"This schematic is for a lead-acid battery charger circuit. I've set up this circuit, but it's only charging at about 15 milliamps. Can anyone help me troubleshoot this problem? By the way, all component values are according to the schematic, except I used a 13-volt transformer instead of a 15-volt one."
I anticipated that the circuit would output an initial charging current of approximately 400 milliamps, which would subsequently taper off to 100 milliamps as the battery reached a full charge.
