Even "directly in parallel with the batteries" isn''t really directly in parallel with the batteries, thanks to wiring resistances. The capacitor should have the closest and most direct connection to the load, then this pair should be connected to the battery via wiring which gives you some control of the current drawn from the battery.

High value polarised capacitors typically do not have ideal characteristics at high frequencies (e.g. significant inductance), so it''s fairly common to add a low value capacitor in parallel in situations where you need to worry about stability at high frequencies, as is the case with 78xx regulator ICs such as this.
Initially, a capacitor with capacitance (C_0) when there is air between its plates is charged by a battery to voltage (V_0). When the capacitor is fully charged, the battery is disconnected. A charge (Q_0) then resides on the plates, and the potential difference between the plates is measured to be (V_0). Now, suppose we insert a dielectric that
