I ran AGM / Optima batteries in my Z0-06 Corvette, but only because the battery tray was directly over a lot of electronics that leaking battery acid would have caused big $$$ problems.
That's is not the case on my 2015 TRD Pro 4Runner. Not meaning to offend anyone here, but why bother spending the extra $$$ on an AGM battery when a Walmart battery would work fine? My OEM battery is still working fine going through pretty extreme heat and humidity in Houston.

I've been looking to either upgrade the existing Panasonic battery with an AGM or to install a second battery. I need more capacity to run my ham radios when parked.
It seems like Autocraft Platinum batteries get very good reviews. A size 24F has 710 CCF and 70 AH capacity which is nice. It lists for $199 but you can purchase it online (pick at your local store) with a 20% off coupon to bring the price to around $160. It's not bad for an AGM battery with a decent capacity. I've had one on my truck for 5 years until I sold the truck. The battery never gave me any problems and I could run the radios for the whole day without having to run the engine to recharge it.

Odyssey 34M-PC1500ST dual post battery
Any thoughts of using this marine battery as has dual posts if want to hook up accessories. I will be adding a winch and LED lights soon. Has the cranking amps and the reserve amps to handle most anything.

I bought the Northstar 31m and it was a waste of money getting the dual post...they are so close together you can't hook up accessories to the second terminal. If I think about it I will get a pic tomorrow showing the issue I ran into related to this.

I like that it has the dual posts, I also like that it's name is Trolling Thunder lol

9 year run on lead is pretty good... you must actually take care of your stuff.
I got away with running a Costco Interstate starter battery as my house battery for years. It still does surprisingly well when you don't need to discharge it to the floor.
The battery takes the fridge load overnight without a problem, I don't even hit the low voltage disconnect which is set at 12.1v To a degree I even question the need for a true deep cycle for most weekend warriors.
I can supplement it with a 50 watt solar panel and you don't even need to start the truck all weekend... I have it, but never use it.
That said, when it time to replace, I am building a custom lithium solution which should be pretty amazing in terms of size/weight and run time.
False. Read your warranty and specs, the factory charging system will void your warranty because the voltage is too low.
Odyssey requires 14.0 to 14.7V, the factory charging system is not sufficient for an AGM battery, the voltage is too low.

A lead battery, AGM or other, will slowly sulfate internally if you can’t provide it with the correct charge voltages. It’s a slow death and you might not notice it is happening at all.
If you actually capacity test your battery, as in run the cell from 100% to 0% state of charge by voltage and measure power out consumed, you would basically see a greater loss of capacity over time vs a unit that was maintained correctly. Both will have capacity loss, but one will be at an expedited rate.
In addition to the capacity loss, it's ability to delivery higher currents will also be reduced.
It will continue to degrade and its ability to hold a charge will reduce. Ultimately forcing you to remove it from service. By that time, its ready to replace and probably too far gone to recover properly. At the end of the day, all you are doing is reducing its potential service life. It just wont last as long as one that was maintained correctly.
Batteries are pretty simple devices... how you treat them is directly related to their service life.

2 years those batteries are still babies.
I would expect a premium AGM to last 5 to 9 years. You won't see these ill effects until later in life.

Actually, Enersys says otherwise. [MENTION=336]03_4x4Runner[/MENTION] talked to them and I have my info from them in writing from last week.
The fine print on everything is normally made to make things look scarier than they are in order to prevent abuse. Write them an email and see what they say for yourself.
What about DieHard AGM?
I have a 4 year old Diehard AGM, fine so far, although I plan to test it before winter sets in hard. Not that winter is all that bad in NJ. No special voltage adjuster installed.
Advance Auto is carrying the DieHards now, since Sears is just about dead.
Does anyone have more experience/info on the Diehard AGM?

Diehard AGM ?
Looks like Johnson Controls makes them.
If they do, it's probably a good battery.

you could give these peeps a call to see if their application will work for you......
