My recent post about my 2 problematic Delco’s I was just thinking C5 my other cars weren’t considered. I have had no problem with them. So we are talking just talking C5’s here???

I have a Optima yellow top in my C5 for 4 plus years now.....zero problems, notta, zilch.
Now the dozen or so red tops are a different story. Never let them discharge because they loose allot. Other than that they are okay. Still, I would definitely recommend a red top over the possible leaky Delco.
