Well, I have an Acer Aspire 5520 since November 2007, I love it. :D
Except... the battery only lasts 1:30 hours... before it lasted 2 hours... what's wrong?! :confused:

I never used the battery much, I always used the laptop with only the AC charger...

I let it charge for 1:30 hours (hmmm... that sounds familiar :p) turned off, until the orange light of the LEDs changes to green... or should I let it charge for 2 hours?

Anyway, do I really need to change battery? They're expensive and I only can find them online and I don't want to shop online.

Well how long a battery last depend how you actually use your laptop when in battery mode...if there is heavy cpu load, graphics card load it may shorten the time, playing games short also the time...in standby mode it may last longer is something difficult to actually calculate...also don't forget Lithium batteries begin losing their charge since the day it get manufactured, and not when it first is used...so if you think your battery is dying even in standby mode is getting wway less then it should be then you have to buy a new battery.

Also I heard that if you keep your battery on charge when it's full. That can also limit the battery's life to. So I at times take the battery out, and then just use the mains.

^ Well not entirely true, as soon as a the battery get charged the computer will switch to AC power so it won't really affect, but its true that we should take out the battery because of the temp the battery is been exposed when the laptop get really hot in which shorten also the life.

I don't play games, I usually use this laptop for browsing the web, hear music, and MSN.

Well then i guess is dying... you can still squeeze some more time reducing the LCD backlight to the lowest and using the OS powersave profiles

In the window where you choose your screen saver or right click desktop > proprieties go to screen saver tab, then click in "power..." button and you should see "power schemes", in there just use choose "Minimal Power Management" when in battery mode. Now the cpu will only run at full speed when needed. In AC mode choose "Always On". Also in your nVidia control panel you should also see a power savemode too it will also lower your GPU performance to increase battery time.
