I brought the flat battery to a nearby garage and got it charged up for free. unfortunately the voltage started dropping gradually once off the charger, reducing from 12.5V and stabilised at 8.3V the next morning. got a new battery installed today and the car is now starting fine. The alternator appeared fine as the voltage increased to approx. 14.5V when the engine is running.
