Buying a smaller battery for C180

[MrRauf]

Hi everyone

My car battery has totally died and would not start with jump leads. As I am planning to sell the car I am looking for a cheap battery. I came across this one at Euro Car parts - Lion Battery (Battery 027 3 Year Guarantee):

Lion Mercedes-Benz Battery 027 3 Year Guarantee | Euro Car Parts UK?s No.1 Car Parts Retailer

Its smaller than the battery I currently have on my w203 C180 however will it do the job?

Thanks in advance
