Mova robotic mower turns on briefly then turns back off after few seconds

Hello, I am having trouble initializing the mower. If I turn it on it gives the greeting message "Welcome to Mova Robot" then shuts down after 2-3 seconds. I am considering replacing the battery but not willing to spend the money if this will not solve the problem. Did anyone else have this problem and how did you address this issue.
