Battery thoughts

You weren't joking about lead-acid batteries being non-jumpable?? Dude - people jump start cars all the time....:der:
 
WTF are you talking about? LOL :der:

If you drain your conventional lead acid battery in the middle of nowhere u r screwed. I’ll take any agm battery any day of the week for peace of mind, at least it’s jumpable when u need to.
 
I’m as confused as you are. :shrug: not seeing the forest through the trees or well even any trees. I guess, I too need a better explanation.

From my experience if u keep draining a lead acid battery there is a point where it won’t retain a charge. Sure you can keep jumping it but There is a point where the battery needs to be replaced.

Agm batteries are way more forgiving in this regard.

To misses Jenkins: believe what u want to believe.

Ahhhh, okay, yes that is true. But it will survive and be recoverable (not fully) at least a hundred cycles or more (obviously less depending on its age) more than I think the average Joe/Joanie would do.

I would say that your post made it sound like a single event would cause catastrophic failure. Sometimes I miss the clarity.

Ah yes. When you can't express yourself coherently and your self confidence is so low.you can't take people misunderstanding you or asking for clarification run on home to grammar school playground insults. And here I thought you'd made a sophisticated and quite dry joke and complimented you for it! LOL.:der:
 
I run the basic lead-acid one, and carry a portable jumper. I do not see the cost of the other batteries worth it unless you have a special need.
 
Can you provide more details on this and why?

The odyssey warranty says:
Alternators that do not have a regulated charge between 14.0V and 14.7V (no lower than 14.0V and no higher than 14.7V) will cause early failure of the Battery. Use of such alternators with the Battery will also void the Battery’s warranty.

The 4runner doesnt have regulated charge between 14.0V and 14.7V, you need a voltage booster (which are inexpensive and take about 30 seconds to install)


All that being said, unless someone has a specific need for an AGM battery just stick with normal lead acid
 
From the Oddysey warranty:

"For applications where an alternator is present, the alternator must deliver between 14.0V and 14.7V when measured at the Battery’s
terminals. Consult the ODYSSEY battery technical manual or owner’s manual for any necessary temperature compensation.
Alternators that do not have a regulated charge between 14.0V and 14.7V (no lower than 14.0V and no higher than 14.7V) will cause
early failure of the Battery. Use of such alternators with the Battery will also void the Battery’s warranty."

Toyota specs for the stock alternator is 13.2V to 14.8V. They typically run right around 13.8V which is the industry standard.

Maybe they don't really care but if what you're buying is a warranty then you might think twice. Personally when I buy a battery I'm looking to buy a battery, not a warranty so I just buy a good quality conventional battery and don't worry about it. Only battery I've ever had fail prematurely in over 30 years of driving was an Optima AGM.

I am not going to fight this battle again. It has been done enough in the past. I will continue to run my Odyssey battery and you run what you want. I never use conventional batteries in anything anymore because once they start to fail they start leaking acid at the post and corrode them. As I stated I talked to Odyssey about this application and they said it is fine.
 
Even hard off roading wouldn't warrant a agm battery unless you were going remote for a few days and would need a deep cycle.

i use agms on my boat cuz they are maintenance free sealed that wont spill acid as they can be mounted upside down if need be and vibration resistant.

regular lead acid for the win.. and save some coin for mods

That's great they gave you a verbal assurance and if you trust them to back it up that's great. I wonder why they don't put it in writing?

All this lead acid, AGM deep cycle, Lithium battery stuff. I've been on the Flux Capacitor since 1985 and never looked back.........

I had to upgrade mine to the flux capacitor that was powered by compost since I live in kaliforniastan.

I could only travel to 1999.... juice not with the squeeze
 
This is a timely thread for me... went to start the 4Runner yesterday and it didn't have enough juice to turn the starter unless I switched the headlights off. Hooked my charger up to the Interstate MT-24F that's in there, and it gives an error which indicates the battery wont even take a charge. Would've liked for it to have lasted longer, but I guess I can't complain being that its nearly 4 years old (the kids also left the interior lights on once or twice and completely discharged it).

Wife is making a Costco run this morning anyway, so I bagged it up for her to just grab a new one there. I don't think you can beat $90, given the return policy! The current battery was still under the Interstate "performance warranty" which would get me 10% off, but that still isn't enough to make it the same price as a Costco Interstate.
