Trickle Charger?

[AndySpill]

@LARSONEM Eric, curious, do you have dual AGM factory batteries in your JL or was yours one that was equipped with only one factory 12V AGM battery...

...or was your JL a dual one from the factory where you bypassed the Aux battery?

I'd opt for the slightly more expensive NOCO 10 over the 5. It'll handle "trickle" charging, but it'll do a better job charging the battery if its state of charge ever gets low for whatever reason.

In the era of smart chargers, the only real justification for buying a dedicated "trickle" charger as your first/only charger is saving a a little money/space.

Both of my JL Wranglers are a single factory battery, no AGM and both are the ETorque models. The charger isn''t tied to that big battery under the back of the Jeep.

My dual battery setup with the charger is on my 2019 GMC Denali HD diesel engine that comes standard from the factory with dual batteries which are still the OEM batteries that are not AGM.

@LARSONEM
i was under the understanding that all OEM 12 volt batteries were AGM. Have you replaced yours with something else?

I have a NOCO Genius 1 hanging from the retractable extension cord in the ceiling of the garage:

It makes it easy to hook up to either Jeep if one is going to be parked for a while.

I’ve been very happy with NOCO’s products

Both of my Jeeps still have the OEM batteries in them; whatever they are. I’ve never really looked at them as they have that carpet blanket over them.

AGM then, I only ask because for optimal charging the charger should be compatible with, and set to the AGM setting.

There is no switch or settings on the 1.25 amp charger. It’s a pretty basic and automatic unit to use

Per the Battery Tender website for product specifications on the 1.25 amp unit:

The Battery Tender® Plus is perfect for all lead-acid, flooded, or sealed maintenance-free batteries (AGM and gel cell).

It also says:

EXTEND BATTERY LIFE

Compatible with all 12V lead-acid, flooded, AGM, and gel cell batteries. Complete 4-step charging program (Initialization, Bulk Charge, Float Mode) allows for optimization of battery power, without overcharging. Smarter than a trickle charger.

BATTERY COMPATIBILITY

AGM, GEL, Standard (Sealed or Flooded Lead Acid)

Like I said, at 1.25 amps it’s not fast but it does the job. I used it first on my dual battery 2003 Silverado diesel, then on my dual battery 2019 GMC Denali HD diesel. I’ve used those vehicles primarily for camper hauling. We store the truck from late October to mid May each year and the 1.25 amp unit has kept the batteries charged on both vehicles.

Thanks all for the suggestions! The Noco5 arrived from @Terrymo yesterday and I got it all setup this morning and ran the cord awkwardly to the garage.

Doesn't look pretty but it'll get the job done for now.

Now you just have to remember to unhook it if you have to move the Jeep. I try to run the cable over my driver side mirror or through the door handle so I remember to disconnect it.

Ha well the "good" news on that front is this Jeep ain't goin' nowhere without a new front axle so it shouldn't be an issue.

To keep the IBS calibrated, the negative clamp should be on top of the IBS.

Like here on the post? Or is it better to not have it on the battery and all and run it to a ground on the frame somewhere?

Yes, on that post will work.
