The battery fits perfectly into a X200. The term after recalibration is ok but can compete with the original not quite. At relatively low screen brightness and WiFi turned on, the battery manages to keep 4h through. The original battery is as powerful as early as about 20%. Nevertheless, the price-performance ratio is very good. The value of the battery is good. So who has not in the last minutes of battery life with this battery angkommt well served. The original battery has persevered with me 3 years, I hope this battery creates the well.
