hello all. i have recently purchased the ysd-998 battery and used it for the first time yesterday with my gh2. we filmed a good hour of footage and the battery kept up great. unfortunately my battery did not come with instructions and i am having difficulty with charging it.

i plug the wall adapter in to the 12v hole and nothing happens. no red light appears on the wall charger or the battery while plugged in. when i plug the battery in and i turn the battery on, there is a green light on the battery and the wall charger. is that how i am supposed to charge it? with the battery in the on position?

if i do indeed need to see a red/orange light on the charger, does the battery need to be used beyond a certain threshold? like, since i have only used it to film for an hour, it hasn't used up enough energy for the circuitry to allow the battery to be charged?

any help will be greatly appreciated.
