I bought a new 1100 mAh battery, plugged it into the charger the light on the battery flashes a couple of times but the light on the charger stays green indicating charged. So either the battery is full charged or its a dud. Any ideas?
Do new batteries come charged?

The types of batteries that we commonly use do not have a memory, so the 8 hour thing is pretty much just a myth from the past. The exception being the 5v NICD batteries which need to sit on a charger for 8+ hours before being used.
Batteries should always be in a "partial charge" state when stored, not fully charged or fully drained, and that should be the way you find any new rechargable battery when you get it.

I've received a lot of electronic cigarette batteries that came fully charged.
I've also received a lot that did not come fully charged.
Some places charge them, some don't.
This has been my experience also.
Try using it for 15-30 min and then put it on the charger, if it shows charging then it was fully charged when you got it.
That's what I thought too, but I just received a new battery pack with a Lithium-Polymer battery with a USB connector for charging and one for output which is used to charge any device you can charge using your computer's USB port and it said to charge it for 8 hours the first time.
I always though chargers for Lithium-type batteries would cut off after the battery reaches full charge no matter how long it takes. So, if a battery takes 2 hours to charge, what is it doing for the other 6?
Sitting there wondering if it should charge more
Actually the charger gives it a thump every so often to see if it is fully charged.
Some of the old Ni-XX battery chargers would go into trickle-charge mode after the main charge cycle cut off, usually around 95% or so charged, to finish charging and top it off to 100%, but with Lithium-type batteries this isn't necessary. Once a Lithium-type battery reaches 100% charge the charger cuts off totally. Theoretically you can leave the battery in the charger indefinitely with no additional charging taking place (however, in reality this is not recommended).
Oh, well... As the saying goes; right or wrong, follow the manufacture's instructions so you won't void the warranty.

Most of the chargers we use for eGo type batteries will turn off charging the battery when it has the correct voltage. If the light is green, it doesn't matter how long you leave it connected, it is no longer charging. Green light is the Off mode and no power is running into the battery.

Ah, yes, Basic to Advanced Battery Information from Battery University, the best place to find what you need related to batteries... 
If the battery is showing that it is charged, it's charged. I will try charging batteries when they arrive, some need charging and others don't. It is safe to top off a battery.
