Battery ring spotlight camera

My Ring spotlight camera is not turning on... I recharge the battery fully until green light is on. Insert into camera - nothing happens. Tried holing 'setup' button but noting turns it on. Light beside battery bay is solid colour for about 1 day then it is flashing the next day indicating the battery needs to be recharged, after 3 days battery bay light is off. Is it a faulty battery? Happy to purchase a new battery but don't want to get it then find out it is the camera that has the issue not the battery.
