No Iam definitely weighing my options and I agree, my main could be going bad. This is a 2021 driven mostly in less than 10 mile trips twice a day. I would like to get rid of the auxiliary battery since I don't use ESS. Then I've only got one battery to check and maintain.
When was the last time that you had the batteries on a charger? It wouldn't take long if you tossed on a trickle charger on just the aux early in the evening and when it finishes, toss it on the main. Have the IBS connector pulled at that time. In the morning, reconnect your battery cables. Then plug in the IBS connector.
I've never charged the battery. What is the downside of removing the auxiliary battery in my situation?
The Aux Battery is there to keep the computers from rebooting due to low voltage during ESS restarts. If you always hit the dash button for ESS, it doesn't really affect you. Since they are paralleled together, removing the Aux Battery actually lowers total capacity. It can also cause warranty issues, depending on the dealer.
Just keep in mind that ESS is never disabled. The button on the dash just prevents the engine from turning off when ESS calls for it. The Tazer just reminds the computer what position you want the button in.
Those short trips over that period of time means those batteries were actually never fully charged. That kills batteries.
If it tested even a bit weak on one of those cheapie testers - then it's weak.
This is what I'm wondering about. I hear people just pull the negative and the fuse and leave the aux in there. Doing it your way has everything worked accordingly since? Like does ass still work, any electrical demons popup? I want to go this route but im wondering if it would be best to also get a yellow/red top battery with the biggest capacity that can fit. My main is original and 2021. Ass isnt working atm. Well i should say it works once in a blue moon but i take mostly short trips to work and back but plan on doing road trips in the near future.
ESS works even without the aux battery. If you are doing short drives, you are killing batteries. Use a battery charger/tender. The reason ESS isn't always working for you now is a sign your batteries are LOW. Short drives are battery killers - even the main doesn't like that.
I actually turn ass off by default everytime i get in the jeep but i had noticed before hand it wasnt always working. And i knew enough from reading over time about ass working even without the aux. I dont mind just hitting the button but from what im hearing the aux batteries are just crap in general. My thing is id rather just have one battery to maintain then 2. Which is why i suggested a bigger main.
Yes but this is where a multimeter becomes your friend and necessary to have in the tool box or kept in the truck. Use the tool to do a load test. If your battery is reading 12.4v, charge it up.
I have not had any issues with this setup thus far but I never use start stop and have a tazer that eliminates the need to push the button everytime I get in.
