Depends on the form of the calcite, the dilution of tha acid etc. but in the past when I've stuck a drop of HCL on a lump of limestone it bubbles up immediately and unmistakably. Never used battery acid so can't comment on this experiment's result. That is why geologists carry a small bottle of HCL in the field and have done for centuries. It works to identify carbonate in the manner described.
Cheers
