The majority of garage door opener transmitters taken the smaller circular lithium batteries instead of the larger AA or 9 volt batteries. The lithium batteries are expected to last approximately 5 years so should last long than the other type batteries but like any battery they will eventually die and need to be replaced.
The chart below lists which battery the individual garage door transmitters take by brand and model and which years the different colored smart buttons were made and used. While many of the current popular ones are listed it's not an all inclusive list so if your brand or model isn't listed below you may have to refer to your owner's manual or open the transmitter first in order to determine which one you need for the replacement. Make sure that any time you replace the garage door remote battery that you are using the correct one by number and not substituting others that are the same physical size.
