I think you mean "warranty". If you go into battery health in settings it'll tell you the maximum capacity. If it’s at or below 85% or says service, it’s probably due for another replacement. You can order kits to do it yourself here on ifixit. Or if you would like you can take it to a local shop and they’ll be more than capable of getting it done faster and in some cases cheaper. Try to avoid the big chains, especially batteries plus if you have any of those around you. They use cheap Rayovac batteries that tend to fail.
