Trickle charging for 2.0L with 48V battery

[Rhinebeck01]

@ViperJon

Never had any problems using the quick disconnect cable, on any of the JK's I have had over the years.. (a few)

I have had the quick disconnect on the JL for many months now, and no issues.

Hmmm, not sure why you had issues.

On the JL, I have connected the quick disconnect cable to #4 and #7 on the Main battery (see pic)

Using a 1.25 amp, Deltran Battery Tender Plus, on my 3.6L JL, it can take anywhere from 12 hrs.+- til the Battery Tender indicator goes green.

No way, in 6 hrs. are you going to see green.

By the way.... there is the 1.25 amp Deltran Battery Tender Plus and the .75 amp Battery Tender Junior. The Junior will take longer in regard to charging your JL.


Also, I have 3 Battery Tender Pluses. Have used this model for years. I have never seen them go to green in 15 min... and that is on any vehicle.

You should be able to go away for months if you want, and if the Battery Tender is connected, your JL will be aok while you are gone and it will be aok to start right up when you get back.

@Rhinebeck01 and everyone else that responded. Thanks for the feedback. Now that I know it's ok to leave my BT Plus hooked up for a day to the 2.0L with that 48V in the system too, I am trying again now and will report back.

Finally, success!
At 11:50 est the green light is on. Apparently the Deltran Plus battery tender has completed it’s work on JL 2.0 battery EUREKA!

@Rhinebeck01 She's all charged up in only 2 hours! It's a relief for me that I can trickle charge my 2.0L the same as any other vehicle, and don't have to worry about how the 48V battery is interacting with the charging process.

Here's what I think happened. My JL is only 2 weeks old and only saw 1 good highway run on the way home from the dealer. The rest of the trips were short in the city. Plus, I spent some time last weekend sitting in it with the key (button) in "run" (engine not running) while I went through menu selections and a bunch of Sirius setup. So I think the 12V was down a bit, taking my BT Plus longer than normal (for me) to achieve green light charged status. Yesterday I was on a 4+ hour highway trip, fully charging my 12V in the process. Then I hooked the BT up this morning and it only took 2 hours.

Thanks for your feedback everyone.

I have a Harley battery tender I use on my bike. Would that also work on my Moab. I have the tow package and heavy duty battery.

@Al13
Yes, it will work on your JL.

I just posted a question on another thread. If the Jeep will start and the electrics come on with just the small battery connected and the big battery disconnected but will not start if the big battery is connected but the small one is not, what is the purpose or role of the big battery?
In “Jeepinformant’s” Youtube video he shows this scenerio but he doesn’t explain the purpose of the big battery.
Any thoughts?

@marjamr

On the forum, there's lots of info in regard to the 2 batteries on the JL. Suggest you read read... You will have to spend hours to go through all of it.

Pay particular attention to posts by @Jebiruph as he has posted lots and for sure he has a handle so to speak, on this issue.

Of course, @Jebiruph like many of us, is often speculating / guessing / assuming things a bit, in regard to the batteries but he is partucularly attuned to this issue.

Anyway do read..

By the way, don't take all that the Jeepinformant has to say about the batteries or anything at that, for granted... why people take all things he spews for granted, as gospel, puzzles me.

Oh... for the record, my JL will start if I take the Aux battery out of the picture.... Main battery starts the JL and I can use / drive the JL without the Aux and you'd never know the Aux was not being used.
