When you need a long lasting battery that can withstand the tough Australian conditions, deep cycle AGM batteries are a great choice. AGM Batteries use glass mat technology within the battery to absorb the acid, as opposed to standard flooded batteries where the acid is free flowing. This provides several key advantages over standard batteries, such as allowing the batteries to be 100% sealed, non-gassing and maintenance free (batteries will never leak acid, even if damaged), and providing a significantly longer service and cyclic life (up to 2-3x longer than standard batteries).

Deep cycle AGM Batteries are perfect for applications that require either frequent cycling or renewable power storage. Common uses include running appliances when camping away from power, using with a solar panel for charging, running in a dual battery system in a vehicle, or providing safe power on a boat.

  • Can these safely be used in the car cabin without the risk of gasses etc?

  • +3

    And shipping wouldn't be cheap with a 30kg battery

  • Its a pretty sharp price. A good local B&M supplier should be able to match this price but that could take a while to find. This deal means you don't even leave the house! :)

  • REP: in the event warranty is needed, what is your address or where should the battery be sent to?

  • can this be used in a landcruiser 100 series (2007 model petrol0 to replace the normal battery, or is it a bit of a overkill?

    • Can it be used in any car as normal car battery?

    • +3

      you can't use normal AMG battery in the engine bay, It will void the battery warranty. Optima is one of the brand of battery which allow their AGM battery to be in engine bay.

  • I can't seem to find a chart that shows cycle life depending on depth of discharge for this battery. The only info I find is 1650 cycles at 30% discharge. Since it is a deep cycle batter I would want to know the 80% or 90% discharge cycle life.

  • So, these last a long time?

    I take it this battery makes a good second battery for a 4x4? (as in long lasting for the price)

    • +1

      Well, the manufacturer claims a 10-12 year build life here: http://giantpower.com.au/batteries/

      As with all batteries that depends on how often you discharge them and how deep. Have a look at the chart linked by the rep above and decide how deep you discharge it on average and how often.

  • Darn, good price but the battery size is too big. Been eyeing a 60AH one

  • This is a good price for a decent size battery. If I didn't already have a 100AH battery. I'd be all over this.

  • Ordered. Rep how long does it take to ship the product? I'm traveling and don't want to stuck here in Cairns too long.

    • Will dispatch it on Monday.

      • No tracking/shipped email yet?

        • +1

          Hi there,
          Please email me your name to [email protected], I will find out the tracking number for you.
          Regards,
          John

        • That was quick response… tracking No received. Thanks

  • 30kg and free shipping, wow

  • Realistically I think these might go 5 years if they are charged with solar or a smart charger and kept in a case for camping -not under a bonnet. Once you start putting them under bonnet you might get 6 -12 months longer than a wet deep cycle if the conditions are right. Some cars have their batteries in cool locations and you can put agms in. But if the exhaust manifold is on the battery side its certainly not a got idea. I had a gq patrol and it was murder on the agm battery, the dual battery tray is next to the exhaust manifold and id say the charging system is not so refined. I got the same life out of an agm as a deep cycle. Now I have an 80 series the battery only sees a little bit of heat from beside the radiator it seems t be worthwhile to have the agm.

    Be mindful that having that large reserve capacity is addictive so as the battery ages and holds less charge you start looking to replace it pronto.

    You can use these as a cranker no problems but it has to be in a cool location, not getting radiant heat from anything.

  • When we go away camping I use batteries/solar to recharge all of our electronic devices, Ipads, phones, DS etc etc (Autistic son that unfortunately needs these devices to work when we go away).

    I was thinking of getting multiple smaller 22 AH Batteries for when we go away.

    http://batteryfactoryonline.com.au/product/ritar-rt12220ev-f…

    These are $55 for 22ah batteries delivered. And I was thinking of getting three of them, but if I were to stretch to four it would be roughly the same price as buying a single battery as above.

    Is it better to have multiple smaller batteries or just a single bigger one?

    Thoughts on the above setup?
    NB. currently looking for a decent solar charging system, was thinking about a 160 Watt unit, just to future proof our power requirements.

    Thanks

      There are a couple of trains of thought on this.

      1. It is always best to deal with the smallest amount of cells in parallel to avoid balancing and over/undercharging issues as the cells age. Also at this price it has a much higher capacity for less dollars.

      Or

      1. In your situation, it may be easier to carry 3-4 smaller batteries spread across backpacks. Also for redundancy if you have multiple batteries and one or more cells fail in one, you can just remove that battery and still achieve full voltage albeit at a reduced AH rating.
  • I have a surf and the battery would be on the aircleaner side :) the coolish side, still for that price I was hoping it might last for at least 6-7 years or am I better off with a cheap deep cycle?

    • Seems to be a number of people considering these as car starter batteries. Aside from heat issues do they charge correctly/ fully with a normal car regulator designed from a wet cell starter battery?

      My understanding was that AGM's like a higher voltage than wet batteries to obtain 100% SOC?

  • A car's battery is designed to provide a very large amount of current for a short period of time
    A deep cycle battery is designed to provide a steady amount of current over a long period of time.

    AGM (absorbed glass mat) is a special design glass mat designed to wick the battery electrolyte between the battery plates. AGM batteries contain only enough liquid to keep the mat wet with the electrolyte and if the battery is broken no free liquid is available to leak out.

  • Beware that this mob don't honour their purchases.
    Still waiting for the "so-called" included watt meter purchased a month ago 18/10.
