I bought this battery for my MSI S12T equipped with BTY-S11 (2100 mAh) She gets up without too much difficulty. My laptop worked seconds before stopping because the battery should be discharged. But no way to load because the laptop does not recognize (it displays "no battery") I think the battery is faulty or there is a problem of compatibility of the ID chip style as on printer cartridges. It will take me to try this on a battery MSI Wind or Akoya 1210 to check. Someone he had this kind of problem?
