I get that with my EBL charger but they show as full, then I take one out and put back in and it flashes.
They last me a week or more though with frequent use so i'm cool with it. If they cause any issues will get a better charger and some Ladda rechargeable from IKEA as they are supposedly rebadged eneloops.
I got that other day. All charged fine but when I put in controller it was already missing a bit of charge. I think it said in the manual they get better after a couple of charges though.
