Hi,
If the battery blinks 9 times can you still take a drag off it after about a minute or two? If so, you are taking too long a drag off it. The timer on it stops you from going futhure and this is so you don't damage the atty (over heat it).
If you can't take another drag and have to recharge it, then the battery is no good and you need to either call the place you got it from and see if they will replace it or
buy another one..
May I suggest that you should look into an eGo from Janty..
If you can afford a set, get the manual button and this will be the best to get for anyone..
You can see my review here.

They have a 6 month warranty on the entire kit except the cartridges..
Hope this was of some help..
