Cold Cranking Amps, different standards, en, sae

[ajg]

I've just bought a new battery for my 400 Chimaera. The battery recomended in the bible is a 072 with cca (sae) of over 700A, the battery I have bought is a 089 (supposed to be a replacement for the 072) but has cca of only 480A but (en) instead of (sae).
Is 480A (en) equivelent to about 700A (sae)?
I suspect that the battery is not up to the job as since replacing it, sometimes the engine is very slow to start turning over.
Does anyone know what the difference is between sae and en standards?

See you at pistonfest.

Thanks for the advice, I'll check all the terminals asap. I've since noticed that sometimes the alternator stops working and the battery voltage will drop to 12.5V with engine running, hopping this is also caused by a loose conection as well?
