Camera arrived...glad to say there is no problem with it yet. A question has arisen regarding the battery...the manual says that the battery needs to be fully discharged for extended storage, but doesn't say how to discharge it. Do you know of a safe and practical way to do so? Also while on the battery, I thought it might be good to have a spare, but looking at the listings on Amazon and eBay, it appears that not all NP50 batteries are the same. One ad on eBay has a model selection drop down field, with a variety of models available, but not the XF-1. The pictures all look exactly the same, except some generic ones. Is there really any difference otherwise?
