I shoot D850, D800, both use EN-EL15 batteries. I shoot a lot and long hours daily, so batteries are critical to my workflow.
So I carry 5 batteries: including 3 older, one newer and one brand-new EN-EL15c. I noticed the older batteries only charge 1/2 way. Three weeks ago I even purchased a new battery trying to make sure I have enough backup battery power.
I’ve checked the charger for anything preventing good contacts and connection, no problems seen. I do occasionally keep a battery charging overnight, but usually I keep a close eye and swap out batteries in the charger.
Now — ALL the batteries charge only 1/2 way. Actually when the charger light turns green, the camera only show 2bars on the charge indicator — that’s ALL the old and new batteries,
So now I have 5 batteries which will only charge less than 50%. I’ve shot for years not having this problem, but now I’m in panic that I’ll not have enough juice for upcoming jobs.
What do you suggest? How can I get a full charge out of the batteries? Can I revitalize the new batteries.
