Battery charger/maintainer question; This is for all you electronics and engineering guys. I'm just curious, if you have a battery charger or maintainer hooked up and it gets unplugged from the household electrical outlet or the outlet looses power for a long period of time, does it then start to draw current out of the battery and start to discharge the battery if the leads are still hooked up to the battery posts? I have always wondered that if it pushes current into the battery when it's plugged in would it draw the current out if it gets unplugged. Anyone out there know the answer for sure? If it doesn't then WHY? Maybe because of the use of a diode in the circuit? or is there something about how a transformer works? or some other reason?
