Not tried an AGM but my Yuasa failed due to lack of charge but they have a 5 year guarantee. Luckily I found my Halfords receipt (2 years old) and took it back. They changed it with no quibble at all after testing it.. I Have an HSB010 which is a bit bigger than standard (as advised on here) sits just over the tray but seats OK. About £120.
Not understanding this obsession with bigger batteries and higher CCA ratings. Obviously supercharged cars might require more.
I get these engines are big, but they aren't diesels and turn over easily with a (decent) correct fit type 027 battery.
No need to bend the tray, or modify anything and it is secured properly as intended.
I think batteries fail early due to lack of regular use, many Monaro being 2nd or even 3rd cars rather than a daily.
As for AGM batteries I've no experience at all.

I've got an AGM battery in the back of my Monaro, Odyssey PC-1230, got it when I relocated the battery, as it was going to be in the boot I wanted something a little meatier as I'd heard stories of them being harder to start with the battery relocated. The positive cable running to the front of the car is pretty chunky too 
For me, it cranked the engine over better than when the battery was in the front, so I was happy. It also lasted well in terms of being left for long periods and surviving. During a period of depression the car sat untouched for over 18 months and that was enough to eventually kill it off (wouldn't hold a decent charge any more) so I replaced it.

my tracker plus the upgrade from the standard monaro alarm drains the battery quicker same as my fsti (Forester sti ) , the bigger capacity means it can sit around longer with out issues , i accept sitting around is not great , i also agree you don’t need a larger battery to start it , but as above bigger battery lasts longer

My 027 Yuasa died after almost exactly 2 years. Unfortunately I don’t have the receipt and cannot take it back. It spends a lot of time with a battery tender attached and I think that’s what killed it.Weird thing is it still shows 12.6v although when I turnEd the key, after a run at the weekend, it wouldn’t turn over. Alternator shows 13.7 volts at idle with all the pumps running so don’t suspect the alternator and it went first flick on jump leads so not the starter.
Bigger 096 battery won’t fit as I have an engine brace in the way. Besides, Yuasa is 640CCA which is just about enough.
I’ve bought a battery condition checker just to be sure, I’m guessing AGM batteries don’t like the heat ?
Apparently AGM batteries don't like extremes of temperature no, so an engine bay may not be an ideal location, although not sure on the actual temperature range...
Mine has been in the spare wheel well effectively sat nicely above the exhausts so has presumably had a relatively warm time of it, but never had an issue starting.
I use a CTEK MX5.0 as a battery tender, has an AGM specific mode (as they're more sensitive to over voltage I believe) and also recondition cycles etc. Friend whose dad has a dealership has used CTEK stuff for years with no problems.

Anyone fitted one to a Monaro? I know they are a bit temperamental but my (Yuasa) battery has died again so trying to work out what to do next. Certainly the extra CCA will come in handy.
Is your charging system designed to run AGM ?And what problems are you having that you need extra CCA ?
How old is the current battery, and why has it died ? Has it been allowed to run flat ?
Have you tried a reconditioning type charger ( even the little C-Tek's offer this ) ?
The battery is 2 years old.
Tester says it’s “good” but low charge - 12.4 volts/73%
Cranking test turns up as “low” at only 9 volts and 470 cranking amps against a 640A CCA battery.
When it was hot, it wouldn’t even turn over the starter. So I think the battery is sulphated, I’ll try to recover it using my CTEK 10 amp jobbie but a bit more oomph would be welcome.
AGM batteries can be used on our cars but not sure how long one will last.

Mine is just some "cheap" 093 I think it is, Inci or something, made in Turkey I believe. Easily 10 years old and still works great.Tester says it’s “good” but low charge - 12.4 volts/73%

Although as the vehicle does sit for too many extended periods I always disconnect the battery. No battery likes being run flat, and it can cause them harm
And if and when needed ( not that often really ) I'll slap a little C-Tek onto it.
ie...this sort of thing, just what the local sells, or did at the time anyway.

I've never had a starting issue, LS's start very easily anyway.
I don't buy into all this fancy or lightweight battery crap. I want a battery that will run anything I want, when I want !
The last big yellow Optima never lasted as good as this one.
I’ve had a little Oxford 900ma charger maintaining it for the past two years. It’s designed for motorcycle batteries and I think I may have knackered it! My big CTEK gives it the thumbs up and I’ve put it into recondition mode which mixes up the acid which sinks to the bottom over time. I’ve also bought some decent, replacement battery terminals as the earth on the negative battery post is not as tight as I’d like and won’t tighten further. That cannot be helping.
Yes they start easily but they don’t spin over quickly!

Mine cranks at 145rpm or so, which is fairly reasonable. Same starter I've been using since I first went LS back in 2004 or so.Yes they start easily but they don’t spin over quickly!
My little C-Tek brought the battery back to life on a van I bought a few years ago. It did seem pretty dead, wouldnt really last anymore than a couple of days without driving.
But after doing the recon with the ctek, almost 4 years on the same battery is still in the van and working quite fine.
Well...3 weeks parked up would maybe be its limit now, but that's not terrible all things considered.
But I'd just slap it on a charge every 3-4 weeks if I'm not using it.
