Your car already has a rechargeable battery: the lead/acid automotive battery that powers the electronics (including the stater motor) when the engine isn't running.
I think he wants to build one to replace the one in his car.

In addition to orksecurity the battery you have has a lot of capacity and can provide a lot of current. Is there something specific you want to run that isn't connected to the car's 12V supply?
