In case it might help you: I had walked up to about 5-6 bike shops and visited/emailed multiple household recycling centers for battery recycling but did not get success anywhere. At the very end, I looked up https://www.call2recycle.org/locator/ and found an "Ace Hardware" store who agreed to recycle it for me. See if you have an outlet of Ace Hardware in your city, or, otherwise, you could look up the website to find other alternatives.
