V3 1500mAh battery - first impressions

got mine from Germany (look on ebay.de) ...came sealed in plastic ...branded "MaxxCell" and says "up to 1500mAh" on it. Charged in desktop charger overnight. On first charge, already over double the duration with my normal usage. Only thing, the plastic over the top edge hangs on the clip inside back cover. I cut that away (about 1mm of stuff around 3mm wide) and seems easier to insert/remove. Will update as I use it.
