Yes.

Maybe people use the term "trickle charger" in a generalized sense, but use a 12V battery charger with an AGM profile.

Regular maintenance charging is the best way to maximize the life of an AGM battery since an alternator effectively only ever "sufficiently" "replenishes" the battery as opposed to properly charging it with bulk, absorption, and float phases.
No.

While I agree with you Foster that the charger need be compatible with AGM chemistry batteries, a "trickle charger" and "battery charger" are two distinct things, and Tony is best suited for a trickle charger.

e.g. or one with higher amperage https://www.amazon.com/NOCO-GENIUS2...o+2+amp+trickle+charger&qid=1706827749&sr=8-5

Tony: you seek a device that you can put on your batteries to compensate for their loss of power over time due to the natural loss of power due to Entropy as a product of their lack of use. A well designed trickle charger can be left on the batteries indefinitely and will not cause harm.

A battery charger is something you'd use to charge dead or near dead batteries.

Running with one battery and no ESS system engaged, unless you very infrequently use your vehicle or subject it to unusually cold temperatures you may very well not need a trickle charger at all.

I disagree.

AGM batteries are not particularly vulnerable to self-discharge. If a vehicle will sit for a long period of time, disconnect the cables from the main battery negative terminal.

In every case, regularly maintenance charge your AGM battery with a proper charger to prolong its life. A "trickle" charger offers no practical advantage over a modern AGM charger which can be left on the battery indefinitely and will properly maintain it long term.

the charger i will use will be a batteryminder 2000 series it is a charger/maintainer/desulfator with a temperature compensation it will work with the agm battery's. Should i still pull fuse and disconnect negative cable

Please provide a link.

pulling the fuse and disconnecting the cable is a personal decision for those committed to not running the ESS system.

the pros and cons have been discussed above.

I think the cons of keeping the ESS battery are somewhat reduced by trickle charging just as sure as the pros of keeping it are also reduced for those not seeking to run the ESS system, but you seek a yes or no answer to an opinion question.

I have no definites for you. I don’t think anyone does or should.

Andy not sure about a link but if you google batteryminder model2012agm it will come up. Also I only drive my jeep like 3000 miles a year just sold a 2006rubi lj with 26000 miles on her. I guess I might not pull fuse or cable and leave cable on it and just hit the ess switch when i use her

This product is what you need. It is not a battery charger in the jump starter high amps way a tow truck will get you going when your battery is dead, but that might cause sulfation if kept attached too long.

this is a maintainer to trickle charge for you what your battery needs due to natural losses with time and lack of use, with technology to not only not sulfanate your batteries, but apparently, its ad copy is legit, desulfanate them need be.

it can be attached, left on, and forgotten about without inflicting harm.

it isn’t for jump starting you, but rather, hopefully preventing you from ever needing a jump start due to your reported infrequent vehicle use.

thanks Andy and everyone else with this issue I wish jeep would make things easy but what can we do we all love our jeeps, thanks again to everyone! Will keep everything it stock form and use that charger.

A battery booster for jump starts is not the same thing as a battery charger.

Any decent modern charger with an AGM profile can be left on indefinitely for battery maintenance. They have the added advantage of being able to provide higher current to efficiently and properly charge a battery when detected conditions warrant (which is pretty much all the time for auto batteries, since an alternator doesn't provide a proper charge).

Foster, the purpose of my link was to have you hear, from some source other than me , why what Tony needed is better classified as a trickle over battery charger. A maintainer if you prefer.

sure, between the terms battery maintainer, trickle charger, charger and jump starter best of intentions can be lost in vernacular.


your link, best that I can see, explains why, in so many words, charging dissimilar size AGM batteries in parallel, is suboptimal.​
ok​

And more to point, a battery charger is often not a trickle charger or maintainer, which is what tony needs.

battery charger tends to more be associated with that thing you connect when you forgot last night to turn the interior dome light off

Foster, decent trickle chargers also regulate their charge as you describe.

Do you disagree with Tony’s purchase or simply how it’s being described by me?

It sounds like, as usual, we agree more than we disagree.

But, I believe you are missing my point that nearly all modern AGM chargers have a "trickle" function, which renders a trickle charger unnecessarily specialized (i.e. incapable of optimal bulk charging current for a 50+ Ah battery regularly managed by a smart alternator). In fact, a modern AGM charger will immediately begin it's float ("maintenance and monitor") stage if the battery passes initial tests.

I have no problem with Tony's selection, especially if he already owns it. It would not be my choice.

Actually, the link ostensibly explains that emphasis on battery capacity differential is misplaced in the context of discussion of JL ESS battery system flaws, since ESS events introduce different states of charge (i.e. the disconnected batteries power different loads).

I included your link merely to give context to the use of the AI tool (the thought my intention wouldn't be readily apparent did cross my mind).

Let me see if in plain English I'm following you.

Prior in this thread you wrote about the JLs ESS system:

The more I consider it, the more I think the current design is actually quite good for it's intended purpose.
And I'll assume by "intended purpose" you meant essentially "the management of ESS events, all things considered," not my tongue-in-cheek "intended purpose" of passing a poorly designed EPA test and keeping buyer purchase cost of a JL--an already expensive proposition--not even more expensive in bigger and more complex battery designs that consume more of the very fossil fuels ESS seeks to preserve.

Then you reference thoughts on how--if I've got this right--difference in the state charge between two AGM batteries about to be brought into parallel, just like those batteries of many JLs after an ESS event, more than those batteries' diffferent capacities, is the more critical factor.

Ok. So wouldn't that suggest running ESS events with all batteries, different from the Stellantis design that you like, so they can discharge together, be better for the batteries?

Here's my take:

Being able to crank at 3AM on a cold winter night, at a long traffic light, with a so so main battery and perhaps too many aftermarket appliances running, all on a bunch of batteries that today have such poor builds and obsolence that they should be swapped no less frequently than every 3 years, earns greater importance than adhence to the best battery practices (of running all batteries down in an ESS event to minimize charge differences between them as you cite important) that might grant you a few months more battery longevity at the risk of stranding you in an ESS event at a traffic light.

To rephrase: I believe that isolating the batteries, and preserving the main so the post ESS crank suceeds must trump the costs you cite of perhaps alternatively running them down in equal amounts in an ESS event to preserve their life, that early terminates too late to recrank the engine, and is the lessor of two evils. My desire for equal size batteries that swap roles of being main and Aux was merely too even out wear, not minimize wear at the cost of a reliable post ESS event crank.

If your point was to show the limitations of A.I. I agree. I don't post a link (mine) I don't first read and agree with.

Could we give this a rest?
