an auto-electrician told me that most dry-cell batteries have a high CCA rating, but thats usually for only the first 15seconds. After that the CCA drops to a lower number. I was advised that a heavy duty wetcell battery would be better and cheaper as it holds a higher average CCA.

Any truth to the above statement?

I work for a battery company and no battery would be put into a car for audio or starting application as a dry cell...all batteries need battery acid to operate thus making them wet but yes a high CCA rating or cranking amps rating is reccommend for starting cars not to run auxilary power units such as audio units...i would be looking into AGM (absorbed glass mat) or GEL batteries you can get deep cycle versions that will last the distance go and check out www.alcobatt.com.au depending on which state youre in im sure they will have a supplier near by.

Optima D34 (Yellow Top)

Can't beat it

Another vote for Optima yellow top here. Never had a problem with my audio system (though it's by no means 'killer'). Recently the turbo died and the car was was sitting in my backyard for about 2.5 months without being touched. The battery had run flat enough that it wouldn't crank over, but after 1.5 days charge it started no worries. Ppl tell me it should continue to work fine from now on, hope so - impressed so far.
