hi guys in need of some wisdom, just tried to start my car but it wont start i have a warning light in red reduced braking etc start car, the clock is doing rounds and wont stop. doing a google search found this may be a battery issue is this correct?

Thanks for your responses guys, i just changed the main battery with a new one car starts fine now decided to change the front one too waiting on the new one to charge up. But i noticed the blower was running i didnt have the car on jumped in the car and yep air coming from the vents came on and off a few times ...thinking this is what killed my battery . Anyone else experienced this?
