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?
 
Here's some shpiel off the website for you. They are very popular for hardcore off roaders, used as a starting battery and as a deep cycle battery for winching etc.

Phenomenal starting power and massive deep cycle reserve power in one battery!

Some batteries provide enormous cranking power. Others, deep cycle reserve power. The revolutionary ODYSSEY® battery is designed to do both.

How is this possible? The answer begins with flat plates made of 99.99% pure virgin lead - not lead alloy. Pure lead plates can be made thinner, so we can fit more of them in the battery. More ODYSSEY battery plates mean more plate surface area. And that means more power – twice as much as conventional batteries.

In fact, ODYSSEY batteries are capable of providing engine cranking pulses in excess of 2250 amps for 5 seconds – double to triple that of equally sized conventional batteries, even at very low temperatures. And they can handle 400 charge-discharge cycles to 80% depth of discharge.

This extreme combination of power and performance makes ODYSSEY batteries perfect for a range of applications, including automotive/LTV, marine, commercial, and powersports. Designed and built to last up to 3 times as long.

Thanks to rugged construction and AGM (Absorbed Glass Mat) design, ODYSSEY batteries have an 8-12 year design life and a 3-10 year service life. Welded intercell connections enable it to withstand extreme vibration, and AGM design holds acid in place to prevent spills, even when installed on its side.

And unlike conventional batteries, ODYSSEY batteries can be stored for up to 2 years and still be returned to full power (at 25°C (77°F). Storage times will be even longer at lower temperatures.)

im no expert but CCA and Ah are very different measures of a battery.

CCA is the ability of the battery to throw out large amperages in a short space of time. You need plenty of this to start and engine.

Ah is the measure of how long a battery can support a set load. You need plenty of this to keep things like a fridge running.
