Battery problem

Hi,
For acer 9410 you have 2 options for battery. an 8 cell battery which normally would last for 3.5 hrs. or a 6 cell battery that lasts for 2 hours. but that would depend on the application that you are using. for example, the battery will last longer if .you are just using it for email or chat compared to watching video. Why is that? its because watching video and playing games requires heavy processing thus consuming more battery. we should also remember that rechargeabu le batteries are consumable parts. it runs out in time. it is normal for it to degrade after a year. if it has'nt been a year since you purchased this computer then call acer and ask for a replacement battery. hope this helps?
thanks.
