I'm up for a new aux in my GU and the old ones going on the ute.

I'm looking at an optima d31a but I'm worried about the extra weight on the wheel arch but the extra AH would be nice, who's running Agm or gel batts under the bonnet? And how longs it lasted?

I have a feeling the first link will be cheaper as the last batt from all purpose batteries was around 40$ postage

Or should I go a lighter/cheeper lower AH one in the range like the http://www.optima-batteries.com.au/o...top-d3478.html

Any one know where to get the optima range cheeper?
