Which car battery?

[Dg83]

Hi all, I'm new here and hoping for some advice please...

I'm just wondering if anyone in the know can advise whether I'm better off getting a Bosch S3 008 or Bosch S4 002 for a 2014 Zafira?

Cost wise much of a muchness (£64 versus £70 - can't remember which way around but for the difference, would rather the better battery).

The amp and CCA ratings appear to be higher on the S3 but I've seen others saying any S4 is better than an S3.

Spec details...

Bosch S3 008
12Volts
Technology Wet
Capacity (C20)70 AhC
CA (EN)640 A

Bosch S4 002
12 Volts
Technology Wet
Capacity (C20)52 Ah
CCA (EN)470 A

Any advice welcome.

Thanks in advance.

It's a petrol- sorry should mentioned that.

So would you say S4 as petrol? Also does it matter about amps being higher on the S3?

Thanks!

Thanks for all your help. Went for S4 from Costco on end - very good value! Cheers again!
