In the circuit involved charge conservation is only used to write Kirchoff Current Laws. For any two terminal device, this means than a charge q1 flowing into terminal 1 is equal to the same amount of charge q1 flowing out of terminal 2. It may seem funny, but a capacitor does not store (net) charge. As soon as both "charged" are connected in series, some positive charges are annihilated by the same amount of negative charges, leaving the same net balance, i.e. zero. Pere
