Ess battery change

[Joeshek]

Replaced the aux battery and still have the dash saying auto start stop not available.. battery charging.

Brand new aux battery installed and it was fully charged.

I imagine I must have other electrical issues.

Might just be time to sell..

Did you also replace the main? The general rule of thumb is to replace both when one or the other goes bad.

Main is only 14 months old!
This shouldn't be eating up batteries if it is bad again..

Got in vehicle to drive to work this morning
Dash said start stop ready!

Does voltage look OK?
It stated and stopped fine.
Noticed voltage goes to like 12.5 when it's activated

I helped a friend replace the AUX battery who had the same error as you: start/stop not available. The problem was the lithium battery, but the error did not clear when we replaced the battery. He took it to the dealer who cleared the code.

I'm glad mine cleared.
I was going to buy a lithium battery.

 

[Joeshek]

Well that was lived.

Got In the vehicle to drive home and back to the same old message

 

[Joeshek]

Here we go again..
I give up..

Your main battery is probably weak.
Your voltages do NOT look good. Your alternator is charging too high, trying to charge your dead main battery. A fully charged battery should sit at 12.6-12.7 and the alternator will stop charging when it reaches that value.

Hummm..
Earlier today had same voltage and someone said it was fine.... I'm so friggin confused! Lol
My main is only 13 months old..
It shouldn't be going bad already.. or something else is wrong.. this shouldn't be eating batteries like this... do you think?

Replace batteries at the same time.
If you have the time, remove your main battery and charge it, then load test it. Then, unplug the battery current sensor and leave it off for a few minutes, plug it back in, and reinstall your battery.

I'm going to try that I just replaced the aux battery yesterday and I won't be able to take the Main out till the weekend due to the way I work..
Ii shouldn't mess up the new aux battery?

Also have a genius charger and had the Main charger 100% while I was waiting for my new aux battery to come In..

Like I said it worked perfectly this morning when I went to work.. start stop worked like 10 times.
Only thing that was werid was the seats and steering wheel didn't activate when I used the remote start..
That's why I'm wondering if it's more elaborate electrical problems

Seat and steering wheel warmers only kick on when sensed outside temperature is below 40F.

Your main battery, what brand is it?

do you own a voltmeter?
