2005 MK1.5 Focus 1.8 petrol - which battery?

[Blue Oval84]

Hi all, I think I need a new battery in the Focus, can anyone confirm if this-

Is the right type? It's the one that ECP bring up in their search, but I know they aren't always right. I read somehere that these need a Lead Calcium battery, the Bosch in the link above is marked as Silver. But I seem to remember reading a while back that these cars actually need a Silver battery.

Just want to make sure I'm getting the right one before I order! Thanks in advance

Look at your current one for a clue? Or ring a main dealer.

I just bought the Bosch in the end and it seems to have done the trick, no problems so far and the car is certainly starting a little more easily than it did before
