Hello,
We have (2) HP Pavillion G6 Laptops, having purchased both about 2-3yrs ago.
We always use them on mains power, only use the batteries when the power goes off.
(This enables us to watch a DVD or listen to a CD, when we have nothing else to do, while the Power is out.)
We keep them fully charged in case of emergency.
If we are going anywhere we take the Laptop with us on battery, but usually try to run it on power while away.
We have also found that the batteries do not last as long as they should, only last about an hour or so.
However, they do retain the charge, when not in use.
