Why does a battery have high cranking amps but low Ah?

bamberg · May 17, 2014

Hi, I'm new here. Hoping there's somewhere there can help with a battery question.

An Odyssey PC1500 with cranking amps of 1500 seems like a mighty powerful battery but why is it only 68 Ah rating. I thought this rating should be high, like 110, say. there's something I don't understand. Please can you explain the importance/significance of this Ah figure, particulally with regard to the Odyssey PC1500?

Also, is this battery for starting, for auxillary stuff, or both?

Battery construction

that size would be okay on 2.0petrol generally.

cold cranking amps important, but larger batteries are generally lots of electrical accessories which may be ign on engine off or bigger capacity for lots of stop start between decent run
