Battery charger, maintainer and propper use

[gladerater23]

I bought the adapters on Amazon. One converts the 7 pin to a 12v outlet like a cigarette lighter outlet, the other plugs into that and has two wires which I connected to the charger via bullet type terminals.

The only thing I worry about is forgetting it's plugged in back there! So I stick a piece of curled cardboard in the door handle as a reminder to walk back there and disconnect.
I did forget the first time - but nothing bad happened as the lighter plug came out of the socket adapter! It simply leaves the power adapter (bottom pic) in the truck, no biggy.
I use the adapter for other stuff anyway, and I needed the male plug for another project so for me it wasn't an expensive setup.

I sometimes go on longer drives or more frequent drives, but still do plug things in fairly frequently. It might be one reason I've had decent luck with batteries over-all.

Awesome info, thank you.

That's totally wrong because the two batteries are connected in parallel at almost all times - even when it's an ESS stop.
Too much bad/incorrect info on that. Disabling ESS will not change how the batteries last or don't last. And the aux won't be a heavy hit on the main anyway - when stopped, the load is on both batteries, not the aux.

Haha, tell that to my volt meter.

Go back and check my tests with TWO volt meters showing them going up and down in lock-step. I've got a thread or two on this showing the meters and cluster dropping at the same time.
Plus - we've discussed this ad nauseum for years here. It's quite simply - how it works. Several things are actually connected directly to the main battery, not the aux - including many accessories if you follow diagrams.

Both the main and auxiliary battery handle the load during an ESS stop.
I have connected meters directly to both batteries, and monitored while driving and pulled into parking lots and watched as both batteries went down at the same time during the stop - pretty closely matching the cluster display.
The separate only during the startup for a brief moment.

It's really a settled thing.

I need a recommendation on the proper battery maintainer and or charger for a 2023 Jeep gladiator. This is my daily driver however it's used in a lot of stop and go traffic therefore I know I'm not doing the battery any justice. Also proper place for connections to ensure both batteries are being charged? Has anybody installed an easy Plug and Play method for quick detach?

I have been using this one for a year and just ordered another one for my Willys.
Works great. Once it stops charging it will maintain your battery.
Last April we where gone for 30 days and when we got back home my wife Rubicon battery was completely dead. That's when I started using this charger.
Most of the time we are in my F250 and the jeeps may sit for weeks drawing down the battery's.

I plug mine in every time I park in the garage. And the outlet can also power 12v accessories when out on the road:

That's originally what I got my adapter for - 12v accessories. Then I later wired all that into the bed and use the rear one for charging.

Neat setup there........

I have a NOCO Genius 2D plugged into both my 21 JTRD and my 23 JTM. After four years on my batteries on the 21, I just changed the batteries as I didn’t want to find out the hard way that they were dead. My ESS works every time on both trucks but I usually shut it off. The other reason I changed the batteries in the 21 was I started getting the “Battery Charging” message on the ESS screen. So I do like having that system to measure my battery health.

I just bought tenders at Amazon with the rings to hook them to the main battery. I Velcroed them to the top of the battery and ran the cable down the wheel well behind the fender liner. Two zip ties and I just reach into the wheel well to plug them in. They really work well and it is not a big deal to plug them in.

Another vote for the NOCO Genius 2. It's "smart" so I plug it in when it sits for a couple of days and just leave it plugged in. It MAINTAINS and it has worked very well for that.

So the circuit remains 'live' from the trailer plugs when the vehicle is off?

That's why I went with the BatteryMinder - it charges where necessary, then simply maintains and you can leave it on all winter like I do my cars and lawn tractor. It is also small, plugs directly into an outlet. I had one from before my first Gladiator and just kept going with that brand, but NOCO 2 would be another choice if I wasn't already there with what I have (and all of the accessories interchange)



Frankly, the NOCO, BatteryMinder, or anything that operates in a similar fashion will work - they top off the battery as needed then keep watch over the battery - especially for self-discharge and for parasitic drains like our Jeeps have, and maintain the battery for us.
That's what people need to watch for - something that will charge (slowly, if needed) and maintain, and can be left connected for hours, days or weeks without battery damage.
The NOCO and others are also good for AGM or standard batteries.

Yes, on Gladiator. It's live 24/7.

Doesn't seem to be live on a JLU 4xe, however. I'm unsure as to why, but tried it with my wife's 4xe and got nothing. But it was really cold out and I didn't really check - maybe I didn't get a good connection so will check again.

The reason I chose this one is because my jeep may sit for several day or even a week before I hook up the charger.
It will charge at first 15 to 18 amps and ramp down to maintenance charge.
If I had chosen a 2 amp charger it would take days to bring it back up to full charge.

Parasitic drainage is the real deal. I have never had a vehicle so juice hungry just sitting. I am sure my Tazer compounds the issue.

All of those tiny milliamps add up over time.
Totally agree, it's gotten really bad over the years. Supposedly even the RSE power steps have a certain amount of draw at all times. I can't figure out why they deemed that necessary, but with everything going on with these - plus the fact we up to this point haven't exactly gotten top battery technology from Jeep (everyone complains about modern batteries)................

Could be the tazer.
I have never ran an amperage draw test put I wouldn't be supersized if its around 1 amp.
