If your controller is less than 8 or 9 years old then yes. If you want to check, see the below instructions to see if your controller has the matching T-9 ""Cell Type"" setting. Keep in mind though that bigger is better, the T-15 just means your system will work less hard to do the same job and will last you longer.
