FYI Costco's battery finder system will not show an Interstate brand battery for the Odyssey because the 24F was not a flush cap but raised. Is this why you went with the AGM?
To be honest, I was never going to buy the Kirkland flooded battery so I didn't really pay any attention to it. For me, it was a decision between either the Energizer AGM from Costco or an Interstate MTP-24F at a local auto parts store not far from my home, both of which were going to fit just fine. Now you've got me curious what I would have found had I really wanted the Kirkland battery.

The Costco guy told me they didn't have a battery for the Odyssey (Ours is 2005) at first then I pointed to about 7 group 24F's they had on the shelf. I'm still undecided on AGM. For the Odyssey I went with the Interstate (flooded) at Costco because it's dirt cheap for a solid battery. But in my Mazda 3 I went with an AGM (Champion) replacement because of a PepBoys $50 black Friday rebate. Only time will tell if the AGM is legit.
I agree with you there - time will tell whether the AGM battery is worth the extra expense. I'm hopeful that it will handle the engine-off demands of the power sliding doors and the power front seats better than the factory battery (I'm six inches taller than my wife so the seats are moved quite a bit every time we switch drivers).

Pep Boys has been selling Champion and Bosch-branded AGM batteries at a discount for some time, but the retail price has gone up by $10 to $199.99. They both have a four year free-replacement warranties, which is longer than other brands of AGM's usually offer. Then, they have been giving 25% off of any size battery every month, bringing the cost to $149.99 plus tax. Then, they offer a $40 Pep Boys reward card on top of that, so the battery costs $110. I do not like rewards cards but I have learned I can pay some of my bills by phone using these rewards cards.

I use two AGM H-8's in parallel for my computer's 24 volt battery backup system, and hopefully I can get 8-10 years from them. They will power my TV and computer all day and more. I put one AGM in my Odyssey and another in my neighbor's Freestyle. I seldom got more than three years (in Florida) from the flooded Costco and Sam's Club batteries I have purchased. My Odyssey OEM battery lasted 3-1/2 years. These flooded batteries fail shortly before or rght after the warranty expires. AGM or no, the price per year of warranty is about the same or less with AGM compared with these flooded batteries. My neighbor got about 9 years from the yellow Optima battery in his truck.

The operating characteristics are slightly different for AGM batteries. My concern is that we now have electronic monitoring of battery condition in the newer vehicles. This is done differently by different manufacturers. So far, I have no issues with the AGM battery in my 2016 Odyssey. My 2017 VW (still on the OEM battery) should have the ECU re-programmed after a battery change, and supposedly requires a VW-approved and numbered battery.

Whatever battery you have, do not run it dead, which will kill flooded batteries very quickly. AGM batteries supposedly hold up better under very deep or complete discharge conditions.

Time will tell if AGM is the way to go.

The Costco flooded batteries aren't Kirkland, they are Interstate. As others have said, I didn't even see AGM's at my Costco. Only the Interstate flooded.

Black Friday I bought a Group 35 Champion AGM from PepBoys for $140 and then sent in for a $50 Visa rebate. $90 not too shabby for an AGM.

It's very possible all 3 of them are the same exact battery with a different sticker.
This is most likely true. If the "Energizer" AGM batteries sold in Canadian Costco stores are made by Clarios, then the "Kirkland" flooded ones probably are too. And if American Costcos only have Interstate batteries, that's one of Clarios' brands as well so the batteries are probably all the same.
