Can the chargers be used overseas where the plugs and voltage are different?
The charger is capable of accepting 100–240 V AC, 50/60 Hz and, therefore, can be used overseas with a corresponding regional plug converter.
I have just fully charged my batteries but when I put them back in the charger, the red blinking light comes on. Does this mean they are not actually charged?
If the battery is fully charged and then reinserted right away into the charger, the red blinking light might come on because the battery is already fully charged.
