First off, why did you have to charge battery? Then see if correct voltage gets to starter relay/solenoid and then to starter. Is there a fuse blown? Check basics first.

If the battery died the sync between the DME (Engine Control Module) and EWS (Immobilizer) could have lost. It requires OE or OE capable diagnostic computer to re-synchronize the modules.
The engine's computer needs the "Start Authorized" signal from the immobilizer.
Of course there could be other problems also, but this is a common with battery failure.
