First I have to say it seems you have a small connection problem... try changing the charger for another one or your connector . 10V with and adapter heads at Walmart for $9 dollars. Then see if it's the actual charger.. if that fails then you know it's the connector on the video camera and you can bring it for repair to a local fix it place those parts are cheap and easy to change. Takes about 20 minutes to change.. and thats after having a cup of coffee for 5 minutes.
I personally would buy a seperate charger for $29.99 and just have a rapid charge of 30 minutes for each batterie lasting 2 hours afterwards... Shower and shave and it's all ready.
