I believe if you have breakdown cover with the RAC they will fit a new battery for you - but you must pay for the battery and I would expect it not to be cheap.

Your cheapest option would be to shop around on the internet, get one delivered and fit it yourself, or, if you can charge the battery it may hold the charge for long enough to get it started; you can collect a new battery from somewhere and fit it yourself. If you go to Halfords they will fit one for you; you will have to pay for the fitting and their batteries are not the cheapest.

Probably the most expensive option would be to get the car to a garage and get a new battery fitted there.

You will have to decide which is right for you.

One internet site gives £35 incl.delivery for a petrol (not diesel) Ford Ka.

No idea what this firm or their battery is like.

Halfords - cheapest: £45, fitting from £9.99.

No idea about RAC prices - you could ring them. No idea either about the garage option. You could ring whoever does your servicing and ask them.
