If one put a switch in the charger cord, would leaving the charger plugged in but turned off with the battery in the charger have the same effect as removing the battery from the charger?
Ok, thanks. The charger appears to be drawing current when plugged in with the battery removed, or with a battery in it which has been fully charged. Presumably it does this as part of the detection circuitry for the insertion/removal of the battery. Is there any reason NOT to put a switch in the cord to prevent this waste?
