Do Apple stores have online text chats or e-mail addresses for online communications?

Is there a community forum for Apple's retail stores? I wanted to ask if Apple stores have online text chats or e-mail addresses for online communications? I wanted to ask them if they had batteries in stock to replace before making appointments and going in. I tried texting (no blue color for secured iMessages) the store's phone #, but no answers. Online generic (shopping and technical support) chats couldn't help with this part. I also have speech and hearing impediments so I can't call them. :(
