Batteries & cells events

DIYguru Events is mostly a directory. Almost every listing is run by the organiser named on it — trade bodies, universities, exhibition companies and OEMs — and “Participate” takes you to their own registration page. Events marked DIYguru event are ours, and you register for those here — see just those. How this works
