If it's cranking over longer before it starts, the fuel pump is probably leaking down as it sits. Try turning the key to ON a few times without stating it.Battery Voltage-Circuit Voltage Below Threshold: Parktronics Module: B2199-16: Body: Current: Battery Voltage-Circuit Voltage Below Threshold: Radio Frequency Hub: B2199-16: Body: Confirmed: Battery Voltage-Circuit Voltage Below Threshold: Radio Frequency Hub: B1A10-00: Body: Confirmed: RKE fob 1 Battery Low: Radio Frequency Hub: B21DD-84: Body ...

It’s very possible, there are several things that keep ESS from engaging and battery charging is one of them as I believe the JL is programmed to monitor that voltage of the ESS battery and if it’s low it won’t allow ESS engage, it’s actually a very over engineered system, it’s best to have both batteries load testedWith just 1 or 2 exceptions through the years, every such battery that I've had in service has provided no less than 6 years of practical service. E.g., as I type this post, the original battery in my 2015 Suzuki continues to reliably crank the engine, 8 years running. The Jeep's [original] main battery does the same, 3+ years on.

It's called "regenerative braking". Your JL has it. When coasting and foot off the pedal, the generator charges the 48V battery. This applies to vehicles with eTorque. My jeep does not have eTorque. OK, then something isn't quite right. When my JL is cruising (with eTorque) my voltage shows 14.2 as should.Anyone that has the voltage stay at 14+ all the time should have batteries checked, when I had my original setup all was well for the first couple years then the voltage just kept creeping up and stayed over 14+ most of the time and I would occasionally see 13.8 on a long drive, even after putting the batteries on a Deltran and letting it sit for a …You will see 14.x volts, sometimes 13.x volts, I've noticed on long trips when the battery clearly had more than enough time to hit fully charged, it might even drop to the battery float voltage 12.7-12.8 volts, …Battery Voltage-Circuit Voltage Below Threshold: Parktronics Module: B2199-16: Body: Current: Battery Voltage-Circuit Voltage Below Threshold: Radio Frequency Hub: B2199-16: Body: Confirmed: Battery Voltage-Circuit Voltage Below Threshold: Radio Frequency Hub: B1A10-00: Body: Confirmed: RKE fob 1 Battery Low: Radio Frequency Hub: B21DD-84: Body ...The easy and simple answer, battery charging in controlled by the PCM and running voltage is based on battery temperature. Higher battery temps, lower voltage. Lower temps, higher voltage. In the 90's and 00's, that was true and a change in the charging systems to prevent overcharging the battery.

Not sure if this helps but genesis offroad makes a dual battery kit for the JL. ... 2018' Jeep Wrangler Unlimited Sport ... Smart alternators won't generate sufficient charge voltage under normal conditions. Battery capacity is reserved and charge is dumped to the battery during braking under alternator control.I actually never really gave any thought into having the ESS system disabled via the Tazer and it having an effect on how it charges the batteries, like I have stated in past posts on my battery voltage, it’s been reading 14+ volts for several months and used to run 12.7-13.9 depending if I was driving steady or accelerating or decelerating but now it’s a constant 14.2 +/- .2 This reading is your current battery's voltage life. The reading should be around 12.6V with the vehicle and all accessories off. If it is lower, the battery might need to be replaced. A standard battery voltage rate compared to charge percentage would be follows: 12.60 volts = 100% charge; 12.35 volts = 75% charge; 12.10 volts = 50% charge The OEM auxiliary battery was 200 CCA size group 12. The only new 200 CCA auxiliary battery I could find was a group size 14, which will not fit down into the auxiliary battery well. Not even Jeep sells the 200 CCA group 12 battery as of this time. Jeep only sells a 180 CCA size 12 battery.A week ago, we saw Stellantis (FCA US, LLC) issue a recall for a risk of a battery pack fire for the 2021 to 2023 Jeep® Wrangler Unlimited 4xe (JL) plug-in hybrid (PHEV).

After being repeatedly shocked at hearing so many here referring to having to change their batteries out after just three or four years, one member pointed out that the JLs are set up to NOT charge the battery at the maximum possible voltage, but that the battery charging is limited to 12 volts, apparently in the (absurd) name of "fuel economy" ...When driving, check your battery voltage on the instrument panel: ...

When the warning light comes on, the alternator is most likely not working properly. A faulty belt in your Jeep Wrangler could also be a cause.

In the JL it can clearly go to intermediate voltages between 13.8V and 14.4V, which is much more preferable in terms of limiting over charging and protecting the battery health. I don't know for certain if the charge controller in the JL is sophisticated enough keep track of the charge history of the battery to know when the last time the battery was …I was able to confirm that the Aux battery is dead. Using a voltmeter with a very rudimentary load tester, the Aux battery voltage measured at 12 but dropped almost instantly to 2 with the load applied. It is still under warranty, so it will go to the Jeep dealer when I get home.The "Battery" voltage is just a faux description, it's really the vehicle's charging system's overall output 'effort'. Regardless, the voltage shown indicates essentially 'how hard' your alternator is working to charge your batteries, not necessarily the battery's true voltage. The unit of measure can be anything.44 posts · Joined 2014. #1 · Jan 5, 2022. I have a 2018 JLUR 2.0L that for a few weeks now has needed to be jumped to be started every time I go to start it.

The first suspect in the Jeep JL’s charging system is usually the alternator. A malfunctioning alternator might not provide enough power to keep the auxiliary battery charged, which can cause a slow but consistent battery drain. If the alternator checks out fine, the next element to scrutinize would be the voltage regulator.
