Iām curiously waiting for you to take the momentous leap and completely remove the auxiliary battery from your vehicle.Just completed two weeks with the Aux battery bypassed. No difference in the operation of the jeep, I actually forgot it was bypassed. Bypassing hasn't changed the running voltage, still running around 14.7 v.
No programmer and I intend to always disable ESS, but the times I forget, it always works as designed.Seems it hit and miss on the voltages running high, some say 14+ all the time and others like me reporting voltages are between 12.6-14 depending on whatās going on, super glad to hear your bypass invention has worked without issues, so do you use a programmer like a Tazer or Flashcal and do you use ESS
I don't have any plans to physically remove it, but with the ground cable disconnected there is no electricity flowing through it, so it is electrically removed. It does provide a benefit when it works, so as long as I can bypass it when it doesn't, it will stay in unless I install a real dual battery system.Iām curiously waiting for you to take the momentous leap and completely remove the auxiliary battery from your vehicle.
Iām interested in making it more simple. Do we really know how long this aux battery will last and what it will cost for replacement? As everyone knows a standard automotive battery lasts at least 5 years with a simple replacement procedure. From what Iāve seen from other auto manufacturers, aux batteries only last about 2 years, canāt be easily purchased only through dealers and are very expensive.I don't have any plans to physically remove it, but with the ground cable disconnected there is no electricity flowing through it, so it is electrically removed.

You don't have to rely on the experience of other auto manufacturers, FCA already had this system in place on other vehicles, check out some of those forums. I looked up the PCR part number (56029766AC) and then referenced which vehicles used the part. I got the most information on a Pacifica forum. Let's just say I don't have much hope things will improve.Iām interested in making it more simple. Do we really know how long this aux battery will last and what it will cost for replacement?

Don't wait until it goes bad to bypass it, if you're going to do it, bypass it while it is still good. Then if your main battery is not able crank the starter, you have a functional backup available.@Jebiruph Iām thinking when my ESS battery takes a crap outside of warranty Iām thinking just bypass it as you have with the bypass cable kit you invented and just use the main battery
I will suggest that the ESS battery issues probably haven't been as big of an issue on the other vehicles as they are on the Wrangler because the other vehicles are less likely to get stranded out in the middle of nowhere.You don't have to rely on the experience of other auto manufacturers, FCA already had this system in place on other vehicles, check out some of those forums.

According to my notes, somebody posted a battery part number of BBAUA200AD, which I see priced around $120. As far as battery life, everything I have read is anecdotal, so no set time for how long it lasts. But based on posts in related forums, other vehicles seem to have similar failures. You would have to read them for yourself and make your own conclusion.To enlighten us all with this knowledge, do you know how long the aux battery lasts and what is its replacement cost?
Well if your wondering if the aux battery fails will you still be able to drive your JL you need to catchup on the battery bypass invention that @Jebiruph created, he ran with this bypass on for several weeks I believe and the ESS battery was disconnected and I donāt believe he had any issues.Iām wondering/hoping that the ESS hood switch deactivation will allow a maximum lifespan for this aux battery. Also if this battery does fail will you still be able to start and drive the Jeep?
