Replace main batt disco negative for ess batt

[RenegadeJeeper]

Hi team here's my conundrum I replaced the main battery with an H7 not AGM but H7 battery today
ESS negative cable removed from main battery today
Pulled fuse F42I believe as
Headlights are flickering still after replacing main battery
I disable ESS when I drive now as well too
Battery voltage 14.3 when at a stop light
Should I be worried my lights are flickering no other Bells and whistles are flashing

At stoplight voltage drops to like 13.3 to 12.9 the goes back to 14.2 or 3

For a 2018 Wrangler, you have the wrong cable disconnected. The cable connected to the battery in this picture is the aux battery cable.

Expect an ealry failure of your lead acid (not AGM) battery. The charging system is designed for the higher charging rate of an AGM battery and not the lower charging rate of a lead acid battery.

Well I feel dumb af.
Thank you
That is the only battery I can find unless I wanted to go to auto zone and spend 255.
150 for 3 year warranty over 255 for agm 3 year.
I don't go overlanding and there is always a wally here In Oklahoma.
And covid screws everything still.

You’re just being cheap.

Ask me how that's cheap when no one has one in stock and I have to drive almost 50 miles to the closest store with agm battery?
Oh and I work 11 hour days...
