I wonder if anyone has any experience of, or can suggest a solution for, a 4iii non-drive-side crank power meter eating through batteries like there's no tomorrow? I bought this meter secondhand last year and it's been good as gold until the last month or so, now it needs a new battery every time I go out, it lasts fine in use (6 hours being the maximum ride since the problem started) but when I go to use it again the battery's dead or at best lasts half an hour then dies.
