first, this is non-gmc, but could be related.
We have a fiber splicing trailer, that we use at work, and it has a ELX-45 converter/charger. It does state that it should "realize full charge" and switch to maintence mode.
this trailer was put together a year ago, and at that time they put a brand new blue top optima battery in it. I am not sure of it's use since then, but I am thinking about zero. Just been sitting.
I pulled it into the shop, and checked voltage on battery and it registered only a couple volts. I then plugged in the converter/charger, and let it sit overnight...
I came in today to a Major boil over on that Optima battery, it was burning hot, hissing loudly out of the vent, and was obviously pressurized bad. after jumping back, and running at first(scared the crap out of me, It looked like it should of blown up right there). I unplugged the power tot he camper, got it pulled outdoors. and let it sit to cool.(it is 20 degrees out)
Now I read on google, that the optima's do not like a quick charge from dead... so that converter was probably pushing lots of amps right out of the gate. and that might be the problem, or the battery was just bad.
anybody run into a similar issue charging optimas from dead?
FYI, battery has cooled, and is being exchanged. but I am not sure I will put it back into this camper, I will probably go with a traditional lead cell 12RV deep cycle battery. Need to figure out a better way to keep the battery and camper ready to go
