What else could it be? It works good on AC power - works bad on battery.
The reason the battery lasts 5 hours is that it's not powering the LCD screen which sucks a lot of power.

How much did you pay for your last battery - and where did you buy it from?
What is the date of manufacture listed on the battery.
 
Trying running an operating system other than Windows.
You can download and burn a 'LiveCD' with Ubuntu linux OS for free.
Just boot the LiveCD and it loads a the whole Ubuntu operating system.
If that is also running on a dark screen while on battery you're ruled out any problem with the OS which leaves only hardware as the problem.

Find the Get Ubuntu: Try it on a CD or USB stick option

 
Can you explain why you think this means it might not be the battery? (the current battery, the prior batteries, etc).
