faster, and weigh less than cheaper, lower quality batteries. Lower quality batteries are made with inferior cells and parts that can wear out in as little as 6 months.

Each Acer battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

If you are replacing your original battery pack, you may have a 4 cell battery pack that delivers 14 volts of power to your laptop. This battery pack has 6 individual cells inside the plastic cartridge which will deliver about 11 volts of power to your laptop.

All higher capacity batteries for your netbook will be rated at 11.1 or 10.8 volts. Your laptop is able to run on variable voltage inputs. For example, your ac power adapter delivers 19 volts of power to your laptop. So whether the input power is rated at 11 volts, 14 volts or 19 volts, your netbook will adapt to the power coming in.

You can expect about 5 1/2 – 8 hours of run time with this Acer 725 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.

This battery replaces the Acer Aspire One AO756 725 series Mini Netbook and TravelMate B113-M series laptop batteries and additional machines which are listed at the extreme bottom of this web page.
