My car wouldn't start as if the battery is flat, so got a jump start, drove 1 min and it just cut out again. Was about to get my friend to tow my car when the inside light came on, so started the car and was able to drive it home 10mins away. Checked the battery connections and cleaned the terminals but the car still won't start now. When I turn the key the dashboard lights flicker and there's a little click sound but nothing else.
Do I need a new battery or could it be the electrics in my car? What else could it be?
