Lol. Here we go again!!

@jakerc37, only the Grand Cherokees have an aux battery. So on our Cherokees the one and only battery under the hood handles the stop/start system.
 
Man, you guys are bad...LOL!!!🫤😉😁
They are, and I thought I was a smart ass. :LOL:

Since I've had a couple adult beverages and I wanted to show how AI systems are just next word predictors and for now at least, very unreliable..... I decided to check Googles AI (Gemini) search engine response (Called AI Overview) to this aux battery question and I got two different responses. Check them out...

Q: Is there a separate battery for stop start on a cherokee?

A: No, a Jeep Cherokee does not have a separate battery specifically for the stop-start function; the standard battery is used for both starting the engine and powering the stop-start system, unlike some Grand Cherokee models which may have a separate auxiliary battery for stop-start functionality.


Hooray! It got it right! Even the Grand Cherokee part. But if I add just the word 'system' to it....


Q: Is there a separate battery for stop start system on a cherokee?

A: Yes, a Jeep Cherokee with a stop-start system typically has a separate, auxiliary battery dedicated to powering the start-stop functionality, meaning it does not solely rely on the main car battery for this feature; this auxiliary battery is often smaller and specifically designed for frequent start-stop cycles.


WTF? And now the not very intelligent, artificial intelligence rears its ugly head!

What did we learn? Please, when doing a Google search, ignore the AI Overview and skip to (hopefully) the next round of search results to get the correct answer!
 
I think it is safe to say that this is the most active 'Cherokee' forum on the web and as such, we will always show up at the top of the search results pages. That in itself brings a lot of people here as their first stop for info.

For example. If you do this query on Google: Stop start system not working on my grand cherokee. The very first result on the page is a bunch of links to this forum, not a Grand Cherokee forum.

So I'll cut people some slack here and blame the Google search results as the reason so many Grand owners show up here with their questions.
