I got my battery replaced for free. First visit in AS at the end of October. I left it again on Wednesday before Christmas and one week later it was ready. After getting it back, I used battery health app - I got 98% capacity with 0 cycles and... date of manufacturing January 19th 2017 - I thought that if there is constant shortage for last 8-9 months, I will get something more fresh. Anyway I am happy to get it for free.
