AGM Battery - Deep Cycle of General?

Peter,
We just bought a second hand Cape York deluxe Explorer from Paul @ OzRoamers and are now getting another fullriver 120ah agm installed. These will go in the back to move weight behind the axle, as one is on the drawbar. We haven't used the camper just yet as it is still at Noosa getting things done to it so I can't give you info on how long they will last sorry.

Deep Cycle Peter.

Deep Cycle batteries are designed specifically to enable a consistent current draw to lower levels than a conventional battery.

Hi Peter McG, before you buy any specific AGM battery do a lot of research on the brand of AGM you are looking at.

Try to base your research on how you think you are going to use the battery.

There are MAJOR deference's between AGM brand types with the USA made AGMs being more expensive but more likely to last longer and tolerate abuse better than the cheaper Chinese made AGMs.

Cheers.

Peter, I've got two 120AH Fullriver AGMs on the CT. One is about 12 months old, the other 9 months. Can not fault them. Apart from camping use, I regularly pull one out to run the electric motor on our fishing canoe.

Perhaps (??) you will get a better battery paying $100 to $200 more for another brand, but so far, I reckon these are the bee's knees. Time will tell. Paid $300 each for them. They are heavy suckers though at 35KG each.

Going by the graphs on the FullRiver website, (which are in a laboratory and therefore theoretical) there's supposed to be approx a 25% improvement in cycle life with the DC series Vs the HGL series.
I went for the HGL series because...
1. It is about 5Kgs lighter (multiplied by 2 as I have two 120 A/h batteries) and
2.The price difference (which would vary from supplier to supplier) did not justify the extra cycles.
In any event, batteries often die as much from age as cycles, so I figured I'd go the HGL and replace them a bit sooner.
I'm very happy with them so far (1 year old)
Cheers

Peter McG,

Talk to Tony at Offroad Obsession, I recently went through the same thoughts and chose the DC90-12 from Fullriver ($300.00). You might the battery a bit cheaper than that somewhere else, but Tony gives good service and will look after you. The deep cycle is meant for cycling applications and is the battery that you should use in your camper. For the sake of an extra $30.00 over six years or more for the expected life of the battery I thought it was the only way to go.

The HGL is more of a hybrid battery, but still has a 90 ah rating with enough cca to start moast cars.

The DC searies proberly doesn't have quite as much cca, but this is the trade off for the longer cycling life.

I have three auxillary batterys, 190 ah 1300 cca, 100ah 750 cca and now the new fullriver agm. Having enough cca to start the 05 diesel hilux was never an issue for me. Jump starting when/if the main was flat was the only reason I could think of for choosing the hgl instead of the dc.

All of my batteries will be replaced with the fullriver dc's when the begin to fail.

The Lifeline brand of battery is said to be the best agm on the market, but proberly not the most economical for the dollars.

Peter ,I run 5 Fullriver AGM - HGL 80amp , no1 as starter in an 80series turbo diesel ,no2 is aux batt in same ,charged through Rotronics w/ender 10------ batts 3/4/5 are on c/trailer in para via anderson plug from batt no2 ,, all 5 batts were bought in 2002 so now 3 /4 yrs old ,never ever discharged to less than 11.2v ,recharged by altenator , solar and/or gen when camped ,expected batt life 15+ yrs //// lots of misinformation about AGMs as so called spurts try to relate and justify wet cell tech against "new" ,, bit like comparing the sound of an old 78 to to a cd/dvd/mp3.

This feels starnge replying to your own post but I thought it might be useful if I relate where my seacrh for a decent priced AGM battery has taken me. I settled on a Fullriver 90AH DC having worked out that the DC series is a heavier build (thicker plates etc) than the HGL series. A number of solar suppliers are shifting to the DC series. Despite Mainey being in Perth he has helped me source one in Melbourne at a very good price. Thanks mate. Now to pick it up and get it fitted ready for the Cape.
