H8 Group battery install

[BlueHemi1500]

I'm on the H8 AGM bandwagon. I bought mine from SAM's club they even installed it for me, just about 1 year ago. I have the plastic part and the orginal battery blanket in a lip lock bag. I did buy the H8 battery blanket from the dealer's parts shop. I did have a few electrical blips, but those are well documented. The next day, the little blips were all gone. Now, when I was in the research mode, there were a few posts on various forums how there was a potetnial for damage that could be done with the bigger battery. I have not noted any problems in the year I have had the new battery in the truck.
IMHO - I would fully recommend.

Get an H7 anti gravity battery. It has more AMPs than any H8. I have one and it’s amazing. Expensive but really good.

That's expensive, even for a lithium battery. Which also don't work well in the cold.

My understand is that they aren’t the best if you live in a very cold environment and park outside. I live in the Midwest and it gets cold but I always park inside and even if I didn’t it wouldn’t be outside for weeks or anything. I haven’t had any issues yet and it’s amazingly lighter than stock.

I just had to replace my battery. 21 1500 Bighorn etorque. Turned it on after and it threw a check engine, traction control, stop/start, and "temporary 4wd disabled". After letting it warm up (it's very cold here now, as are a lot of places), and then a couple stop/start cycles (waiting some time between each), the check engine light is out but the others warnings remain. Tested 4wd, it works fine, but still says it's disabled on restart. Didn't have time to leave it disconnected, it's actually not at my house. Tried the two fingered salute uconnect reboot with no change in behavior. Hoping it will clear itself over the next couple days but my wife's Grand Cherokee did the same crap and never cleared. It cleared after she got it repaired after hitting a deer though. Maybe that's because the battery was disconnected for an extended period.

I like all of the features on modern vehicles, but what happened to the days where you could simply replace a battery and be on your way? So much these days is just a constant battle.

I'd appreciate hearing if anyone has any ideas on how to clear these codes. Maybe it just needs disconnected for a while?

Thanks!
