I am trying to build a generic circuit to detect different types of batteries (lithium ,lead acid etc) based on automatic and quick tests for a potential product.

Is this possible using an mcu and and electronic circuit?

It should be possible if the battery is not in a defect or deep discharged state. Based on the initial voltage and a defined discharge you can determine the battery type. The discharge curve looks very different for different chemistries. I have seen lately on Ebay a device that measures the battery capacity. If I am not wrong it also determines the battery chemistry. So it should be not too hard to figure it out.
