This has probably been answered somewhere, but i'm feeling lazy. Anyway i was recharging my NP-F975 knock-off, and one of the little metal sleeves in the power connector stayed with the charger when i took the battery out. Can I just pop it back into the battery and go about my business? Or will that direly fuck something up?
That's one of the reasons I tended to keep the same battery in the 7xx and recharge with the built-in charger.
I have read of people holding those sleeves in with a bit of glue. Superglue should work, or epoxy. Don't get it in the metal sleeve, of course.
That's what I normally do too, but i had to charge two batteries this morning, and wouldn't you know I put the main battery in the charger.
