I need to get a new car battery been putting it off as I'm short of money and I can't seem to make sense of what batteries are what. I know for my 2001 Ford Focus 1.6Zetec I need a silver calcium battery due to it using a smart charge system, which destroys Lead Acid batteries apparentlly, but when ever I look a batteries on Euro Car Parts (I have a voucher) I can't see anywhere were it state's if it is lead acid, silver calcium, etc. Can anybody help me out, I've type my reg in and these are some of what they have given me.

Thanks for your help in advance.
