Yep, fig 3. Any high value, superimposed AC currents will heat up the battery signifantly and unnecessarily.
EDIT: (Unless you want to pre-heat the battery in wintery conditions).
Low frequency pulse charging can be used to replace the V portion of the usual charging profile. It will also reveal the battery response to a step function, allowing monitoring equipment to detect an imbalance.
