The build of my new TD42Ti begins. I have a Redarc duel battery system on its way, ARB battery tray fitted. I now need to choose an auxiliary battery. I have always used marine batteries and I usually on get about 3 years out of them. Some shorter. I have been doing a lot of reading and I am still a bit confused. I have done some ringing around and here's the prices I can find (bear in mind I am in rural NSW).

Local battery bloke - $205 - 105ah deep cycle. I think its a Excide

Battery World - AGM $320

Century batteries - $420 - their own brand of AGM

Other battery place - $177 - Hybrid 97ah deep cycle (reckons he sell bucket loads of them with a 2 year warranty)

I am after a sealed unit that I wont need to maintain with a trickle charger too much, if at all. I need a battery that will last at least 2 days to run a Evakool fridge. I would really love some suggestions before I need to buy on ein the next week.

Thanks


Mick
