I ordered the battery of my Asus laptop and it works! X64JV. I can not say about my first attempt with another battery from another seller. He held the first test 1 3/4 hours and that's certainly better than my broken battery. Small drawback: The battery is very difficult to rein in the laptop, I had to push and push already properly. But at least for a new battery for 30 instead of 180 by the original manufacturer, I am satisfied with the result.
