i designed reverse polarity protection curcuit for 12 Volt lead acid battery on charger...
do you think it would work?
i think if reverse connection was done......the circuit would have two voltages fighting to control the output voltage and i dont know which would win ?
It is really a nice concept. But when the battery is wrongly connected, there is no need to charge the battery in tricke mode either. Instead the battrey should be completely cutoff from the charger and the user should be warned about the wrong polarity. This simple circuit attched here will do the same with minumum component count.
