Have the battery While only 10 days in use, but the purchase appears to have been well worthwhile. The battery is on time criticized within 2 days eingetroffen.Die precision fit, in other replicas often, is absolutely ok. After initial test runs so like 3 hrs. Use be possible. But half an hour less would be ok for me, especially since the original cost many times over. Because I would rather think about a second battery, which is then charged a precaution carries in his luggage. Then you would have capacity approx. 6 hours for still less.
