Do you mean physical size ( as Discool says ) or battery capacity ?

072's in both of ours, but not the "standard" Halfrauds 500 CCA and 65 Ah carp :eek:
 
I have one of these wedged in as my main battery:-

1,000 CCA and 130AH - and never let me down.

and then my second battery has just died so have purchased one of these:-

Not sure on quality yet, as only been delivered today, but 5 year guarantee and 77ah & 630cca, should be OK as my aux battery, and price was good too:

Hope this helps.
