Hi, we bought the astra last year in october. We put the car on a SORN notice and havent done anything with the car since. We tried to start it recently and it didnt start. We tried to jump it and it make a clicking noise. We tried to charge the battery but the charger didnt work. I tired to charge it again today but nothing worked at all with it. No lights came on. Not sure whether we need a new battery or try another battery charger?
