Can anyone recommend a hybrid AGM battery, something with 700 to 750cca cold cranking capacity and some deep cycle capacity. Want something that hopefully isn't any heavier than 30KG..

Any AGM has very good Deep Cycle capability, some are designed to also provide high starting current.
I have the Remco which is rated for high current, but the tiny connections on it make we wonder how practical it is for starting.
Fullriver seem to be the cheapest AGMs that also have the standard size posts you see on starting batteries.

Nope, they may be good but not the "best..." if we are talking efficiency as a Deep Cycle battery, I actually sell fullriver batteries, however installed another brand of DC battery last week in my own vehicle!!
I now use one of my previous Delkor 80 a/h Deep Cycle batteries as my Cranking battery and gave the other away.
The fullriver battery is cheaper, that said it IS a good battery, just not the best battery :-)

TerraFirma ,what vehicle do you want the AGM for ? I use a Fullriver AGM HGL 80amp as a starter in my 80series turbo diesel ,never misses a beat , the HGL is the hybrid in the Fullriver range ,the 80amp weighs 28kg from memory , does NOT have "normal" large connection posts but uses stainless screw in bolts 8mm.

The application is a boat thats just had a new Outboard Engine installed and requires around 700 to 750 cca cold cranking. 80AH or better would be great. The terminals shouldn't be an issue.. Is the HGL the hyrbid range as I couldn't find any CCA specs on the Fullriver site or link and hence my question and post here. I just need to make sure I meet the required CCA spec for the engine.

TerraFirma ,yes the HGL is the hybrid ,and the 80amp starts a 4.2 diesel so unless your new outboard is one huge mother it should be ok ,, as an aside I use a tiny 4amp AGM to start the motor and run the nav lights/ sonder on our tinny ,only a 10hp but kicks into life first push of the starter every time.

The Exide orbital that I use is a excellant dual mode choice because of its cylindrical cell construction (sorta like a cheap optima).
750cca and 48ah @ 20kg standard N70 size.
Because its AGM it delivers 2-3 times the energy of larger 70 AH standard batteries.
Can by bigger , but its quite enough to run my winch fridge etc so got
standard size to replace normal Patrol battery with ease - also has 2 lots of terminals.

If its rated at 48ah how can it deliver more energy than a battery thats rated at 70ah ( humour me )

Hi Glenn
Its just the depth of discharge thing - in my post I was comparing to normal patrol N70 size batteries.
All AGM's can be discharged a lot further without damage, typical normal 20% discharge of N70 gives only a real 14ah capacity - whereas typical 50% of a 48ah agm gives 24ah.
The exide orbital cylindrical construction AGM batteries, are specifically designed for starting applications as
well, with very low internal resistance effectivily meaning the have less losses and charge up quicker than even your normal AGM of same size.
hence 2-3 times the real power delivered into a starter or winch.

Batteries can be designed to give lots of current for a short period or a small amount of current for a long period, or any compromise in between.
"750cca and 48ah"
- the CCA Cold Cranking Amps shows how much current it can provide for a short period - actually 30 seconds.
- the Ah AmpHours shows how much current it can provide over a long period - actually 20 hours.
So if you're interested in engine starting or winching, then this 48Ah battery may be able to deliver more energy than a 70Ah battery - depending on its CCA ability.

The new range of AGM's from Supercharge batteries are very good and the price works for me too.
The 90 A/H in the N70 case with proper terminals comes in around $220.00 the CCA is close to 900.
