By chance do you have a link for the charger you bought? I have an older one but when I need a new battery I will upgrade from the OEM to something better and I should probably get a new charger as well. ThanksMy procedure is now refined. I have a big Odyssey battery in my JL and whatever brand aux battery I find cheapest, because I have had 3 different brands and they all look like they came out of the same factory...that includes the OEM. The Odyssey is a pure lead high performance AGM and should last up to 10 years. It is 5 years old now. So when the aux fails, the dash does some wonky things. I just get a new one, set aside about 45 min and dig in there and replace it.
So why not bypass or disable the aux? Because I have the lifetime Mopar warranty. I have to keep it stock, so I deal with it. On the Gladiator, the aux failed at 35k miles, right when I bought the truck. So they covered it under the 3/36 warranty and replaced both, even though the main battery was still good. That is their procedure. So just like the JL, the OEM aux lasted 3 years. That seems to be their lifespan. I´ll put an Odyssey in the Gladiator when the replacement OEM battery gets just past the 3 year mark, which is in November of 2026. I really want to eliminate the aux at that point and not even have the dead weight of it in there.
Btw, if you get a pure lead high performance AGM like an Odyssey or Optima, get an Optima or similar charger for it. LOTS of guys think their Optimas failed when the reality is they were drained down to a level that their standard chargers could not recover them. They actually just needed the proper charger to bring them back.
So if anyone has an Optima in the Central Indiana area that has failed, bring it to me and I will take it off your hands! LOL. Just kidding. You can bring it to me or find someone with an Optima charger or one like it designed for these batteries and we can see if we can recover it. I have the little 400 charger and it is the best battery charger I ever had. Not fast, but it is really good. I´d bet their bigger one is even better. But it ain´t cheap.
