It's not a Sony(R) Brand. Just want to get that out of the way first. It's not too bad for the price. The charger gets the job done and have no problems with it so far. I do have a slight problem that the charger seems very light-weight and flimsy. The battery itself is not Sony(R) brand as well. It does last around 7hours, roughly 5 hours because of my CFW plugins.
