I ordered the battery for my Panasonic Lumix G3. Delivery very fast. Within 2 days The battery is well packed in a Verplisterung. After charging the battery plugged in my Lumix G3 - the battery is immediately recognized and the charging status appears on the display of the G3. When battery life I can see almost no difference with the original battery. Have ordered then equal to another Bluemax replacement battery, so long photo sessions nothing stands in the way. The battery, I can recommend as a cheap second battery.
