the battery does its job after the original has made around the trackpad and disabled has set. I've taken the trouble and dismantled the thing and behold original apple parts inside. obviously someone dismantled the original batteries and recycle the parts again. I find actually ok. 4 stars because the battery even if the power he was / is only 96% or 97% indicates when it is loaded. but it works. Battery Health indicates an age of 4.1 years, is probably due to that the component can not be reset. Capacity is now for a good 3/4 year at 90%. for the price I find it ok.
