Digital Nc High Capacity Replacement Intelligent Battery Compatible with Panasonic DMW-BLF19

One didn’t charge at all when I received it. The second one did but after one day of use I left it on charge overnight and now it’s like the first one. Original Charger doesn’t recognize it anymore. Same for a third party charger. The 3 original Panasonic batteries I have are still fine.This will teach me to buy original batteries and not cheap clones :-/
