Did you know this kind of thing happens all the time with old studies getting recycled? My buddy runs a small news blog and last year he almost reposted a 2011 coffee study as new until a reader called him out on it. The dates get stripped somewhere in the mix and nobody double checks before it goes live.

Corroded battery contacts will get you every time, no matter how good the gear has been. I've had the same thing happen on a Leica in the middle of a drainage run, screen just died and I stood there like an idiot staring at it. The fix that's saved me since then is putting a thin coat of dielectric grease on the contacts before the cold season hits, it keeps the moisture off and I've never had a freeze-up since. Also, I always keep a spare battery in my jacket pocket, not in the bag, so it stays warm and I can swap it out fast if the main one craps out. The worst part is the drive to borrow something, I feel your pain on that one. Once a unit betrays you like that it's hard to fully trust it again, but the grease trick gave me that peace of mind back.
