Car electrics failing / no power

When turning on the ignition there's no power at all in the car, the dashboard isn't lighting up and the car won't turn over.

Battery's terminals look corroded

Battery has bluish powder around terminals

The battery terminals where the leads connect to the battery seem to have a greeny blue powdery substance all over them.

Engine doesn't start up and/or cuts out when running

The engine doesn't start up very easily and will often not start at all. When it is running it can cut out completely without warning.
