Battery for Qucs

Thread starter #1
I'm new to this stuff and would like to learn by trying something simple I want to make, a car battery charger.
I'm stumped at the first hurdle because I cannot see a battery symbol as a destination for the DC.
I notice that one BobW created missing crystal by building one out of discrete available components.
Does anyone know how to great a lead acid battery using available components?
If so can the items be grouped to create new item for insertion into new circuits?

Should I continue learning Qucs or is LtSpice a better option?

Not really the answer you are looking for, but it is one thing to learn electronics, and yet another to learn to use a design tool package. If you look up 'battery equivalent circuit' on Google you may find what you are looking for. It's a good idea to think about what you find in relation to what you know about a real battery. For a battery onlad it is essentially a DC source in series with a resistor (internal resistance) but when being charged a capacitor with resistances. It can get more complicated dependant on how far you want (or need) to go.
