I just found a box of old crap from high school (which was close on 30 years ago), which included my old scientific calculator which I used in maths & physics. It didn't work, so I opened the back up to find some old Kodak brand batteries which were well-covered at each end with white salts (a sure sign of corrosion). On second thoughts, I may have used this device at uni a little over 20 years ago...
I removed the old batteries, scraped off the salts with a screwdriver, and replaced the batteries and the device now works fine... although my kids don't know why it doesn't have a touch-screen...
Questions: at what point (if any) does a device fail from battery corrosion? Can the batteries be salvaged in any way (I doubt it)? Is there a way to remove damage? Obviously removing batteries prior to storage is key, but what if we come across an old, corroded device?
