I have about 10 batteries...many are over 3 years old (from my Canons pre-mirrorless)
Before a trip I charged them until green on charger. I then put in camera, and it shows 100%. On trip it fails after less than 2 hours of shooting.....then into controlled trash.
Any way to test real remaining life outside of the camera so that I might cull the weak batteries?
Thanks
I have a couple that are 8 years old for my Nikon. One Nikon & one ProMaster. The ProMaster is just about kaput. But the same thing. Shows full but really doesn't last that long. The Nikon is showing its age but is still a pretty good backup to a New Nikon purchased about 6 months ago.
I think you should probably move on if they don 't get any better after a charge or two. Charger any good?
