Great video❤

[@TheBatteryShop]

We are glad you enjoyed our video!

Thanks for this video, very helpful! I looked at some vids that had you “just pull off the fender”. I tried that and that thing was not going to pop off. My jeep is 3 1/2 years old, and those clips are now very brittle. Did have to buy a rivet tool though. Thanks again!

Hi - You’re welcome and thanks for watching and sharing your experience!

Do the threaded stud posts fit all Aux 14 batteries? The pics on some of the aux 14 batteries don't seem to show that.

That's nise

Hi - Thanks for watching and sharing your opinion!

Interesting they put the aux battery so low in the engine compartment. Kind of makes water fording a bad idea?

[@DanBlackRacing]

Exactly what I was thinking. We are destined for 18" feet of water this year on a off road trip this summer. Now I;m hesitant...

[@sebiues_1614]

Maybe you can just pull the fuse (43 I Believe), then it shouldn't be a problem for the system at least ​@@DanBlackRacing

Will the Stop Start Not Ready Battery Charging sign on Dash automatically turn off once replaced?? (2019 Jeep Wrangler JL Unlimited Sport)

[@TheBatteryShop]

Hi - Thanks for watching! We think so after the battery management system recognizes the proper battery performance. We suggest that you check the vehicle owner’s manual to be sure.

[@ahmedmohammed4291]

Is the large primary battery connected or disconnected when changing the auxiliary battery? If you disconnect it, does it affect the programming?

[@TheBatteryShop]

Hi - Thanks for watching! We left the main battery connected during our auxiliary battery replacement without loss of vehicle computer memories. We suggest that you check the vehicle owner’s manual or a service/repair manual for your particular vehicle about battery registration to be sure.

If you have JL the 2.0L and turbo charger you don’t have an auxiliary battery.
If you get message “Aux switches not available battery charging” you just need to replace your regular battery.

[@TheBatteryShop]

Hi - Thanks for watching and sharing your information.

[@Justinrussophoto]

That's not true. Unless you have the etouque the 2.0l still uses an aux battery .

[@Eric-Franks]

No cam unit required or disconnecting the main battery

[@TheBatteryShop]

Hi - Thanks for watching! We didn't disconnect the main battery so it will keep the memories "alive" during the auxiliary battery replacement.

[@christian1316]

Why would one have to change this battery? If the start stop function comes on the cluster? Or if the car hesitates to start?

[@TheBatteryShop]

Hi - Thanks for watching! You would only have to replace that battery if it fails a test. The auxiliary battery is basically used to keep the vehicle’s system voltage from dropping below a specified level during engine start so thinks like computer, gps, steering angle, radio stations and other systems or user presets don’t reset.

[@andrewhadden9667]

If you're having issues with the ESS (Electronic Start Stop), the aux battery is probably dead. Over time, it will drain your main as well. It's best to replace both batteries.

[@KryptoDemon]

Wait. Are you actually trying to sell this as a better way? Why unscrew a PCM board and flip up the battery when you could easily pull out the transmission , seats and the firewall to get to it....WTF?

[@TheBatteryShop]

Hi - Thanks for watching! Nope, just a different way for folks who are uncomfortable with with removing connections from computers.

[@highrollermob2650]

Bro wtf are you talking about?

[@Silkyjohnson10]

I also pulled my transmission and entire dash to remove this battery. EZ
