I need some advise please, my Ford Ka's battery died a few weeks ago ( one cold morning) so I purchased a new one.

It's been fine until this morning (cold and frosty) and it wouldn't start again:

Nothing was left on overnight

Engine didn't even attempt to tick over when I turned the ignition


Can someone offer some advice?

Thank you!

 

it could be a duff battery....
otherwise check for current with ignition off etc across fuses
also check bootlight/glove box light go off if fitted

 

An easy way is to measure the draw whilst removing fuses, that way you can isolate it to a particular circuit. A good place to start is looking at the radio.

As said above, radios on these go tits up and cause a drain. Try pulling it out and unplugging it for a few days see what happens.
