A car that I pretty regularly drive everyday has just had it's battery run flat.
I had just got back from a 30 minute drive and 10 minutes later tried to turn it on and it just kept cranking like a flat battery.
I haven't noticed any weaker engine starting but I guess I may have not noticed.
Because I drive regularly and haven't noticed weak engine start recently could this mean the alternator has gone bad?
Edit I have since tried charging the battery and had no luck and have realised thanks to a comment that that was irrelevant anyway.
Edit 2 The car is an 1998 Nissan Pulsar N15 Manual
