Yamaha Motor India — Battery issue - request for replace battery

Hi I'm sundarraj, I'm bought and using Yamaha fz-x from 04.10.2021 but I'm facing battery issue most of the time. if I'm don't use bike for 2 or 3 days, battery gone dry while try to start the bike on 4rth day, it is not starting. Due to not having manual kicker, i need to run and push the bike to start.
Note: Already informed the person who serviced. From the second service itself i am asking for solution but they are telling to ride the bike for 15km to 30km everyday to avoid the battery dry. When I consult with the another service person he mentioned this is not the correct solution. He told to check the battery.

Please replace the battery, hope the charges will take care in the warranty.
