The performance of the battery corresponds to the original, the durability I can not say anything yet. The charger works, but the charger is made VERY inaccurate, so you really have to fumble to insert the battery so that it is loaded (LED turns red). If the given charging elapses normally.
However, the total set (2 batteries and charger) is cheaper than a single battery replacements, so you can accept the fumbling.
