This is a brand new Extended Run Acer replacement battery. This long run battery will run at least 50% longer than the 3 cell battery that ships standard with your laptop. This battery is going to be physically larger than the original. The extra power cells will cause the back of your laptop to tilt up slightly, allowing for better air flow keeping your laptop cooler. The added run time is achieved with an additional 3 cells inside the cartridge. Users of this battery pack experience an additional 1-2 hours of run time over the standard battery. Estimated run time with this battery is 3-5 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness. The superior South Korean cells inside the battery cartridge will provide longer run times between charges as well as a longer service life than cheaper batteries. In addition, 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 laptop battery replacement is typically superior to the original battery and is 100% compatible with your Acer laptop computer. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

The additional cells contained in this battery will protrude to the bottom of your laptop about 1 inch and add about 5 ounces of additional weight. The added height will also provide more space for air circulation and cooling underneath your laptop. The battery is designed to fit perfectly into your laptop and includes rubber feet which will rest on your table surface. Not all computer batteries have the same capacity and run times. The higher capacity battery cells inside this cartridge have an energy capacity of 4400 mAh.
