The spare battery has nameplate only 1000mAh (ie 30% less than the much more expensive original battery), but holds around 90 min. More is at my original battery long no longer there. The dimensions correspond exactly to the original, which at several Replacementaccus bearing the same name (VW-VBG130) unfortunately can not be said. My HDC SD5, which leaves only a tailor-made battery into the bay, is dependent on it. The battery remaining indicator is reliable with me. Clear recommendation!
