I've been in the high performance and car audio industry for years, and have never seen an Optima do that! Holy crap what a bad deal! I guess anyone can make a bad product once in a while, but what a way to find it!
I deep cycyle those Optima batteries pretty regularly and never had probs with them. the one in my Mustang was about 6 years old and had gone through 9 race cars and 2 competition audio cars before it just quit holding a full charge.
However, I don't run them i my daily drivers for one big fact... They need to be deep cycyled to retain their quality. Meaning, you have to run these things down hard once in a while to keep them good, and you just don't do that with average driving.
