There's probably a BFC in your manual charger, but it is across the high voltage secondary of a ferroresonant transformer. The DC output is the raw voltage from a full-wave rectifier.
yurtle is right about a battery acting like a capacitor.
I got rid of a clipping problem in a el-cheapo guitar amp by splicing in a pair of small 12V Gell-Cells in series across the power supply.
IIRC, it was roughly equivalent to adding about a Farad.
